We will probably add optional +commands to allow the client to select whether a hardware token is used +to store the key. Configuration options to 'GPGSM' can be used to +restrict the use of this command. + + GENKEY + + 'GPGSM' checks whether this command is allowed and then does an +INQUIRY to get the key parameters, the client should then send the key +parameters in the native format: + + S: INQUIRE KEY_PARAM native + C: D foo:fgfgfg + C: D bar + C: END + + Please note that the server may send Status info lines while reading +the data lines from the client.

To allow multiple patterns (which are ORed during the +search) quoting is required: Spaces are to be translated into "+" or +into "%20"; in turn this requires that the usual escape quoting rules +are done. + + LISTSECRETKEYS PATTERN + + Lists only the keys where a secret key is available. + + The list commands are affected by the option + + OPTION list-mode=MODE + + where mode may be: +'0' + Use default (which is usually the same as 1). +'1' + List only the internal keys. +'2' + List only the external keys. +'3' + List internal and external keys. + + Note that options are valid for the entire session. + + +File: gnupg.info, Node: GPGSM EXPORT, Next: GPGSM IMPORT, Prev: GPGSM LISTKEYS, Up: GPGSM Protocol + +5.6.7 Export certificates +------------------------- + +To export certificate from the internal key database the command: + + EXPORT [--data [--armor] [--base64]] [--] PATTERN + + is used. To allow multiple patterns (which are ORed) quoting is +required: Spaces are to be translated into "+" or into "%20"; in turn +this requires that the usual escape quoting rules are done. + + If the '--data' option has not been given, the format of the output +depends on what was set with the 'OUTPUT' command. When using PEM +encoding a few informational lines are prepended. + + If the '--data' has been given, a target set via 'OUTPUT' is ignored +and the data is returned inline using standard 'D'-lines. This avoids +the need for an extra file descriptor. In this case the options +'--armor' and '--base64' may be used in the same way as with the +'OUTPUT' command. + + +File: gnupg.info, Node: GPGSM IMPORT, Next: GPGSM DELETE, Prev: GPGSM EXPORT, Up: GPGSM Protocol + +5.6.8 Import certificates +------------------------- + +To import certificates into the internal key database, the command + + IMPORT [--re-import] + + is used. The data is expected on the file descriptor set with the +'INPUT' command. Certain checks are performed on the certificate. Note +that the code will also handle PKCS#12 files and import private keys; a +helper program is used for that. + + With the option '--re-import' the input data is expected to a be a +linefeed separated list of fingerprints. The command will re-import the +corresponding certificates; that is they are made permanent by removing +their ephemeral flag. + + +File: gnupg.info, Node: GPGSM DELETE, Next: GPGSM GETAUDITLOG, Prev: GPGSM IMPORT, Up: GPGSM Protocol + +5.6.9 Delete certificates +------------------------- + +To delete a certificate the command + + DELKEYS PATTERN + + is used.

The + leading two dashes usually used with OPT shall not be given. +'offline' + Return OK if the connection is in offline mode. This may be either + due to a 'OPTION offline=1' or due to 'gpgsm' being started with + option '--disable-dirmngr'. + + +File: gnupg.info, Node: GPGSM OPTION, Prev: GPGSM GETINFO, Up: GPGSM Protocol + +5.6.12 Session options +---------------------- + +The standard Assuan option handler supports these options. + + OPTION NAME[=VALUE] + + These NAMEs are recognized: + +'putenv' + Change the session's environment to be passed via gpg-agent to + Pinentry. VALUE is a string of the form '[=[]]'. If + only '' is given the environment variable '' is removed + from the session environment, if '=' is given that environment + variable is set to the empty string, and if '' is given it + is set to that string. + +'display' + Set the session environment variable 'DISPLAY' is set to VALUE. +'ttyname' + Set the session environment variable 'GPG_TTY' is set to VALUE. +'ttytype' + Set the session environment variable 'TERM' is set to VALUE. +'lc-ctype' + Set the session environment variable 'LC_CTYPE' is set to VALUE. +'lc-messages' + Set the session environment variable 'LC_MESSAGES' is set to VALUE. +'xauthority' + Set the session environment variable 'XAUTHORITY' is set to VALUE. +'pinentry-user-data' + Set the session environment variable 'PINENTRY_USER_DATA' is set to + VALUE. + +'include-certs' + This option overrides the command line option '--include-certs'. A + VALUE of -2 includes all certificates except for the root + certificate, -1 includes all certificates, 0 does not include any + certificates, 1 includes only the signers certificate and all other + positive values include up to VALUE certificates starting with the + signer cert. + +'list-mode' + *Note gpgsm-cmd listkeys::. + +'list-to-output' + If VALUE is true the output of the list commands (*note gpgsm-cmd + listkeys::) is written to the file descriptor set with the last + 'OUTPUT' command. If VALUE is false the output is written via data + lines; this is the default. + +'with-validation' + If VALUE is true for each listed certificate the validation status + is printed. This may result in the download of a CRL or the user + being asked about the trustworthiness of a root certificate. The + default is given by a command line option (*note gpgsm-option + --with-validation::). + +'with-secret' + If VALUE is true certificates with a corresponding private key are + marked by the list commands. + +'validation-model' + This option overrides the command line option 'validation-model' + for the session. (*Note gpgsm-option --validation-model::.) + +'with-key-data' + This option globally enables the command line option + '--with-key-data'. (*Note gpgsm-option --with-key-data::.) + +'enable-audit-log' + If VALUE is true data to write an audit log is gathered. (*Note + gpgsm-cmd getauditlog::.) + +'allow-pinentry-notify' + If this option is used notifications about the launch of a Pinentry + are passed back to the client. + +'with-ephemeral-keys' + If VALUE is true ephemeral certificates are included in the output + of the list commands. + +'no-encrypt-to' + If this option is used all keys set by the command line option + '--encrypt-to' are ignored. + +'offline' + If VALUE is true or VALUE is not given all network access is + disabled for this session.

Note that you cannot abbreviate this command. + +'--dump-options' + Print a list of all available options and commands. Note that you + cannot abbreviate this command. + +'--server' + Run in server mode and wait for commands on the 'stdin'. The + default mode is to create a socket and listen for commands there. + +'--multi-server' + Run in server mode and wait for commands on the 'stdin' as well as + on an additional Unix Domain socket. The server command 'GETINFO' + may be used to get the name of that extra socket. + +'--daemon' + Run the program in the background. This option is required to + prevent it from being accidentally running in the background. + + +File: gnupg.info, Node: Scdaemon Options, Next: Card applications, Prev: Scdaemon Commands, Up: Invoking SCDAEMON + +6.2 Option Summary +================== + +'--options FILE' + Reads configuration from FILE instead of from the default per-user + configuration file. The default configuration file is named + 'scdaemon.conf' and expected in the '.gnupg' directory directly + below the home directory of the user. + +'--homedir DIR' + Set the name of the home directory to DIR. If this option is not + used, the home directory defaults to '~/.gnupg'. It is only + recognized when given on the command line. It also overrides any + home directory stated through the environment variable 'GNUPGHOME' + or (on Windows systems) by means of the Registry entry + HKCU\SOFTWARE\GNU\GNUPG:HOMEDIR. + + On Windows systems it is possible to install GnuPG as a portable + application. In this case only this command line option is + considered, all other ways to set a home directory are ignored. + + To install GnuPG as a portable application under Windows, create an + empty file named 'gpgconf.ctl' in the same directory as the tool + 'gpgconf.exe'. The root of the installation is then that + directory; or, if 'gpgconf.exe' has been installed directly below a + directory named 'bin', its parent directory. You also need to make + sure that the following directories exist and are writable: + 'ROOT/home' for the GnuPG home and 'ROOT/usr/local/var/cache/gnupg' + for internal cache files. + +'-v' +'--verbose' + Outputs additional information while running. You can increase the + verbosity by giving several verbose commands to 'gpgsm', such as + '-vv'. + +'--debug-level LEVEL' + Select the debug level for investigating problems. LEVEL may be a + numeric value or a keyword: + + 'none' + No debugging at all. A value of less than 1 may be used + instead of the keyword. + 'basic' + Some basic debug messages. A value between 1 and 2 may be + used instead of the keyword. + 'advanced' + More verbose debug messages. A value between 3 and 5 may be + used instead of the keyword. + 'expert' + Even more detailed messages. A value between 6 and 8 may be + used instead of the keyword. + 'guru' + All of the debug messages you can get. A value greater than 8 + may be used instead of the keyword. The creation of hash + tracing files is only enabled if the keyword is used. + + How these messages are mapped to the actual debugging flags is not + specified and may change with newer releases of this program. They + are however carefully selected to best aid in debugging. + + Note: All debugging options are subject to change and thus + should not be used by any application program. As the name + says, they are only used as helpers to debug problems. + +'--debug FLAGS' + This option is only useful for debugging and the behavior may + change at any time without notice. FLAGS are bit encoded and may + be given in usual C-Syntax. The currently defined bits are: + + '0 (1)' + command I/O + '1 (2)' + values of big number integers + '2 (4)' + low level crypto operations + '5 (32)' + memory allocation + '6 (64)' + caching + '7 (128)' + show memory statistics + '9 (512)' + write hashed data to files named 'dbgmd-000*' + '10 (1024)' + trace Assuan protocol. See also option + '--debug-assuan-log-cats'. + '11 (2048)' + trace APDU I/O to the card. This may reveal sensitive data. + '12 (4096)' + trace some card reader related function calls. + +'--debug-all' + Same as '--debug=0xffffffff' + +'--debug-wait N' + When running in server mode, wait N seconds before entering the + actual processing loop and print the pid. This gives time to + attach a debugger. + +'--debug-ccid-driver' + Enable debug output from the included CCID driver for smartcards. + Using this option twice will also enable some tracing of the T=1 + protocol. Note that this option may reveal sensitive data. + +'--debug-disable-ticker' + This option disables all ticker functions like checking for card + insertions. + +'--debug-allow-core-dump' + For security reasons we won't create a core dump when the process + aborts. For debugging purposes it is sometimes better to allow + core dump. This option enables it and also changes the working + directory to '/tmp' when running in '--server' mode. + +'--debug-log-tid' + This option appends a thread ID to the PID in the log output. + +'--debug-assuan-log-cats CATS' + Changes the active Libassuan logging categories to CATS. The value + for CATS is an unsigned integer given in usual C-Syntax. A value + of 0 switches to a default category. If this option is not used + the categories are taken from the environment variable + 'ASSUAN_DEBUG'. Note that this option has only an effect if the + Assuan debug flag has also been with the option '--debug'. For a + list of categories see the Libassuan manual. + +'--no-detach' + Don't detach the process from the console. This is mainly useful + for debugging. + +'--listen-backlog N' + Set the size of the queue for pending connections. The default is + 64. This option has an effect only if '--multi-server' is also + used. + +'--log-file FILE' + Append all logging output to FILE. This is very helpful in seeing + what the agent actually does. Use 'socket://' to log to socket. + +'--pcsc-driver LIBRARY' + Use LIBRARY to access the smartcard reader. The current default is + 'libpcsclite.so'. Instead of using this option you might also want + to install a symbolic link to the default file name (e.g. from + 'libpcsclite.so.1'). + +'--ctapi-driver LIBRARY' + Use LIBRARY to access the smartcard reader. The current default is + 'libtowitoko.so'. Note that the use of this interface is + deprecated; it may be removed in future releases. + +'--disable-ccid' + Disable the integrated support for CCID compliant readers. This + allows falling back to one of the other drivers even if the + internal CCID driver can handle the reader. Note, that CCID + support is only available if libusb was available at build time. + +'--reader-port NUMBER_OR_STRING' + This option may be used to specify the port of the card terminal. + A value of 0 refers to the first serial device; add 32768 to access + USB devices. The default is 32768 (first USB device). PC/SC or + CCID readers might need a string here; run the program in verbose + mode to get a list of available readers. The default is then the + first reader found. + + To get a list of available CCID readers you may use this command: + echo scd getinfo reader_list \ + | gpg-connect-agent --decode | awk '/^D/ {print $2}' + +'--card-timeout N' + If N is not 0 and no client is actively using the card, the card + will be powered down after N seconds. Powering down the card + avoids a potential risk of damaging a card when used with certain + cheap readers. This also allows applications that are not aware of + Scdaemon to access the card. The disadvantage of using a card + timeout is that accessing the card takes longer and that the user + needs to enter the PIN again after the next power up. + + Note that with the current version of Scdaemon the card is powered + down immediately at the next timer tick for any value of N other + than 0. + +'--enable-pinpad-varlen' + Please specify this option when the card reader supports variable + length input for pinpad (default is no). For known readers (listed + in ccid-driver.c and apdu.c), this option is not needed. Note that + if your card reader doesn't supports variable length input but you + want to use it, you need to specify your pinpad request on your + card. + +'--disable-pinpad' + Even if a card reader features a pinpad, do not try to use it. + +'--deny-admin' + This option disables the use of admin class commands for card + applications where this is supported. Currently we support it for + the OpenPGP card. This option is useful to inhibit accidental + access to admin class command which could ultimately lock the card + through wrong PIN numbers. Note that GnuPG versions older than + 2.0.11 featured an '--allow-admin' option which was required to use + such admin commands. This option has no more effect today because + the default is now to allow admin commands. + +'--disable-application NAME' + This option disables the use of the card application named NAME. + This is mainly useful for debugging or if a application with lower + priority should be used by default. + + All the long options may also be given in the configuration file +after stripping off the two leading dashes. + + +File: gnupg.info, Node: Card applications, Next: Scdaemon Configuration, Prev: Scdaemon Options, Up: Invoking SCDAEMON + +6.3 Description of card applications +==================================== + +'scdaemon' supports the card applications as described below. + +* Menu: + +* OpenPGP Card:: The OpenPGP card application +* NKS Card:: The Telesec NetKey card application +* DINSIG Card:: The DINSIG card application +* PKCS#15 Card:: The PKCS#15 card application +* Geldkarte Card:: The Geldkarte application +* SmartCard-HSM:: The SmartCard-HSM application +* Undefined Card:: The Undefined stub application + + +File: gnupg.info, Node: OpenPGP Card, Next: NKS Card, Up: Card applications + +6.3.1 The OpenPGP card application "openpgp" +-------------------------------------------- + +This application is currently only used by 'gpg' but may in future also +be useful with 'gpgsm'.

'watchgnupg' is a simple listener +for such a socket. It ameliorates the output with a time stamp and +makes sure that long lines are not interspersed with log output from +other utilities. This tool is not available for Windows. + +'watchgnupg' is commonly invoked as + + watchgnupg --force $(gpgconf --list-dirs socketdir)/S.log + +This starts it on the current terminal for listening on the standard +logging socket (which is either '~/.gnupg/S.log' or +'/var/run/user/UID/gnupg/S.log'). + +'watchgnupg' understands these options: + +'--force' + Delete an already existing socket file. + +'--tcp N' + Instead of reading from a local socket, listen for connects on TCP + port N. + +'--time-only' + Do not print the date part of the timestamp. + +'--verbose' + Enable extra informational output. + +'--version' + Print version of the program and exit. + +'--help' + Display a brief help page and exit. + + +Examples +******** + + $ watchgnupg --force --time-only $(gpgconf --list-dirs socketdir)/S.log + + This waits for connections on the local socket (e.g. +'/home/foo/.gnupg/S.log') and shows all log entries. To make this work +the option 'log-file' needs to be used with all modules which logs are +to be shown. The suggested entry for the configuration files is: + + log-file socket:// + + If the default socket as given above and returned by "echo $(gpgconf +-list-dirs socketdir)/S.log" is not desired an arbitrary socket name can +be specified, for example 'socket:///home/foo/bar/mysocket'. For +debugging purposes it is also possible to do remote logging. Take care +if you use this feature because the information is send in the clear +over the network. Use this syntax in the conf files: + + log-file tcp://192.168.1.1:4711 + + You may use any port and not just 4711 as shown above; only IP +addresses are supported (v4 and v6) and no host names. You need to +start 'watchgnupg' with the 'tcp' option. Note that under Windows the +registry entry HKCU\SOFTWARE\GNU\GNUPG:DEFAULTLOGFILE can be used to +change the default log output from 'stderr' to whatever is given by that +entry. However the only useful entry is a TCP name for remote +debugging. + + +File: gnupg.info, Node: gpgv, Next: addgnupghome, Prev: watchgnupg, Up: Helper Tools + +9.2 Verify OpenPGP signatures +============================= + +'gpgv' is an OpenPGP signature verification tool. + + This program is actually a stripped-down version of 'gpg' which is +only able to check signatures. It is somewhat smaller than the +fully-blown 'gpg' and uses a different (and simpler) way to check that +the public keys used to make the signature are valid. There are no +configuration files and only a few options are implemented. + + 'gpgv' assumes that all keys in the keyring are trustworthy. That +does also mean that it does not check for expired or revoked keys. + + If no '--keyring' option is given, 'gpgv' looks for a "default" +keyring named 'trustedkeys.kbx' (preferred) or 'trustedkeys.gpg' in the +home directory of GnuPG, either the default home directory or the one +set by the '--homedir' option or the 'GNUPGHOME' environment variable. +If any '--keyring' option is used, 'gpgv' will not look for the default +keyring. The '--keyring' option may be used multiple times and all +specified keyrings will be used together. + + + 'gpgv' recognizes these options: + +'--verbose' +'-v' + Gives more information during processing. If used twice, the input + data is listed in detail. + +'--quiet' +'-q' + Try to be as quiet as possible. + +'--keyring FILE' + Add FILE to the list of keyrings. If FILE begins with a tilde and + a slash, these are replaced by the HOME directory. If the filename + does not contain a slash, it is assumed to be in the home-directory + ("~/.gnupg" if -homedir is not used). + +'--output FILE' +'-o FILE' + Write output to FILE; to write to stdout use '-'. This option can + be used to get the signed text from a cleartext or binary + signature; it also works for detached signatures, but in that case + this option is in general not useful. Note that an existing file + will be overwritten. + +'--status-fd N' + Write special status strings to the file descriptor N. See the + file DETAILS in the documentation for a listing of them. + +'--logger-fd n' + Write log output to file descriptor 'n' and not to stderr. + +'--log-file file' + Same as '--logger-fd', except the logger data is written to file + 'file'. Use 'socket://' to log to socket. + +'--ignore-time-conflict' + GnuPG normally checks that the timestamps associated with keys and + signatures have plausible values. However, sometimes a signature + seems to be older than the key due to clock problems. This option + turns these checks into warnings. + +'--homedir DIR' + Set the name of the home directory to DIR. If this option is not + used, the home directory defaults to '~/.gnupg'. It is only + recognized when given on the command line. It also overrides any + home directory stated through the environment variable 'GNUPGHOME' + or (on Windows systems) by means of the Registry entry + HKCU\SOFTWARE\GNU\GNUPG:HOMEDIR. + + On Windows systems it is possible to install GnuPG as a portable + application. In this case only this command line option is + considered, all other ways to set a home directory are ignored. + + To install GnuPG as a portable application under Windows, create an + empty file named 'gpgconf.ctl' in the same directory as the tool + 'gpgconf.exe'. The root of the installation is then that + directory; or, if 'gpgconf.exe' has been installed directly below a + directory named 'bin', its parent directory. You also need to make + sure that the following directories exist and are writable: + 'ROOT/home' for the GnuPG home and 'ROOT/usr/local/var/cache/gnupg' + for internal cache files. + +'--weak-digest name' + Treat the specified digest algorithm as weak. Signatures made over + weak digests algorithms are normally rejected. This option can be + supplied multiple times if multiple algorithms should be considered + weak. MD5 is always considered weak, and does not need to be + listed explicitly. + +'--enable-special-filenames' + This option enables a mode in which filenames of the form '-&n', + where n is a non-negative decimal number, refer to the file + descriptor n and not to a file with that name. + + The program returns 0 if everything is fine, 1 if at least one +signature was bad, and other error codes for fatal errors. + +9.2.1 Examples +-------------- + +gpgv 'pgpfile' +gpgv 'sigfile' ['datafile'] + Verify the signature of the file. The second form is used for + detached signatures, where 'sigfile' is the detached signature + (either ASCII-armored or binary) and 'datafile' contains the signed + data; if 'datafile' is "-" the signed data is expected on 'stdin'; + if 'datafile' is not given the name of the file holding the signed + data is constructed by cutting off the extension (".asc", ".sig" or + ".sign") from 'sigfile'. + +9.2.2 Environment +----------------- + +HOME + Used to locate the default home directory. + +GNUPGHOME + If set directory used instead of "~/.gnupg". + +9.2.3 FILES +----------- + +~/.gnupg/trustedkeys.gpg + The default keyring with the allowed keys. + + 'gpg'(1) + + +File: gnupg.info, Node: addgnupghome, Next: gpgconf, Prev: gpgv, Up: Helper Tools + +9.3 Create .gnupg home directories +================================== + +If GnuPG is installed on a system with existing user accounts, it is +sometimes required to populate the GnuPG home directory with existing +files.

It is +designed not to be invoked manually by the user, but automatically by +graphical user interfaces (GUI).(1) + + 'gpgconf' provides access to the configuration of one or more +components of the GnuPG system. These components correspond more or +less to the programs that exist in the GnuPG framework, like GPG, GPGSM, +DirMngr, etc. But this is not a strict one-to-one relationship. Not +all configuration options are available through 'gpgconf'. 'gpgconf' +provides a generic and abstract method to access the most important +configuration options that can feasibly be controlled via such a +mechanism. + + 'gpgconf' can be used to gather and change the options available in +each component, and can also provide their default values. 'gpgconf' +will give detailed type information that can be used to restrict the +user's input without making an attempt to commit the changes. + + 'gpgconf' provides the backend of a configuration editor. The +configuration editor would usually be a graphical user interface program +that displays the current options, their default values, and allows the +user to make changes to the options. These changes can then be made +active with 'gpgconf' again. Such a program that uses 'gpgconf' in this +way will be called GUI throughout this section. + +* Menu: + +* Invoking gpgconf:: List of all commands and options. +* Format conventions:: Formatting conventions relevant for all commands. +* Listing components:: List all gpgconf components. +* Checking programs:: Check all programs known to gpgconf. +* Listing options:: List all options of a component. +* Changing options:: Changing options of a component. +* Listing global options:: List all global options. +* Querying versions:: Get and compare software versions. +* Files used by gpgconf:: What files are used by gpgconf. + + ---------- Footnotes ---------- + + (1) Please note that currently no locking is done, so concurrent +access should be avoided.

A profile is divided into sections using the + bracketed component name. Each section then lists the option which + shall go into the respective configuration file. + +'--apply-defaults' + Update all configuration files with values taken from the global + configuration file (usually '/etc/gnupg/gpgconf.conf'). + +'--list-dirs [NAMES]' + Lists the directories used by 'gpgconf'. One directory is listed + per line, and each line consists of a colon-separated list where + the first field names the directory type (for example 'sysconfdir') + and the second field contains the percent-escaped directory. + Although they are not directories, the socket file names used by + 'gpg-agent' and 'dirmngr' are printed as well. Note that the + socket file names and the 'homedir' lines are the default names and + they may be overridden by command line switches. If NAMES are + given only the directories or file names specified by the list + names are printed without any escaping. + +'--list-config [FILENAME]' + List the global configuration file in a colon separated format. If + FILENAME is given, check that file instead. + +'--check-config [FILENAME]' + Run a syntax check on the global configuration file. If FILENAME + is given, check that file instead. + +'--query-swdb PACKAGE_NAME [VERSION_STRING]' + Returns the current version for PACKAGE_NAME and if VERSION_STRING + is given also an indicator on whether an update is available. The + actual file with the software version is automatically downloaded + and checked by 'dirmngr'. 'dirmngr' uses a thresholds to avoid + download the file too often and it does this by default only if it + can be done via Tor. To force an update of that file this command + can be used: + + gpg-connect-agent --dirmngr 'loadswdb --force' /bye + +'--reload [COMPONENT]' + Reload all or the given component. This is basically the same as + sending a SIGHUP to the component. Components which don't support + reloading are ignored. Without COMPONENT or by using "all" for + COMPONENT all components which are daemons are reloaded. + +'--launch [COMPONENT]' + If the COMPONENT is not already running, start it. 'component' + must be a daemon. This is in general not required because the + system starts these daemons as needed. However, external software + making direct use of 'gpg-agent' or 'dirmngr' may use this command + to ensure that they are started. Using "all" for COMPONENT + launches all components which are daemons. + +'--kill [COMPONENT]' + Kill the given component that runs as a daemon, including + 'gpg-agent', 'dirmngr', and 'scdaemon'. A 'component' which does + not run as a daemon will be ignored. Using "all" for COMPONENT + kills all components running as daemons. Note that as of now + reload and kill have the same effect for 'scdaemon'. + +'--create-socketdir' + Create a directory for sockets below /run/user or /var/run/user. + This is command is only required if a non default home directory is + used and the /run based sockets shall be used.

The following conventions apply: + + * The GUI program is required to strip off trailing newline and/or + carriage return characters from the output. + + * 'gpgconf' will never leave out fields. If a certain version + provides a certain field, this field will always be present in all + 'gpgconf' versions from that time on. + + * Future versions of 'gpgconf' might append fields to the list. New + fields will always be separated from the previously last field by a + colon separator. The GUI should be prepared to parse the last + field it knows about up until a colon or end of line. + + * Not all fields are defined under all conditions. You are required + to ignore the content of undefined fields. + + There are several standard types for the content of a field: + +verbatim + Some fields contain strings that are not escaped in any way. Such + fields are described to be used _verbatim_. These fields will + never contain a colon character (for obvious reasons). No + de-escaping or other formatting is required to use the field + content. This is for easy parsing of the output, when it is known + that the content can never contain any special characters. + +percent-escaped + Some fields contain strings that are described to be + _percent-escaped_. Such strings need to be de-escaped before their + content can be presented to the user. A percent-escaped string is + de-escaped by replacing all occurrences of '%XY' by the byte that + has the hexadecimal value 'XY'. 'X' and 'Y' are from the set + '0-9a-f'. + +localized + Some fields contain strings that are described to be _localized_. + Such strings are translated to the active language and formatted in + the active character set. + +unsigned number + Some fields contain an _unsigned number_. This number will always + fit into a 32-bit unsigned integer variable. The number may be + followed by a space, followed by a human readable description of + that value (if the verbose option is used). You should ignore + everything in the field that follows the number. + +signed number + Some fields contain a _signed number_. This number will always fit + into a 32-bit signed integer variable. The number may be followed + by a space, followed by a human readable description of that value + (if the verbose option is used). You should ignore everything in + the field that follows the number. + +boolean value + Some fields contain a _boolean value_. This is a number with + either the value 0 or 1. The number may be followed by a space, + followed by a human readable description of that value (if the + verbose option is used). You should ignore everything in the field + that follows the number; checking just the first character is + sufficient in this case. + +option + Some fields contain an _option_ argument. The format of an option + argument depends on the type of the option and on some flags: + + no argument + The simplest case is that the option does not take an argument + at all (TYPE '0'). Then the option argument is an unsigned + number that specifies how often the option occurs. If the + 'list' flag is not set, then the only valid number is '1'. + Options that do not take an argument never have the 'default' + or 'optional arg' flag set. + + number + If the option takes a number argument (ALT-TYPE is '2' or + '3'), and it can only occur once ('list' flag is not set), + then the option argument is either empty (only allowed if the + argument is optional), or it is a number. A number is a + string that begins with an optional minus character, followed + by one or more digits. The number must fit into an integer + variable (unsigned or signed, depending on ALT-TYPE). + + number list + If the option takes a number argument and it can occur more + than once, then the option argument is either empty, or it is + a comma-separated list of numbers as described above. + + string + If the option takes a string argument (ALT-TYPE is 1), and it + can only occur once ('list' flag is not set) then the option + argument is either empty (only allowed if the argument is + optional), or it starts with a double quote character ('"') + followed by a percent-escaped string that is the argument + value. Note that there is only a leading double quote + character, no trailing one. The double quote character is + only needed to be able to differentiate between no value and + the empty string as value. + + string list + If the option takes a string argument and it can occur more + than once, then the option argument is either empty, or it is + a comma-separated list of string arguments as described above. + + The active language and character set are currently determined from +the locale environment of the 'gpgconf' program. + + +File: gnupg.info, Node: Listing components, Next: Checking programs, Prev: Format conventions, Up: gpgconf + +9.4.3 Listing components +------------------------ + +The command '--list-components' will list all components that can be +configured with 'gpgconf'. Usually, one component will correspond to +one GnuPG-related program and contain the options of that program's +configuration file that can be modified using 'gpgconf'. However, this +is not necessarily the case. A component might also be a group of +selected options from several programs, or contain entirely virtual +options that have a special effect rather than changing exactly one +option in one configuration file. + + A component is a set of configuration options that semantically +belong together. Furthermore, several changes to a component can be +made in an atomic way with a single operation. The GUI could for +example provide a menu with one entry for each component, or a window +with one tabulator sheet per component. + + The command '--list-components' lists all available components, one +per line. The format of each line is: + + 'NAME:DESCRIPTION:PGMNAME:' + +NAME + This field contains a name tag of the component. The name tag is + used to specify the component in all communication with 'gpgconf'. + The name tag is to be used _verbatim_. It is thus not in any + escaped format. + +DESCRIPTION + The _string_ in this field contains a human-readable description of + the component.

It runs each program +to test whether it is installed and runnable. This also includes a +syntax check of all config file options of the program. + + The command '--check-programs' lists all available programs, one per +line. The format of each line is: + + 'NAME:DESCRIPTION:PGMNAME:AVAIL:OKAY:CFGFILE:LINE:ERROR:' + +NAME + This field contains a name tag of the program which is identical to + the name of the component. The name tag is to be used _verbatim_. + It is thus not in any escaped format. This field may be empty to + indicate a continuation of error descriptions for the last name. + The description and pgmname fields are then also empty. + +DESCRIPTION + The _string_ in this field contains a human-readable description of + the component.

Options may be gathered +into option groups to allow the GUI to give visual hints to the user +about which options are related. + + The command '--list-options COMPONENT' lists all options (and the +groups they belong to) in the component COMPONENT, one per line. +COMPONENT must be the string in the field NAME in the output of the +'--list-components' command. + + There is one line for each option and each group. First come all +options that are not in any group. Then comes a line describing a +group. Then come all options that belong into each group. Then comes +the next group and so on. There does not need to be any group (and in +this case the output will stop after the last non-grouped option). + + The format of each line is: + + 'NAME:FLAGS:LEVEL:DESCRIPTION:TYPE:ALT-TYPE:ARGNAME:DEFAULT:ARGDEF:VALUE' + +NAME + This field contains a name tag for the group or option. The name + tag is used to specify the group or option in all communication + with 'gpgconf'. The name tag is to be used _verbatim_. It is thus + not in any escaped format. + +FLAGS + The flags field contains an _unsigned number_. Its value is the + OR-wise combination of the following flag values: + + 'group (1)' + If this flag is set, this is a line describing a group and not + an option. + + The following flag values are only defined for options (that is, if + the 'group' flag is not used). + + 'optional arg (2)' + If this flag is set, the argument is optional. This is never + set for TYPE '0' (none) options. + + 'list (4)' + If this flag is set, the option can be given multiple times. + + 'runtime (8)' + If this flag is set, the option can be changed at runtime. + + 'default (16)' + If this flag is set, a default value is available. + + 'default desc (32)' + If this flag is set, a (runtime) default is available. This + and the 'default' flag are mutually exclusive. + + 'no arg desc (64)' + If this flag is set, and the 'optional arg' flag is set, then + the option has a special meaning if no argument is given. + + 'no change (128)' + If this flag is set, 'gpgconf' ignores requests to change the + value. GUI frontends should grey out this option. Note, that + manual changes of the configuration files are still possible. + +LEVEL + This field is defined for options and for groups. It contains an + _unsigned number_ that specifies the expert level under which this + group or option should be displayed. The following expert levels + are defined for options (they have analogous meaning for groups): + + 'basic (0)' + This option should always be offered to the user. + + 'advanced (1)' + This option may be offered to advanced users. + + 'expert (2)' + This option should only be offered to expert users. + + 'invisible (3)' + This option should normally never be displayed, not even to + expert users. + + 'internal (4)' + This option is for internal use only.

It is _percent-escaped_ and _localized_. + +TYPE + This field is only defined for options. It contains an _unsigned + number_ that specifies the type of the option's argument, if any. + The following types are defined: + + Basic types: + + 'none (0)' + No argument allowed. + + 'string (1)' + An _unformatted string_. + + 'int32 (2)' + A _signed number_. + + 'uint32 (3)' + An _unsigned number_. + + Complex types: + + 'pathname (32)' + A _string_ that describes the pathname of a file. The file + does not necessarily need to exist. + + 'ldap server (33)' + A _string_ that describes an LDAP server in the format: + + 'HOSTNAME:PORT:USERNAME:PASSWORD:BASE_DN' + + 'key fingerprint (34)' + A _string_ with a 40 digit fingerprint specifying a + certificate. + + 'pub key (35)' + A _string_ that describes a certificate by user ID, key ID or + fingerprint. + + 'sec key (36)' + A _string_ that describes a certificate with a key by user ID, + key ID or fingerprint. + + 'alias list (37)' + A _string_ that describes an alias list, like the one used + with gpg's group option. The list consists of a key, an equal + sign and space separated values. + + More types will be added in the future. Please see the ALT-TYPE + field for information on how to cope with unknown types. + +ALT-TYPE + This field is identical to TYPE, except that only the types '0' to + '31' are allowed. The GUI is expected to present the user the + option in the format specified by TYPE. But if the argument type + TYPE is not supported by the GUI, it can still display the option + in the more generic basic type ALT-TYPE. The GUI must support all + the defined basic types to be able to display all options. More + basic types may be added in future versions. If the GUI encounters + a basic type it doesn't support, it should report an error and + abort the operation. + +ARGNAME + This field is only defined for options with an argument type TYPE + that is not '0'. In this case it may contain a _percent-escaped_ + and _localized string_ that gives a short name for the argument. + The field may also be empty, though, in which case a short name is + not known. + +DEFAULT + This field is defined only for options for which the 'default' or + 'default desc' flag is set. If the 'default' flag is set, its + format is that of an _option argument_ (*note Format conventions::, + for details). If the default value is empty, then no default is + known. Otherwise, the value specifies the default value for this + option. If the 'default desc' flag is set, the field is either + empty or contains a description of the effect if the option is not + given. + +ARGDEF + This field is defined only for options for which the 'optional arg' + flag is set. If the 'no arg desc' flag is not set, its format is + that of an _option argument_ (*note Format conventions::, for + details). If the default value is empty, then no default is known. + Otherwise, the value specifies the default argument for this + option. If the 'no arg desc' flag is set, the field is either + empty or contains a description of the effect of this option if no + argument is given. + +VALUE + This field is defined only for options. Its format is that of an + _option argument_. If it is empty, then the option is not + explicitly set in the current configuration, and the default + applies (if any). Otherwise, it contains the current value of the + option.

COMPONENT +must be the string in the field NAME in the output of the +'--list-components' command. You have to provide the options that shall +be changed in the following format on standard input: + + 'NAME:FLAGS:NEW-VALUE' + +NAME + This is the name of the option to change. NAME must be the string + in the field NAME in the output of the '--list-options' command. + +FLAGS + The flags field contains an _unsigned number_. Its value is the + OR-wise combination of the following flag values: + + 'default (16)' + If this flag is set, the option is deleted and the default + value is used instead (if applicable). + +NEW-VALUE + The new value for the option. This field is only defined if the + 'default' flag is not set. The format is that of an _option + argument_. If it is empty (or the field is omitted), the default + argument is used (only allowed if the argument is optional for this + option). Otherwise, the option will be set to the specified value. + +The output of the command is the same as that of '--check-options' for +the modified configuration file. + + Examples: + + To set the force option, which is of basic type 'none (0)': + + $ echo 'force:0:1' | gpgconf --change-options dirmngr + + To delete the force option: + + $ echo 'force:16:' | gpgconf --change-options dirmngr + + The '--runtime' option can influence when the changes take effect. + + +File: gnupg.info, Node: Listing global options, Next: Querying versions, Prev: Changing options, Up: gpgconf + +9.4.7 Listing global options +---------------------------- + +Sometimes it is useful for applications to look at the global options +file 'gpgconf.conf'.

'gpgconf' can be used to access this +online database. To allow for offline operations, this feature works by +having 'dirmngr' download a file from 'https://versions.gnupg.org', +checking the signature of that file and storing the file in the GnuPG +home directory. If 'gpgconf' is used and 'dirmngr' is running, it may +ask 'dirmngr' to refresh that file before itself uses the file. + + The command '--query-swdb' returns information for the given package +in a colon delimited format: + +NAME + This is the name of the package as requested. Note that "gnupg" is + a special name which is replaced by the actual package implementing + this version of GnuPG. For this name it is also not required to + specify a version because 'gpgconf' takes its own version in this + case. + +IVERSION + The currently installed version or an empty string. The value is + taken from the command line argument but may be provided by gpg if + not given. + +STATUS + The status of the software package according to this table: + '-' + No information available. This is either because no current + version has been specified or due to an error. + '?' + The given name is not known in the online database. + 'u' + An update of the software is available. + 'c' + The installed version of the software is current. + 'n' + The installed version is already newer than the released + version. + +URGENCY + If the value (the empty string should be considered as zero) is + greater than zero an important update is available. + +ERROR + This returns an 'gpg-error' error code to distinguish between + various failure modes. + +FILEDATE + This gives the date of the file with the version numbers in + standard ISO format ('yyyymmddThhmmss'). The date has been + extracted by 'dirmngr' from the signature of the file. + +VERIFIED + This gives the date in ISO format the file was downloaded. This + value can be used to evaluate the freshness of the information. + +VERSION + This returns the version string for the requested software from the + file. + +RELDATE + This returns the release date in ISO format. + +SIZE + This returns the size of the package as decimal number of bytes. + +HASH + This returns a hexified SHA-2 hash of the package. + +More fields may be added in future to the output. + + +File: gnupg.info, Node: Files used by gpgconf, Prev: Querying versions, Up: gpgconf + +9.4.9 Files used by gpgconf +--------------------------- + +'/etc/gnupg/gpgconf.conf' + If this file exists, it is processed as a global configuration + file.

If this option is not + used, the home directory defaults to '~/.gnupg'. It is only + recognized when given on the command line. It also overrides any + home directory stated through the environment variable 'GNUPGHOME' + or (on Windows systems) by means of the Registry entry + HKCU\SOFTWARE\GNU\GNUPG:HOMEDIR. + + On Windows systems it is possible to install GnuPG as a portable + application. In this case only this command line option is + considered, all other ways to set a home directory are ignored. + + To install GnuPG as a portable application under Windows, create an + empty file named 'gpgconf.ctl' in the same directory as the tool + 'gpgconf.exe'. The root of the installation is then that + directory; or, if 'gpgconf.exe' has been installed directly below a + directory named 'bin', its parent directory. You also need to make + sure that the following directories exist and are writable: + 'ROOT/home' for the GnuPG home and 'ROOT/usr/local/var/cache/gnupg' + for internal cache files. + +'--agent-program FILE' + Specify the agent program to be started if none is running. The + default value is determined by running 'gpgconf' with the option + '--list-dirs'. Note that the pipe symbol ('|') is used for a + regression test suite hack and may thus not be used in the file + name. + +'--dirmngr-program FILE' + Specify the directory manager (keyserver client) program to be + started if none is running. This has only an effect if used + together with the option '--dirmngr'. + +'--dirmngr' + Connect to a running directory manager (keyserver client) instead + of to the gpg-agent.

It has +actually been done this way to get a certificate from CAcert to be used +on a real server. It has only been tested with this CA, but there +shouldn't be any problem to run this against any other CA. + + We start by generating an X.509 certificate signing request. As +there is no need for a configuration file, you may simply enter: + + $ gpgsm --generate-key >example.com.cert-req.pem + Please select what kind of key you want: + (1) RSA + (2) Existing key + (3) Existing key from card + Your selection? 1 + + I opted for creating a new RSA key. The other option is to use an +already existing key, by selecting '2' and entering the so-called +keygrip. Running the command 'gpgsm --dump-secret-key USERID' shows you +this keygrip. Using '3' offers another menu to create a certificate +directly from a smart card based key. + + Let's continue: + + What keysize do you want? (3072) + Requested keysize is 3072 bits + + Hitting enter chooses the default RSA key size of 3072 bits. Keys +smaller than 2048 bits are too weak on the modern Internet. If you +choose a larger (stronger) key, your server will need to do more work. + + Possible actions for a RSA key: + (1) sign, encrypt + (2) sign + (3) encrypt + Your selection? 1 + + Selecting "sign" enables use of the key for Diffie-Hellman key +exchange mechanisms (DHE and ECDHE) in TLS, which are preferred because +they offer forward secrecy. Selecting "encrypt" enables RSA key +exchange mechanisms, which are still common in some places. Selecting +both enables both key exchange mechanisms. + + Now for some real data: + + Enter the X.509 subject name: CN=example.com + + This is the most important value for a server certificate. Enter +here the canonical name of your server machine. You may add other +virtual server names later. + + E-Mail addresses (end with an empty line): + > + + We don't need email addresses in a TLS server certificate and CAcert +would anyway ignore such a request. Thus just hit enter. + + If you want to create a client certificate for email encryption, this +would be the place to enter your mail address (e.g. ). +You may enter as many addresses as you like, however the CA may not +accept them all or reject the entire request. + + Enter DNS names (optional; end with an empty line): + > example.com + > www.example.com + > + + Here I entered the names of the services which the machine actually +provides. You almost always want to include the canonical name here +too. The browser will accept a certificate for any of these names. As +usual the CA must approve all of these names. + + URIs (optional; end with an empty line): + > + + It is possible to insert arbitrary URIs into a certificate; for a +server certificate this does not make sense. + + Create self-signed certificate? (y/N) + + Since we are creating a certificate signing request, and not a full +certificate, we answer no here, or just hit enter for the default. + + We have now entered all required information and 'gpgsm' will display +what it has gathered and ask whether to create the certificate request: + + These parameters are used: + Key-Type: RSA + Key-Length: 3072 + Key-Usage: sign, encrypt + Name-DN: CN=example.com + Name-DNS: example.com + Name-DNS: www.example.com + + Proceed with creation? (y/N) y + + 'gpgsm' will now start working on creating the request. As this +includes the creation of an RSA key it may take a while. During this +time you will be asked 3 times for a passphrase to protect the created +private key on your system. A pop up window will appear to ask for it. +The first two prompts are for the new passphrase and for re-entering it; +the third one is required to actually create the certificate signing +request. + + When it is ready, you should see the final notice: + + Ready.

The commonly used one is the file +'pubring.kbx' in the '.gnupg' directory. It contains all X.509 +certificates as well as OpenPGP keys. + +When called the standard way, e.g.: + + 'kbxutil ~/.gnupg/pubring.kbx' + +it lists all records (called blobs) with there meta-information in a +human readable format. + +To see statistics on the keybox in question, run it using + + 'kbxutil --stats ~/.gnupg/pubring.kbx' + +and you get an output like: + + Total number of blobs: 99 + header: 1 + empty: 0 + openpgp: 0 + x509: 98 + non flagged: 81 + secret flagged: 0 + ephemeral flagged: 17 + + In this example you see that the keybox does not have any OpenPGP +keys but contains 98 X.509 certificates and a total of 17 keys or +certificates are flagged as ephemeral, meaning that they are only +temporary stored (cached) in the keybox and won't get listed using the +usual commands provided by 'gpgsm' or 'gpg'. 81 certificates are stored +in a standard way and directly available from 'gpgsm'. + +To find duplicated certificates and keyblocks in a keybox file (this +should not occur but sometimes things go wrong), run it using + + 'kbxutil --find-dups ~/.gnupg/pubring.kbx' + + +File: gnupg.info, Node: Debugging Hints, Next: Common Problems, Prev: Debugging Tools, Up: Debugging + +13.2 Various hints on debugging +=============================== + + * How to find the IP address of a keyserver + + If a round robin URL of is used for a keyserver (e.g. + subkeys.gnupg.org); it is not easy to see what server is actually + used. Using the keyserver debug option as in + + gpg --keyserver-options debug=1 -v --refresh-key 1E42B367 + + is thus often helpful. Note that the actual output depends on the + backend and may change from release to release. + + * Logging on WindowsCE + + For development, the best logging method on WindowsCE is the use of + remote debugging using a log file name of 'tcp://:'. + The command 'watchgnupg' may be used on the remote host to listen + on the given port (*note option watchgnupg --tcp::). For in the + field tests it is better to make use of the logging facility + provided by the 'gpgcedev' driver (part of libassuan); this is + enabled by using a log file name of 'GPG2:' (*note option + --log-file::). + + +File: gnupg.info, Node: Common Problems, Next: Architecture Details, Prev: Debugging Hints, Up: Debugging + +13.3 Commonly Seen Problems +=========================== + + * Error code 'Not supported' from Dirmngr + + Most likely the option 'enable-ocsp' is active for gpgsm but + Dirmngr's OCSP feature has not been enabled using 'allow-ocsp' in + 'dirmngr.conf'. + + * The Curses based Pinentry does not work + + The far most common reason for this is that the environment + variable 'GPG_TTY' has not been set correctly. Make sure that it + has been set to a real tty device and not just to '/dev/tty'; i.e. + 'GPG_TTY=tty' is plainly wrong; what you want is 'GPG_TTY=`tty`' -- + note the back ticks. Also make sure that this environment variable + gets exported, that is you should follow up the setting with an + 'export GPG_TTY' (assuming a Bourne style shell). Even for GUI + based Pinentries; you should have set 'GPG_TTY'. See the section + on installing the 'gpg-agent' on how to do it. + + * SSH hangs while a popping up pinentry was expected + + SSH has no way to tell the gpg-agent what terminal or X display it + is running on. So when remotely logging into a box where a + gpg-agent with SSH support is running, the pinentry will get popped + up on whatever display the gpg-agent has been started. To solve + this problem you may issue the command + + echo UPDATESTARTUPTTY | gpg-connect-agent + + and the next pinentry will pop up on your display or screen. + However, you need to kill the running pinentry first because only + one pinentry may be running at once. If you plan to use ssh on a + new display you should issue the above command before invoking ssh + or any other service making use of ssh. + + * Exporting a secret key without a certificate + + It may happen that you have created a certificate request using + 'gpgsm' but not yet received and imported the certificate from the + CA. However, you want to export the secret key to another machine + right now to import the certificate over there then. You can do + this with a little trick but it requires that you know the + approximate time you created the signing request. By running the + command + + ls -ltr ~/.gnupg/private-keys-v1.d + + you get a listing of all private keys under control of 'gpg-agent'. + Pick the key which best matches the creation time and run the + command + + /usr/local/libexec/gpg-protect-tool --p12-export \ + ~/.gnupg/private-keys-v1.d/FOO >FOO.p12 + + (Please adjust the path to 'gpg-protect-tool' to the appropriate + location). FOO is the name of the key file you picked (it should + have the suffix '.key'). A Pinentry box will pop up and ask you + for the current passphrase of the key and a new passphrase to + protect it in the pkcs#12 file. + + To import the created file on the machine you use this command: + + /usr/local/libexec/gpg-protect-tool --p12-import --store FOO.p12 + + You will be asked for the pkcs#12 passphrase and a new passphrase + to protect the imported private key at its new location. + + Note that there is no easy way to match existing certificates with + stored private keys because some private keys are used for Secure + Shell or other purposes and don't have a corresponding certificate. + + * A root certificate does not verify + + A common problem is that the root certificate misses the required + basicConstraints attribute and thus 'gpgsm' rejects this + certificate. An error message indicating "no value" is a sign for + such a certificate. You may use the 'relax' flag in + 'trustlist.txt' to accept the certificate anyway. Note that the + fingerprint and this flag may only be added manually to + 'trustlist.txt'. + + * Error message: "digest algorithm N has not been enabled" + + The signature is broken. You may try the option + '--extra-digest-algo SHA256' to workaround the problem. The number + N is the internal algorithm identifier; for example 8 refers to + SHA-256. + + * The Windows version does not work under Wine + + When running the W32 version of 'gpg' under Wine you may get an + error messages like: + + gpg: fatal: WriteConsole failed: Access denied + + The solution is to use the command 'wineconsole'. + + Some operations like '--generate-key' really want to talk to the + console directly for increased security (for example to prevent the + passphrase from appearing on the screen). So, you should use + 'wineconsole' instead of 'wine', which will launch a windows + console that implements those additional features. + + * Why does GPG's -search-key list weird keys? + + For performance reasons the keyservers do not check the keys the + same way 'gpg' does. It may happen that the listing of keys + available on the keyservers shows keys with wrong user IDs or with + user Ids from other keys. If you try to import this key, the bad + keys or bad user ids won't get imported, though. This is a bit + unfortunate but we can't do anything about it without actually + downloading the keys. + + +File: gnupg.info, Node: Architecture Details, Prev: Common Problems, Up: Debugging + +13.4 How the whole thing works internally +========================================= + +* Menu: + +* Component interaction:: How the components work together. +* GnuPG-1 and GnuPG-2:: Relationship between GnuPG 1.4 and 2.x. + + +File: gnupg.info, Node: Component interaction, Next: GnuPG-1 and GnuPG-2, Up: Architecture Details + +13.4.1 How the components work together +--------------------------------------- + + [image src="gnupg-module-overview.png" alt="GnuPG modules"] + +Figure 13.1: GnuPG module overview + + +File: gnupg.info, Node: GnuPG-1 and GnuPG-2, Prev: Component interaction, Up: Architecture Details + +13.4.2 Relationship between GnuPG 1.4 and 2.x +--------------------------------------------- + +Here is a little picture showing how the different GnuPG versions make +use of a smartcard: + +[image src="gnupg-card-architecture.png" alt="GnuPG card architecture"] + +Figure 13.2: GnuPG card architecture + + +File: gnupg.info, Node: Copying, Next: Contributors, Prev: Debugging, Up: Top + +GNU General Public License +************************** + + Version 3, 29 June 2007 + + Copyright (C) 2007 Free Software Foundation, Inc. + + Everyone is permitted to copy and distribute verbatim copies of this + license document, but changing it is not allowed. + +Preamble +======== + +The GNU General Public License is a free, copyleft license for software +and other kinds of works. + + The licenses for most software and other practical works are designed +to take away your freedom to share and change the works.

Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + + To protect your rights, we need to prevent others from denying you +these rights or asking you to surrender the rights. Therefore, you have +certain responsibilities if you distribute copies of the software, or if +you modify it: responsibilities to respect the freedom of others. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must pass on to the recipients the same +freedoms that you received. You must make sure that they, too, receive +or can get the source code.

For both users' and +authors' sake, the GPL requires that modified versions be marked as +changed, so that their problems will not be attributed erroneously to +authors of previous versions. + + Some devices are designed to deny users access to install or run +modified versions of the software inside them, although the manufacturer +can do so. This is fundamentally incompatible with the aim of +protecting users' freedom to change the software.

A "Major Component", in this context, means a major + essential component (kernel, window system, and so on) of the + specific operating system (if any) on which the executable work + runs, or a compiler used to produce the work, or an object code + interpreter used to run it. + + The "Corresponding Source" for a work in object code form means all + the source code needed to generate, install, and (for an executable + work) run the object code and to modify the work, including scripts + to control those activities. However, it does not include the + work's System Libraries, or general-purpose tools or generally + available free programs which are used unmodified in performing + those activities but which are not part of the work. For example, + Corresponding Source includes interface definition files associated + with source files for the work, and the source code for shared + libraries and dynamically linked subprograms that the work is + specifically designed to require, such as by intimate data + communication or control flow between those subprograms and other + parts of the work. + + The Corresponding Source need not include anything that users can + regenerate automatically from other parts of the Corresponding + Source. + + The Corresponding Source for a work in source code form is that + same work. + + 2. Basic Permissions. + + All rights granted under this License are granted for the term of + copyright on the Program, and are irrevocable provided the stated + conditions are met. This License explicitly affirms your unlimited + permission to run the unmodified Program. The output from running + a covered work is covered by this License only if the output, given + its content, constitutes a covered work. This License acknowledges + your rights of fair use or other equivalent, as provided by + copyright law. + + You may make, run and propagate covered works that you do not + convey, without conditions so long as your license otherwise + remains in force. You may convey covered works to others for the + sole purpose of having them make modifications exclusively for you, + or provide you with facilities for running those works, provided + that you comply with the terms of this License in conveying all + material for which you do not control copyright. Those thus making + or running the covered works for you must do so exclusively on your + behalf, under your direction and control, on terms that prohibit + them from making any copies of your copyrighted material outside + their relationship with you. + + Conveying under any other circumstances is permitted solely under + the conditions stated below. Sublicensing is not allowed; section + 10 makes it unnecessary. + + 3. Protecting Users' Legal Rights From Anti-Circumvention Law. + + No covered work shall be deemed part of an effective technological + measure under any applicable law fulfilling obligations under + article 11 of the WIPO copyright treaty adopted on 20 December + 1996, or similar laws prohibiting or restricting circumvention of + such measures. + + When you convey a covered work, you waive any legal power to forbid + circumvention of technological measures to the extent such + circumvention is effected by exercising rights under this License + with respect to the covered work, and you disclaim any intention to + limit operation or modification of the work as a means of + enforcing, against the work's users, your or third parties' legal + rights to forbid circumvention of technological measures. + + 4. Conveying Verbatim Copies. + + You may convey verbatim copies of the Program's source code as you + receive it, in any medium, provided that you conspicuously and + appropriately publish on each copy an appropriate copyright notice; + keep intact all notices stating that this License and any + non-permissive terms added in accord with section 7 apply to the + code; keep intact all notices of the absence of any warranty; and + give all recipients a copy of this License along with the Program. + + You may charge any price or no price for each copy that you convey, + and you may offer support or warranty protection for a fee. + + 5. Conveying Modified Source Versions. + + You may convey a work based on the Program, or the modifications to + produce it from the Program, in the form of source code under the + terms of section 4, provided that you also meet all of these + conditions: + + a. The work must carry prominent notices stating that you + modified it, and giving a relevant date. + + b. The work must carry prominent notices stating that it is + released under this License and any conditions added under + section 7. This requirement modifies the requirement in + section 4 to "keep intact all notices". + + c. You must license the entire work, as a whole, under this + License to anyone who comes into possession of a copy. This + License will therefore apply, along with any applicable + section 7 additional terms, to the whole of the work, and all + its parts, regardless of how they are packaged. This License + gives no permission to license the work in any other way, but + it does not invalidate such permission if you have separately + received it. + + d. If the work has interactive user interfaces, each must display + Appropriate Legal Notices; however, if the Program has + interactive interfaces that do not display Appropriate Legal + Notices, your work need not make them do so. + + A compilation of a covered work with other separate and independent + works, which are not by their nature extensions of the covered + work, and which are not combined with it such as to form a larger + program, in or on a volume of a storage or distribution medium, is + called an "aggregate" if the compilation and its resulting + copyright are not used to limit the access or legal rights of the + compilation's users beyond what the individual works permit. + Inclusion of a covered work in an aggregate does not cause this + License to apply to the other parts of the aggregate. + + 6. Conveying Non-Source Forms. + + You may convey a covered work in object code form under the terms + of sections 4 and 5, provided that you also convey the + machine-readable Corresponding Source under the terms of this + License, in one of these ways: + + a. Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by the + Corresponding Source fixed on a durable physical medium + customarily used for software interchange. + + b. Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by a + written offer, valid for at least three years and valid for as + long as you offer spare parts or customer support for that + product model, to give anyone who possesses the object code + either (1) a copy of the Corresponding Source for all the + software in the product that is covered by this License, on a + durable physical medium customarily used for software + interchange, for a price no more than your reasonable cost of + physically performing this conveying of source, or (2) access + to copy the Corresponding Source from a network server at no + charge. + + c. Convey individual copies of the object code with a copy of the + written offer to provide the Corresponding Source. This + alternative is allowed only occasionally and noncommercially, + and only if you received the object code with such an offer, + in accord with subsection 6b. + + d. Convey the object code by offering access from a designated + place (gratis or for a charge), and offer equivalent access to + the Corresponding Source in the same way through the same + place at no further charge. You need not require recipients + to copy the Corresponding Source along with the object code. + If the place to copy the object code is a network server, the + Corresponding Source may be on a different server (operated by + you or a third party) that supports equivalent copying + facilities, provided you maintain clear directions next to the + object code saying where to find the Corresponding Source. + Regardless of what server hosts the Corresponding Source, you + remain obligated to ensure that it is available for as long as + needed to satisfy these requirements. + + e. Convey the object code using peer-to-peer transmission, + provided you inform other peers where the object code and + Corresponding Source of the work are being offered to the + general public at no charge under subsection 6d. + + A separable portion of the object code, whose source code is + excluded from the Corresponding Source as a System Library, need + not be included in conveying the object code work. + + A "User Product" is either (1) a "consumer product", which means + any tangible personal property which is normally used for personal, + family, or household purposes, or (2) anything designed or sold for + incorporation into a dwelling. In determining whether a product is + a consumer product, doubtful cases shall be resolved in favor of + coverage. For a particular product received by a particular user, + "normally used" refers to a typical or common use of that class of + product, regardless of the status of the particular user or of the + way in which the particular user actually uses, or expects or is + expected to use, the product. A product is a consumer product + regardless of whether the product has substantial commercial, + industrial or non-consumer uses, unless such uses represent the + only significant mode of use of the product. + + "Installation Information" for a User Product means any methods, + procedures, authorization keys, or other information required to + install and execute modified versions of a covered work in that + User Product from a modified version of its Corresponding Source. + The information must suffice to ensure that the continued + functioning of the modified object code is in no case prevented or + interfered with solely because modification has been made. + + If you convey an object code work under this section in, or with, + or specifically for use in, a User Product, and the conveying + occurs as part of a transaction in which the right of possession + and use of the User Product is transferred to the recipient in + perpetuity or for a fixed term (regardless of how the transaction + is characterized), the Corresponding Source conveyed under this + section must be accompanied by the Installation Information. But + this requirement does not apply if neither you nor any third party + retains the ability to install modified object code on the User + Product (for example, the work has been installed in ROM). + + The requirement to provide Installation Information does not + include a requirement to continue to provide support service, + warranty, or updates for a work that has been modified or installed + by the recipient, or for the User Product in which it has been + modified or installed. Access to a network may be denied when the + modification itself materially and adversely affects the operation + of the network or violates the rules and protocols for + communication across the network. + + Corresponding Source conveyed, and Installation Information + provided, in accord with this section must be in a format that is + publicly documented (and with an implementation available to the + public in source code form), and must require no special password + or key for unpacking, reading or copying. + + 7. Additional Terms. + + "Additional permissions" are terms that supplement the terms of + this License by making exceptions from one or more of its + conditions. Additional permissions that are applicable to the + entire Program shall be treated as though they were included in + this License, to the extent that they are valid under applicable + law. If additional permissions apply only to part of the Program, + that part may be used separately under those permissions, but the + entire Program remains governed by this License without regard to + the additional permissions. + + When you convey a copy of a covered work, you may at your option + remove any additional permissions from that copy, or from any part + of it. (Additional permissions may be written to require their own + removal in certain cases when you modify the work.) You may place + additional permissions on material, added by you to a covered work, + for which you have or can give appropriate copyright permission. + + Notwithstanding any other provision of this License, for material + you add to a covered work, you may (if authorized by the copyright + holders of that material) supplement the terms of this License with + terms: + + a. Disclaiming warranty or limiting liability differently from + the terms of sections 15 and 16 of this License; or + + b. Requiring preservation of specified reasonable legal notices + or author attributions in that material or in the Appropriate + Legal Notices displayed by works containing it; or + + c. Prohibiting misrepresentation of the origin of that material, + or requiring that modified versions of such material be marked + in reasonable ways as different from the original version; or + + d. Limiting the use for publicity purposes of names of licensors + or authors of the material; or + + e. Declining to grant rights under trademark law for use of some + trade names, trademarks, or service marks; or + + f. Requiring indemnification of licensors and authors of that + material by anyone who conveys the material (or modified + versions of it) with contractual assumptions of liability to + the recipient, for any liability that these contractual + assumptions directly impose on those licensors and authors. + + All other non-permissive additional terms are considered "further + restrictions" within the meaning of section 10. If the Program as + you received it, or any part of it, contains a notice stating that + it is governed by this License along with a term that is a further + restriction, you may remove that term. If a license document + contains a further restriction but permits relicensing or conveying + under this License, you may add to a covered work material governed + by the terms of that license document, provided that the further + restriction does not survive such relicensing or conveying. + + If you add terms to a covered work in accord with this section, you + must place, in the relevant source files, a statement of the + additional terms that apply to those files, or a notice indicating + where to find the applicable terms. + + Additional terms, permissive or non-permissive, may be stated in + the form of a separately written license, or stated as exceptions; + the above requirements apply either way. + + 8. Termination. + + You may not propagate or modify a covered work except as expressly + provided under this License. Any attempt otherwise to propagate or + modify it is void, and will automatically terminate your rights + under this License (including any patent licenses granted under the + third paragraph of section 11). + + However, if you cease all violation of this License, then your + license from a particular copyright holder is reinstated (a) + provisionally, unless and until the copyright holder explicitly and + finally terminates your license, and (b) permanently, if the + copyright holder fails to notify you of the violation by some + reasonable means prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is + reinstated permanently if the copyright holder notifies you of the + violation by some reasonable means, this is the first time you have + received notice of violation of this License (for any work) from + that copyright holder, and you cure the violation prior to 30 days + after your receipt of the notice. + + Termination of your rights under this section does not terminate + the licenses of parties who have received copies or rights from you + under this License. If your rights have been terminated and not + permanently reinstated, you do not qualify to receive new licenses + for the same material under section 10. + + 9. Acceptance Not Required for Having Copies. + + You are not required to accept this License in order to receive or + run a copy of the Program. Ancillary propagation of a covered work + occurring solely as a consequence of using peer-to-peer + transmission to receive a copy likewise does not require + acceptance. However, nothing other than this License grants you + permission to propagate or modify any covered work. These actions + infringe copyright if you do not accept this License. Therefore, + by modifying or propagating a covered work, you indicate your + acceptance of this License to do so. + + 10. Automatic Licensing of Downstream Recipients. + + Each time you convey a covered work, the recipient automatically + receives a license from the original licensors, to run, modify and + propagate that work, subject to this License. You are not + responsible for enforcing compliance by third parties with this + License. + + An "entity transaction" is a transaction transferring control of an + organization, or substantially all assets of one, or subdividing an + organization, or merging organizations. If propagation of a + covered work results from an entity transaction, each party to that + transaction who receives a copy of the work also receives whatever + licenses to the work the party's predecessor in interest had or + could give under the previous paragraph, plus a right to possession + of the Corresponding Source of the work from the predecessor in + interest, if the predecessor has it or can get it with reasonable + efforts. + + You may not impose any further restrictions on the exercise of the + rights granted or affirmed under this License. For example, you + may not impose a license fee, royalty, or other charge for exercise + of rights granted under this License, and you may not initiate + litigation (including a cross-claim or counterclaim in a lawsuit) + alleging that any patent claim is infringed by making, using, + selling, offering for sale, or importing the Program or any portion + of it. + + 11. Patents. + + A "contributor" is a copyright holder who authorizes use under this + License of the Program or a work on which the Program is based. + The work thus licensed is called the contributor's "contributor + version". + + A contributor's "essential patent claims" are all patent claims + owned or controlled by the contributor, whether already acquired or + hereafter acquired, that would be infringed by some manner, + permitted by this License, of making, using, or selling its + contributor version, but do not include claims that would be + infringed only as a consequence of further modification of the + contributor version. For purposes of this definition, "control" + includes the right to grant patent sublicenses in a manner + consistent with the requirements of this License. + + Each contributor grants you a non-exclusive, worldwide, + royalty-free patent license under the contributor's essential + patent claims, to make, use, sell, offer for sale, import and + otherwise run, modify and propagate the contents of its contributor + version. + + In the following three paragraphs, a "patent license" is any + express agreement or commitment, however denominated, not to + enforce a patent (such as an express permission to practice a + patent or covenant not to sue for patent infringement). To "grant" + such a patent license to a party means to make such an agreement or + commitment not to enforce a patent against the party. + + If you convey a covered work, knowingly relying on a patent + license, and the Corresponding Source of the work is not available + for anyone to copy, free of charge and under the terms of this + License, through a publicly available network server or other + readily accessible means, then you must either (1) cause the + Corresponding Source to be so available, or (2) arrange to deprive + yourself of the benefit of the patent license for this particular + work, or (3) arrange, in a manner consistent with the requirements + of this License, to extend the patent license to downstream + recipients. "Knowingly relying" means you have actual knowledge + that, but for the patent license, your conveying the covered work + in a country, or your recipient's use of the covered work in a + country, would infringe one or more identifiable patents in that + country that you have reason to believe are valid. + + If, pursuant to or in connection with a single transaction or + arrangement, you convey, or propagate by procuring conveyance of, a + covered work, and grant a patent license to some of the parties + receiving the covered work authorizing them to use, propagate, + modify or convey a specific copy of the covered work, then the + patent license you grant is automatically extended to all + recipients of the covered work and works based on it. + + A patent license is "discriminatory" if it does not include within + the scope of its coverage, prohibits the exercise of, or is + conditioned on the non-exercise of one or more of the rights that + are specifically granted under this License. You may not convey a + covered work if you are a party to an arrangement with a third + party that is in the business of distributing software, under which + you make payment to the third party based on the extent of your + activity of conveying the work, and under which the third party + grants, to any of the parties who would receive the covered work + from you, a discriminatory patent license (a) in connection with + copies of the covered work conveyed by you (or copies made from + those copies), or (b) primarily for and in connection with specific + products or compilations that contain the covered work, unless you + entered into that arrangement, or that patent license was granted, + prior to 28 March 2007. + + Nothing in this License shall be construed as excluding or limiting + any implied license or other defenses to infringement that may + otherwise be available to you under applicable patent law. + + 12. No Surrender of Others' Freedom. + + If conditions are imposed on you (whether by court order, agreement + or otherwise) that contradict the conditions of this License, they + do not excuse you from the conditions of this License. If you + cannot convey a covered work so as to satisfy simultaneously your + obligations under this License and any other pertinent obligations, + then as a consequence you may not convey it at all. For example, + if you agree to terms that obligate you to collect a royalty for + further conveying from those to whom you convey the Program, the + only way you could satisfy both those terms and this License would + be to refrain entirely from conveying the Program. + + 13. Use with the GNU Affero General Public License. + + Notwithstanding any other provision of this License, you have + permission to link or combine any covered work with a work licensed + under version 3 of the GNU Affero General Public License into a + single combined work, and to convey the resulting work. The terms + of this License will continue to apply to the part which is the + covered work, but the special requirements of the GNU Affero + General Public License, section 13, concerning interaction through + a network will apply to the combination as such. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new + versions of the GNU General Public License from time to time. Such + new versions will be similar in spirit to the present version, but + may differ in detail to address new problems or concerns. + + Each version is given a distinguishing version number. If the + Program specifies that a certain numbered version of the GNU + General Public License "or any later version" applies to it, you + have the option of following the terms and conditions either of + that numbered version or of any later version published by the Free + Software Foundation. If the Program does not specify a version + number of the GNU General Public License, you may choose any + version ever published by the Free Software Foundation. + + If the Program specifies that a proxy can decide which future + versions of the GNU General Public License can be used, that + proxy's public statement of acceptance of a version permanently + authorizes you to choose that version for the Program. + + Later license versions may give you additional or different + permissions. However, no additional obligations are imposed on any + author or copyright holder as a result of your choosing to follow a + later version. + + 15. Disclaimer of Warranty. + + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY + APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE + COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" + WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, + INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF + MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE + RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. + SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL + NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. Limitation of Liability. + + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN + WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES + AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR + DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR + CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE + THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA + BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD + PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER + PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF + THE POSSIBILITY OF SUCH DAMAGES. + + 17. Interpretation of Sections 15 and 16. + + If the disclaimer of warranty and limitation of liability provided + above cannot be given local legal effect according to their terms, + reviewing courts shall apply local law that most closely + approximates an absolute waiver of all civil liability in + connection with the Program, unless a warranty or assumption of + liability accompanies a copy of the Program in return for a fee. + + END OF TERMS AND CONDITIONS + +How to Apply These Terms to Your New Programs +============================================= + +If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these +terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +state the exclusion of warranty; and each file should have at least the +"copyright" line and a pointer to where the full notice is found. + + ONE LINE TO GIVE THE PROGRAM'S NAME AND A BRIEF IDEA OF WHAT IT DOES. + Copyright (C) YEAR NAME OF AUTHOR + + This program is free software: you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation, either version 3 of the License, or (at + your option) any later version. + + This program is distributed in the hope that it will be useful, but + WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU + General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program. If not, see . + +Also add information on how to contact you by electronic and paper mail. + +If the program does terminal interaction, make it output a short notice +like this when it starts in an interactive mode: + + PROGRAM Copyright (C) YEAR NAME OF AUTHOR + This program comes with ABSOLUTELY NO WARRANTY; for details + type 'show w'. This is free software, and you are + welcome to redistribute it under certain conditions; + type 'show c' for details. + + The hypothetical commands 'show w' and 'show c' should show the +appropriate parts of the General Public License. Of course, your +program's commands might be different; for a GUI interface, you would +use an "about box". + + You should also get your employer (if you work as a programmer) or +school, if any, to sign a "copyright disclaimer" for the program, if +necessary. For more information on this, and how to apply and follow +the GNU GPL, see . + + The GNU General Public License does not permit incorporating your +program into proprietary programs. If your program is a subroutine +library, you may consider it more useful to permit linking proprietary +applications with the library. If this is what you want to do, use the +GNU Lesser General Public License instead of this License. But first, +please read . + + +File: gnupg.info, Node: Contributors, Next: Glossary, Prev: Copying, Up: Top + +Contributors to GnuPG +********************* + +The GnuPG project would like to thank its many contributors.

This allows the verification of signatures + after the CA's certificate expired. The validation test also + required an online check of the certificate status. The chain + model is required by the German signature law. See also _Shell + model_. + +'CMS' + The _Cryptographic Message Standard_ describes a message format for + encryption and digital signing. It is closely related to the X.509 + certificate format. CMS was formerly known under the name 'PKCS#7' + and is described by 'RFC3369'. + +'CRL' + The _Certificate Revocation List_ is a list containing certificates + revoked by the issuer. + +'CSR' + The _Certificate Signing Request_ is a message send to a CA to ask + them to issue a new certificate. The data format of such a signing + request is called PCKS#10. + +'OpenPGP' + A data format used to build a PKI and to exchange encrypted or + signed messages. In contrast to X.509, OpenPGP also includes the + message format but does not explicitly demand a specific PKI. + However any kind of PKI may be build upon the OpenPGP protocol. + +'Keygrip' + This term is used by GnuPG to describe a 20 byte hash value used to + identify a certain key without referencing to a concrete protocol. + It is used internally to access a private key. Usually it is shown + and entered as a 40 character hexadecimal formatted string. + +'OCSP' + The _Online Certificate Status Protocol_ is used as an alternative + to a CRL. It is described in 'RFC 2560'. + +'PSE' + The _Personal Security Environment_ describes a database to store + private keys. This is either a smartcard or a collection of files + on a disk; the latter is often called a Soft-PSE. + +'Shell model' + The standard model for validation of certificates under X.509. At + the time of the verification all certificates must be valid and not + expired. See also _Chain model_. + +'X.509' + Description of a PKI used with CMS. It is for example defined by + 'RFC3280'. + + +File: gnupg.info, Node: Option Index, Next: Environment Index, Prev: Glossary, Up: Top + +Option Index +************ + +[index] +* Menu: + +* add-servers: Dirmngr Options.
