NAME

       dnssec-settime - Set the key timing metadata for a DNSSEC key

SYNOPSIS

       dnssec-settime [-f] [-K directory] [-L ttl] [-P date/offset] [-A date/offset]
                      [-R date/offset] [-I date/offset] [-D date/offset] [-h] [-V] [-v level]
                      [-E engine] {keyfile}

DESCRIPTION

       dnssec-settime reads a DNSSEC private key file and sets the key timing metadata as
       specified by the -P, -A, -R, -I, and -D options. The metadata can then be used by
       dnssec-signzone or other signing software to determine when a key is to be published,
       whether it should be used for signing a zone, etc.

       If none of these options is set on the command line, then dnssec-settime simply prints the
       key timing metadata already stored in the key.

       When key metadata fields are changed, both files of a key pair (Knnnn.+aaa+iiiii.key and
       Knnnn.+aaa+iiiii.private) are regenerated. Metadata fields are stored in the private file.
       A human-readable description of the metadata is also placed in comments in the key file.
       The private file's permissions are always set to be inaccessible to anyone other than the
       owner (mode 0600).

OPTIONS

       -f
           Force an update of an old-format key with no metadata fields. Without this option,
           dnssec-settime will fail when attempting to update a legacy key. With this option, the
           key will be recreated in the new format, but with the original key data retained. The
           key's creation date will be set to the present time. If no other values are specified,
           then the key's publication and activation dates will also be set to the present time.

       -K directory
           Sets the directory in which the key files are to reside.

       -L ttl
           Sets the default TTL to use for this key when it is converted into a DNSKEY RR. If the
           key is imported into a zone, this is the TTL that will be used for it, unless there
           was already a DNSKEY RRset in place, in which case the existing TTL would take
           precedence. If this value is not set and there is no existing DNSKEY RRset, the TTL
           will default to the SOA TTL. Setting the default TTL to 0 or none removes it from the
           key.

       -h
           Emit usage message and exit.

       -V
           Prints version information.

       -v level
           Sets the debugging level.

       -E engine
           Specifies the cryptographic hardware to use, when applicable.

           When BIND is built with OpenSSL PKCS#11 support, this defaults to the string "pkcs11",
           which identifies an OpenSSL engine that can drive a cryptographic accelerator or
           hardware service module. When BIND is built with native PKCS#11 cryptography
           (--enable-native-pkcs11), it defaults to the path of the PKCS#11 provider library
           specified via "--with-pkcs11".

TIMING OPTIONS

       Dates can be expressed in the format YYYYMMDD or YYYYMMDDHHMMSS. If the argument begins
       with a '+' or '-', it is interpreted as an offset from the present time. For convenience,
       if such an offset is followed by one of the suffixes 'y', 'mo', 'w', 'd', 'h', or 'mi',
       then the offset is computed in years (defined as 365 24-hour days, ignoring leap years),
       months (defined as 30 24-hour days), weeks, days, hours, or minutes, respectively. Without
       a suffix, the offset is computed in seconds. To unset a date, use 'none' or 'never'.

       -P date/offset
           Sets the date on which a key is to be published to the zone. After that date, the key
           will be included in the zone but will not be used to sign it.

       -A date/offset
           Sets the date on which the key is to be activated. After that date, the key will be
           included in the zone and used to sign it.

       -R date/offset
           Sets the date on which the key is to be revoked. After that date, the key will be
           flagged as revoked. It will be included in the zone and will be used to sign it.

       -I date/offset
           Sets the date on which the key is to be retired. After that date, the key will still
           be included in the zone, but it will not be used to sign it.

       -D date/offset
           Sets the date on which the key is to be deleted. After that date, the key will no
           longer be included in the zone. (It may remain in the key repository, however.)

       -S predecessor key
           Select a key for which the key being modified will be an explicit successor. The name,
           algorithm, size, and type of the predecessor key must exactly match those of the key
           being modified. The activation date of the successor key will be set to the
           inactivation date of the predecessor. The publication date will be set to the
           activation date minus the prepublication interval, which defaults to 30 days.

       -i interval
           Sets the prepublication interval for a key. If set, then the publication and
           activation dates must be separated by at least this much time. If the activation date
           is specified but the publication date isn't, then the publication date will default to
           this much time before the activation date; conversely, if the publication date is
           specified but activation date isn't, then activation will be set to this much time
           after publication.

           If the key is being set to be an explicit successor to another key, then the default
           prepublication interval is 30 days; otherwise it is zero.

           As with date offsets, if the argument is followed by one of the suffixes 'y', 'mo',
           'w', 'd', 'h', or 'mi', then the interval is measured in years, months, weeks, days,
           hours, or minutes, respectively. Without a suffix, the interval is measured in
           seconds.

PRINTING OPTIONS

       dnssec-settime can also be used to print the timing metadata associated with a key.

       -u
           Print times in UNIX epoch format.

       -p C/P/A/R/I/D/all
           Print a specific metadata value or set of metadata values. The -p option may be
           followed by one or more of the following letters to indicate which value or values to
           print: C for the creation date, P for the publication date, A for the activation date,
           R for the revocation date, I for the inactivation date, or D for the deletion date. To
           print all of the metadata, use -p all.
