+NSS tools : modutil
+===================
+
+.. container::
+
+ | Name
+ |    modutil — Manage PKCS #11 module information within the security module
+ |    database.
+ | Synopsis
+ |    modutil [options] `arguments <arguments>`__
+ | Description
+ |    The Security Module Database Tool, modutil, is a command-line utility for
+ |    managing PKCS #11 module information both within secmod.db files and
+ |    within hardware tokens. modutil can add and delete PKCS #11 modules,
+ |    change passwords on security databases, set defaults, list module
+ |    contents, enable or disable slots, enable or disable FIPS 140-2
+ |    compliance, and assign default providers for cryptographic operations.
+ |    This tool can also create certificate, key, and module security database
+ |    files.
+ |    The tasks associated with security module database management are part of
+ |    a process that typically also involves managing key databases and
+ |    certificate databases.
+ | Options
+ |    Running modutil always requires one (and only one) option to specify the
+ |    type of module operation. Each option may take arguments, anywhere from
+ |    none to multiple arguments.
+ |    Options
+ |    -add modulename
+ |            Add the named PKCS #11 module to the database. Use this option
+ |            with the -libfile, -ciphers, and -mechanisms arguments.
+ |    -changepw tokenname
+ |            Change the password on the named token. If the token has not been
+ |            initialized, this option initializes the password. Use this option
+ |            with the -pwfile and -newpwfile arguments. A password is
+ |            equivalent to a personal identification number (PIN).
+ |    -chkfips
+ |            Verify whether the module is in the given FIPS mode. true means to
+ |            verify that the module is in FIPS mode, while false means to
+ |            verify that the module is not in FIPS mode.
+ |    -create
+ |            Create new certificate, key, and module databases. Use the -dbdir
+ |            directory argument to specify a directory. If any of these
+ |            databases already exist in a specified directory, modutil returns
+ |            an error message.
+ |    -default modulename
+ |            Specify the security mechanisms for which the named module will be
+ |            a default provider. The security mechanisms are specified with the
+ |            -mechanisms argument.
+ |    -delete modulename
+ |            Delete the named module. The default NSS PKCS #11 module cannot be
+ |            deleted.
+ |    -disable modulename
+ |            Disable all slots on the named module. Use the -slot argument to
+ |            disable a specific slot.
+ |    -enable modulename
+ |            Enable all slots on the named module. Use the -slot argument to
+ |            enable a specific slot.
+ |    -fips [true \| false]
+ |            Enable (true) or disable (false) FIPS 140-2 compliance for the
+ |            default NSS module.
+ |    -force
+ |            Disable modutil's interactive prompts so it can be run from a
+ |            script. Use this option only after manually testing each planned
+ |            operation to check for warnings and to ensure that bypassing the
+ |            prompts will cause no security lapses or loss of database
+ |            integrity.
+ |    -jar JAR-file
+ |            Add a new PKCS #11 module to the database using the named JAR
+ |            file. Use this command with the -installdir and -tempdir
+ |            arguments. The JAR file uses the NSS PKCS #11 JAR format to
+ |            identify all the files to be installed, the module's name, the
+ |            mechanism flags, and the cipher flags, as well as any files to be
+ |            installed on the target machine, including the PKCS #11 module
+ |            library file and other files such as documentation. This is
+ |            covered in the JAR installation file section in the man page,
+ |            which details the special script needed to perform an installation
+ |            through a server or with modutil.
+ |    -list [modulename]
+ |            Display basic information about the contents of the secmod.db
+ |            file. Specifying a modulename displays detailed information about
+ |            a particular module and its slots and tokens.
+ |    -rawadd
+ |            Add the module spec string to the secmod.db database.
+ |    -rawlist
+ |            Display the module specs for a specified module or for all
+ |            loadable modules.
+ |    -undefault modulename
+ |            Specify the security mechanisms for which the named module will
+ |            not be a default provider. The security mechanisms are specified
+ |            with the -mechanisms argument.
+ |    Arguments
+ |    MODULE
+ |            Give the security module to access.
+ |    MODULESPEC
+ |            Give the security module spec to load into the security database.
+ |    -ciphers cipher-enable-list
+ |            Enable specific ciphers in a module that is being added to the
+ |            database. The cipher-enable-list is a colon-delimited list of
+ |            cipher names. Enclose this list in quotation marks if it contains
+ |            spaces.
+ |    -dbdir [sql:]directory
+ |            Specify the database directory in which to access or create
+ |            security module database files.
+ |            modutil supports two types of databases: the legacy security
+ |            databases (cert8.db, key3.db, and secmod.db) and new SQLite
+ |            databases (cert9.db, key4.db, and pkcs11.txt). If the prefix sql:
+ |            is not used, then the tool assumes that the given databases are in
+ |            the old format.
+ |    --dbprefix prefix
+ |            Specify the prefix used on the database files, such as my\_ for
+ |            my_cert8.db. This option is provided as a special case. Changing
+ |            the names of the certificate and key databases is not recommended.
+ |    -installdir root-installation-directory
+ |            Specify the root installation directory relative to which files
+ |            will be installed by the -jar option. This directory should be one
+ |            below which it is appropriate to store dynamic library files, such
+ |            as a server's root directory.
+ |    -libfile library-file
+ |            Specify a path to a library file containing the implementation of
+ |            the PKCS #11 interface module that is being added to the database.
+ |    -mechanisms mechanism-list
+ |            Specify the security mechanisms for which a particular module will
+ |            be flagged as a default provider. The mechanism-list is a
+ |            colon-delimited list of mechanism names. Enclose this list in
+ |            quotation marks if it contains spaces.
+ |            The module becomes a default provider for the listed mechanisms
+ |            when those mechanisms are enabled. If more than one module claims
+ |            to be a particular mechanism's default provider, that mechanism's
+ |            default provider is undefined.
+ |            modutil supports several mechanisms: RSA, DSA, RC2, RC4, RC5, AES,
+ |            DES, DH, SHA1, SHA256, SHA512, SSL, TLS, MD5, MD2, RANDOM (for
+ |            random number generation), and FRIENDLY (meaning certificates are
+ |            publicly readable).
+ |    -newpwfile new-password-file
+ |            Specify a text file containing a token's new or replacement
+ |            password so that a password can be entered automatically with the
+ |            -changepw option.
+ |    -nocertdb
+ |            Do not open the certificate or key databases. This has several
+ |            effects:
+ |               o With the -create command, only a module security file is
+ |                 created; certificate and key databases are not created.
+ |               o With the -jar command, signatures on the JAR file are not
+ |                 checked.
+ |               o With the -changepw command, the password on the NSS internal
+ |                 module cannot be set or changed, since this password is
+ |                 stored in the key database.
+ |    -pwfile old-password-file
+ |            Specify a text file containing a token's existing password so that
+ |            a password can be entered automatically when the -changepw option
+ |            is used to change passwords.
+ |    -secmod secmodname
+ |            Give the name of the security module database (like secmod.db) to
+ |            load.
+ |    -slot slotname
+ |            Specify a particular slot to be enabled or disabled with the
+ |            -enable or -disable options.
+ |    -string CONFIG_STRING
+ |            Pass a configuration string for the module being added to the
+ |            database.
+ |    -tempdir temporary-directory
+ |            Give a directory location where temporary files are created during
+ |            the installation by the -jar option. If no temporary directory is
+ |            specified, the current directory is used.
+ | Usage and Examples
+ |    Creating Database Files
+ |    Before any operations can be performed, there must be a set of security
+ |    databases available. modutil can be used to create these files. The only
+ |    required argument is the database that where the databases will be
+ |    located.
+ |  modutil -create -dbdir [sql:]directory
+ |    Adding a Cryptographic Module
+ |    Adding a PKCS #11 module means submitting a supporting library file,
+ |    enabling its ciphers, and setting default provider status for various
+ |    security mechanisms. This can be done by supplying all of the information
+ |    through modutil directly or by running a JAR file and install script. For
+ |    the most basic case, simply upload the library:
+ |  modutil -add modulename -libfile library-file [-ciphers cipher-enable-list] [-mechanisms
+ mechanism-list]
+ |    For example:
+ |  modutil -dbdir sql:/home/my/sharednssdb -add "Example PKCS #11 Module" -libfile
+ "/tmp/crypto.so" -mechanisms RSA:DSA:RC2:RANDOM
+ |  Using database directory ...
+ |  Module "Example PKCS #11 Module" added to database.
+ |    Installing a Cryptographic Module from a JAR File
+ |    PKCS #11 modules can also be loaded using a JAR file, which contains all
+ |    of the required libraries and an installation script that describes how to
+ |    install the module. The JAR install script is described in more detail in
+ |    [1]the section called “JAR Installation File Format”.
+ |    The JAR installation script defines the setup information for each
+ |    platform that the module can be installed on. For example:
+ |  Platforms {
+ |     Linux:5.4.08:x86 {
+ |        ModuleName { "Example PKCS #11 Module" }
+ |        ModuleFile { crypto.so }
+ |        DefaultMechanismFlags{0x0000}
+ |        CipherEnableFlags{0x0000}
+ |        Files {
+ |           crypto.so {
+ |              Path{ /tmp/crypto.so }
+ |           }
+ |           setup.sh {
+ |              Executable
+ |              Path{ /tmp/setup.sh }
+ |           }
+ |        }
+ |     }
+ |     Linux:6.0.0:x86 {
+ |        EquivalentPlatform { Linux:5.4.08:x86 }
+ |     }
+ |  }
+ |    Both the install script and the required libraries must be bundled in a
+ |    JAR file, which is specified with the -jar argument.
+ |  modutil -dbdir sql:/home/mt"jar-install-filey/sharednssdb -jar install.jar -installdir
+ sql:/home/my/sharednssdb

+ |    Adding Module Spec
+ |    Each module has information stored in the security database about its
+ |    configuration and parameters. These can be added or edited using the
+ |    -rawadd command. For the current settings or to see the format of the
+ |    module spec in the database, use the -rawlist option.
+ |  modutil -rawadd modulespec
+ |    Deleting a Module
+ |    A specific PKCS #11 module can be deleted from the secmod.db database:
+ |  modutil -delete modulename -dbdir [sql:]directory
+ |    Displaying Module Information
+ |    The secmod.db database contains information about the PKCS #11 modules
+ |    that are available to an application or server to use. The list of all
+ |    modules, information about specific modules, and database configuration
+ |    specs for modules can all be viewed.
+ |    To simply get a list of modules in the database, use the -list command.
+ |  modutil -list [modulename] -dbdir [sql:]directory
+ |    Listing the modules shows the module name, their status, and other
+ |    associated security databases for certificates and keys. For example:
+ |  modutil -list -dbdir sql:/home/my/sharednssdb
+ |  Listing of PKCS #11 Modules

+ |    Setting a Default Provider for Security Mechanisms
+ |    Multiple security modules may provide support for the same security
+ |    mechanisms. It is possible to set a specific security module as the
+ |    default provider for a specific security mechanism (or, conversely, to
+ |    prohibit a provider from supplying those mechanisms).
+ |  modutil -default modulename -mechanisms mechanism-list
+ |    To set a module as the default provider for mechanisms, use the -default
+ |    command with a colon-separated list of mechanisms. The available
+ |    mechanisms depend on the module; NSS supplies almost all common
+ |    mechanisms. For example:
+ |  modutil -default "NSS Internal PKCS #11 Module" -dbdir -mechanisms RSA:DSA:RC2
+ |  Using database directory c:\databases...
+ |  Successfully changed defaults.
+ |    Clearing the default provider has the same format:
+ |  modutil -undefault "NSS Internal PKCS #11 Module" -dbdir -mechanisms MD2:MD5
+ |    Enabling and Disabling Modules and Slots
+ |    Modules, and specific slots on modules, can be selectively enabled or
+ |    disabled using modutil. Both commands have the same format:
+ |  modutil -enable|-disable modulename [-slot slotname]
+ |    For example:
+ |  modutil -enable "NSS Internal PKCS #11 Module" -slot "NSS Internal Cryptographic
+ Services                            " -dbdir .
+ |  Slot "NSS Internal Cryptographic Services                            " enabled.
+ |    Be sure that the appropriate amount of trailing whitespace is after the
+ |    slot name. Some slot names have a significant amount of whitespace that
+ |    must be included, or the operation will fail.
+ |    Enabling and Verifying FIPS Compliance
+ |    The NSS modules can have FIPS 140-2 compliance enabled or disabled using
+ |    modutil with the -fips option. For example:
+ |  modutil -fips true -dbdir sql:/home/my/sharednssdb/
+ |  FIPS mode enabled.
+ |    To verify that status of FIPS mode, run the -chkfips command with either a
+ |    true or false flag (it doesn't matter which). The tool returns the current
+ |    FIPS setting.
+ |  modutil -chkfips false -dbdir sql:/home/my/sharednssdb/
+ |  FIPS mode enabled.
+ |    Changing the Password on a Token
+ |    Initializing or changing a token's password:
+ |  modutil -changepw tokenname [-pwfile old-password-file] [-newpwfile new-password-file]
+ |  modutil -dbdir sql:/home/my/sharednssdb -changepw "NSS Certificate DB"
+ |  Enter old password:
+ |  Incorrect password, try again...
+ |  Enter old password:
+ |  Enter new password:
+ |  Re-enter new password:
+ |  Token "Communicator Certificate DB" password changed successfully.
+ | JAR Installation File Format
+ |    When a JAR file is run by a server, by modutil, or by any program that
+ |    does not interpret JavaScript, a special information file must be included
+ |    to install the libraries. There are several things to keep in mind with
+ |    this file:
+ |      o It must be declared in the JAR archive's manifest file.
+ |      o The script can have any name.
+ |      o The metainfo tag for this is Pkcs11_install_script. To declare
+ |        meta-information in the manifest file, put it in a file that is passed
+ |        to signtool.
+ |    Sample Script
+ |    For example, the PKCS #11 installer script could be in the file
+ |    pk11install. If so, the metainfo file for signtool includes a line such as
+ |    this:
+ |  + Pkcs11_install_script: pk11install
+ |    The script must define the platform and version number, the module name
+ |    and file, and any optional information like supported ciphers and
+ |    mechanisms. Multiple platforms can be defined in a single install file.

+ |    Script Grammar
+ |    The script is basic Java, allowing lists, key-value pairs, strings, and
+ |    combinations of all of them.
+ |  --> valuelist
+ |  valuelist --> value valuelist
+ |                 <null>
+ |  value ---> key_value_pair
+ |              string
+ |  key_value_pair --> key { valuelist }
+ |  key --> string
+ |  string --> simple_string
+ |              "complex_string"
+ |  simple_string --> [^ \\t\n\""{""}"]+
+ |  complex_string --> ([^\"\\\r\n]|(\\\")|(\\\\))+
+ |    Quotes and backslashes must be escaped with a backslash. A complex string
+ |    must not include newlines or carriage returns.Outside of complex strings,
+ |    all white space (for example, spaces, tabs, and carriage returns) is
+ |    considered equal and is used only to delimit tokens.
+ |    Keys
+ |    The Java install file uses keys to define the platform and module
+ |    information.
+ |    ForwardCompatible gives a list of platforms that are forward compatible.
+ |    If the current platform cannot be found in the list of supported
+ |    platforms, then the ForwardCompatible list is checked for any platforms
+ |    that have the same OS and architecture in an earlier version. If one is
+ |    found, its attributes are used for the current platform.
+ |    Platforms (required) Gives a list of platforms. Each entry in the list is
+ |    itself a key-value pair: the key is the name of the platform and the value
+ |    list contains various attributes of the platform. The platform string is
+ |    in the format system name:OS release:architecture. The installer obtains
+ |    these values from NSPR. OS release is an empty string on non-Unix
+ |    operating systems. NSPR supports these platforms:
+ |      o AIX (rs6000)
+ |      o BSDI (x86)
+ |      o FREEBSD (x86)
+ |      o HPUX (hppa1.1)
+ |      o IRIX (mips)
+ |      o LINUX (ppc, alpha, x86)
+ |      o MacOS (PowerPC)
+ |      o NCR (x86)
+ |      o NEC (mips)
+ |      o OS2 (x86)
+ |      o OSF (alpha)
+ |      o ReliantUNIX (mips)
+ |      o SCO (x86)
+ |      o SOLARIS (sparc)
+ |      o SONY (mips)
+ |      o SUNOS (sparc)
+ |      o UnixWare (x86)
+ |      o WIN16 (x86)
+ |      o WIN95 (x86)
+ |      o WINNT (x86)
+ |    For example:
+ |  IRIX:6.2:mips
+ |  SUNOS:5.5.1:sparc

+ |    The module information is defined independently for each platform in the
+ |    ModuleName, ModuleFile, and Files attributes. These attributes must be
+ |    given unless an EquivalentPlatform attribute is specified.
+ |    Per-Platform Keys
+ |    Per-platform keys have meaning only within the value list of an entry in
+ |    the Platforms list.
+ |    ModuleName (required) gives the common name for the module. This name is
+ |    used to reference the module by servers and by the modutil tool.
+ |    ModuleFile (required) names the PKCS #11 module file for this platform.
+ |    The name is given as the relative path of the file within the JAR archive.
+ |    Files (required) lists the files that need to be installed for this
+ |    module. Each entry in the file list is a key-value pair. The key is the
+ |    path of the file in the JAR archive, and the value list contains
+ |    attributes of the file. At least RelativePath or AbsolutePath must be
+ |    specified for each file.
+ |    DefaultMechanismFlags specifies mechanisms for which this module is the
+ |    default provider; this is equivalent to the -mechanism option with the
+ |    -add command. This key-value pair is a bitstring specified in hexadecimal
+ |    (0x) format. It is constructed as a bitwise OR. If the
+ |    DefaultMechanismFlags entry is omitted, the value defaults to 0x0.
+ |  RSA:                   0x00000001
+ |  DSA:                   0x00000002

+ |  OWN_PW_DEFAULTS:       0x20000000
+ |  DISABLE:               0x40000000
+ |    CipherEnableFlags specifies ciphers that this module provides that NSS
+ |    does not provide (so that the module enables those ciphers for NSS). This
+ |    is equivalent to the -cipher argument with the -add command. This key is a
+ |    bitstring specified in hexadecimal (0x) format. It is constructed as a
+ |    bitwise OR. If the CipherEnableFlags entry is omitted, the value defaults
+ |    to 0x0.
+ |    EquivalentPlatform specifies that the attributes of the named platform
+ |    should also be used for the current platform. This makes it easier when
+ |    more than one platform uses the same settings.
+ |    Per-File Keys
+ |    Some keys have meaning only within the value list of an entry in a Files
+ |    list.
+ |    Each file requires a path key the identifies where the file is. Either
+ |    RelativePath or AbsolutePath must be specified. If both are specified, the
+ |    relative path is tried first, and the absolute path is used only if no
+ |    relative root directory is provided by the installer program.
+ |    RelativePath specifies the destination directory of the file, relative to
+ |    some directory decided at install time. Two variables can be used in the
+ |    relative path: %root% and %temp%. %root% is replaced at run time with the
+ |    directory relative to which files should be installed; for example, it may
+ |    be the server's root directory. The %temp% directory is created at the
+ |    beginning of the installation and destroyed at the end. The purpose of
+ |    %temp% is to hold executable files (such as setup programs) or files that
+ |    are used by these programs. Files destined for the temporary directory are
+ |    guaranteed to be in place before any executable file is run; they are not
+ |    deleted until all executable files have finished.
+ |    AbsolutePath specifies the destination directory of the file as an
+ |    absolute path.
+ |    Executable specifies that the file is to be executed during the course of
+ |    the installation. Typically, this string is used for a setup program
+ |    provided by a module vendor, such as a self-extracting setup executable.
+ |    More than one file can be specified as executable, in which case the files
+ |    are run in the order in which they are specified in the script file.
+ |    FilePermissions sets permissions on any referenced files in a string of
+ |    octal digits, according to the standard Unix format. This string is a
+ |    bitwise OR.
+ |  user read:                0400
+ |  user write:               0200
+ |  user execute:             0100
+ |  group read:               0040
+ |  group write:              0020
+ |  group execute:            0010
+ |  other read:               0004
+ |  other write:              0002
+ |  other execute:       0001
+ |    Some platforms may not understand these permissions. They are applied only
+ |    insofar as they make sense for the current platform. If this attribute is
+ |    omitted, a default of 777 is assumed.
+ | NSS Database Types
+ |    NSS originally used BerkeleyDB databases to store security information.
+ |    The last versions of these legacy databases are:
+ |      o cert8.db for certificates
+ |      o key3.db for keys
+ |      o secmod.db for PKCS #11 module information
+ |    BerkeleyDB has performance limitations, though, which prevent it from
+ |    being easily used by multiple applications simultaneously. NSS has some
+ |    flexibility that allows applications to use their own, independent
+ |    database engine while keeping a shared database and working around the
+ |    access issues. Still, NSS requires more flexibility to provide a truly
+ |    shared security database.
+ |    In 2009, NSS introduced a new set of databases that are SQLite databases
+ |    rather than BerkleyDB. These new databases provide more accessibility and
+ |    performance:
+ |      o cert9.db for certificates
+ |      o key4.db for keys
+ |      o pkcs11.txt, which is listing of all of the PKCS #11 modules contained
+ |        in a new subdirectory in the security databases directory
+ |    Because the SQLite databases are designed to be shared, these are the
+ |    shared database type. The shared database type is preferred; the legacy
+ |    format is included for backward compatibility.
+ |    By default, the tools (certutil, pk12util, modutil) assume that the given
+ |    security databases follow the more common legacy type. Using the SQLite
+ |    databases must be manually specified by using the sql: prefix with the
+ |    given security directory. For example:
+ |  modutil -create -dbdir sql:/home/my/sharednssdb
+ |    To set the shared database type as the default type for the tools, set the
+ |    NSS_DEFAULT_DB_TYPE environment variable to sql:
+ |  export NSS_DEFAULT_DB_TYPE="sql"
+ |    This line can be set added to the ~/.bashrc file to make the change
+ |    permanent.
+ |    Most applications do not use the shared database by default, but they can
+ |    be configured to use them. For example, this how-to article covers how to
+ |    configure Firefox and Thunderbird to use the new shared NSS databases:
+ |      o https://wiki.mozilla.org/NSS_Shared_DB_Howto
+ |    For an engineering draft on the changes in the shared NSS databases, see
+ |    the NSS project wiki:
