dnssec-settime

## Name

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

## Synopsis

`dnssec-settime` [`-fr`] [`-K `directory``] [`-P `date/offset``] [`-A `date/offset``] [`-R `date/offset``] [`-U `date/offset``] [`-D `date/offset``] [`-h`] [`-v `level``] {keyfile}

## DESCRIPTION

dnssec-settime reads a DNSSEC private key file and sets the key timing metadata as specified by the `-P`, `-A`, `-R`, `-U`, 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.

## 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.

-K `directory`

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

-h

  Emit usage message and exit.

-v `level`

  Sets the debugging level.

## 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'.

-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 and 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.

-U `date/offset`

  Sets the date on which the key is to be unpublished. After that date, the key will no longer be included in the zone, but it may remain in the key repository.

-D `date/offset`

  Sets the date on which the key is to be deleted. After that date, the key can be removed from the key repository. NOTE: Keys are not currently deleted automatically; this field is included for informational purposes and for future development.

## 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/U/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 revokation date, `U` for the unpublication date, or `D` for the deletion date. To print all of the metadata, use `-p all`.
