TSIG algorithm can be specified by string (default: hmac-sha256), + bit length of the key by number (default: optimal length given by algorithm). The generated + TSIG key is only displayed on `stdout`: the command does not create a file, nor include the + key in a keystore. + +Config options +.............. + +**-c**, **--config** *file* + Use a textual configuration file (default is :file:`@config_dir@/knot.conf`). + +**-C**, **--confdb** *directory* + Use a binary configuration database directory (default is :file:`@storage_dir@/confdb`). + The default configuration database, if exists, has a preference to the default + configuration file. + +**-d**, **--dir** *path* + Use specified KASP database path and default configuration. + +Commands +........ + +**list** [*timestamp_format*] + Prints the list of key IDs and parameters of keys belonging to the zone. + +**generate** [*arguments*...] + Generates new DNSSEC key and stores it in KASP database. Prints the key ID. + This action takes some number of arguments (see below). Values for unspecified arguments are taken + from corresponding policy (if *-c* or *-C* options used) or from Knot policy defaults. + +**import-bind** *BIND_key_file* + Imports a BIND-style key into KASP database (converting it to PEM format). + Takes one argument: path to BIND key file (private or public, but both MUST exist). + +**import-pub** *BIND_pubkey_file* + Imports a public key into KASP database. This key won't be rollovered nor used for signing. + Takes one argument: path to BIND public key file. + +**import-pem** *PEM_file* [*arguments*...] + Imports a DNSSEC key from PEM file. The key parameters (same as for the generate action) need to be + specified (mainly algorithm, timers...) because they are not contained in the PEM format. + +**import-pkcs11** *key_id* [*arguments*...] + Imports a DNSSEC key from PKCS #11 storage. The key parameters (same as for the generate action) need to be + specified (mainly algorithm, timers...) because they are not available. In fact, no key + data is imported, only KASP database metadata is created. + +**nsec3-salt** [*new_salt*] + Prints the current NSEC3 salt used for signing. If *new_salt* is specified, the salt is overwritten. + The salt is printed and expected in hexadecimal, or dash if empty. + +**set** *key_spec* [*arguments*...] + Changes a timing argument (or ksk/zsk) of an existing key to a new value. *Key_spec* is either the + key tag or a prefix of the key ID; *arguments* are like for **generate**, but just the related ones. + +**ds** [*key_spec*] + Generate DS record (all digest algorithms together) for specified key. *Key_spec* + is like for **set**, if unspecified, all KSKs are used. + +**dnskey** [*key_spec*] + Generate DNSKEY record for specified key. *Key_spec* + is like for **ds**, if unspecified, all KSKs are used. + +**delete** *key_spec* + Remove the specified key from zone. If the key was not shared, it is also deleted from keystore. + +**share** *key_ID* + Import a key (specified by full key ID) from another zone as shared. After this, the key is + owned by both zones equally. + +Generate arguments +.................. + +Arguments are separated by space, each of them is in format 'name=value'. + +**algorithm** + Either an algorithm number (e.g. 14), or text name without dashes (e.g. ECDSAP384SHA384). + +**size** + Key length in bits. + +**ksk** + If set to **yes**, the key will be used for signing DNSKEY rrset. The generated key will also + have the Secure Entry Point flag set to 1. + +**zsk** + If set to **yes**, the key will be used for signing zone (except DNSKEY rrset). This flag can + be set concurrently with the **ksk** flag. + +**sep** + Overrides the standard setting of the Secure Entry Point flag for the generated key. + +The following arguments are timestamps of key lifetime: + +**created** + Key created. + +**pre_active** + Key started to be used for signing, not published (only for algorithm rollover). + +**publish** + Key published. + +**ready** + Key used for signing and submitted to the parent zone (only for KSK). + +**active** + Key used for signing. + +**post_active** + Key still used for singing, but another key is active (only for KSK). + +**retire_active** + Key no longer published, but still used for signing (only for algorithm rollover). + +**retire** + Key still published, but no longer used for signing. + +**remove** + Key deleted. + +Timestamps +.......... + +0 + Zero timestamp means infinite future. + +*UNIX_time* + Positive number of seconds since 1970 UTC. + +*YYYYMMDDHHMMSS* + Date and time in this format without any punctuation. + +*relative_timestamp* + A sign character (**+**, **-**), a number, and an optional time unit + (**y**, **mo**, **d**, **h**, **mi**, **s**). The default unit is one second. + E.g. +1mi, -2mo. + +Output timestamp formats +........................ + +(none) + The timestamps are printed as UNIX timestamp. + +**human** + The timestamps are printed relatively to now using time units (e.g. -2y5mo, +1h13s). + +**iso** + The timestamps are printed in the ISO8601 format (e.g. 2016-12-31T23:59:00). + +Examples +-------- + +1.
