SYNOPSIS
genkrf [options] <zone-file> [<signed-zone-file>]
DESCRIPTION
genkrf generates a keyrec file from KSK and/or ZSK files. It generates new KSK and ZSK keys if needed.The name of the keyrec file to be generated is given by the -krfile option. If this option is not specified, zone-name.krf is used as the name of the keyrec file. If the keyrec file already exists, it will be overwritten with new keyrec definitions.
The zone-file argument is required. It specifies the name of the zone file from which the signed zone file was created. The optional signed-zone-file argument specifies the name of the signed zone file. If it is not given, then it defaults to zone-file.signed. The signed zone file field is, in effect, a dummy field as the zone file is not actually signed.
OPTIONS
genkrf has a number of options that assist in creation of the keyrec file. These options will be set to the first value found from this search path:
command line options
DNSSEC-Tools configuration file
DNSSEC-Tools defaults
See tooloptions.pm(3) for more details. Exceptions to this are given in the option descriptions.
The genkrf options are described below.
General genkrf Options
- -zone zone-name
- This option specifies the name of the zone. If it is not given then zone-file will be used as the name of the zone.
- -krfile keyrec-file
- This option specifies the name of the keyrec file to be generated. If it is not given, then zone-name.krf will be used.
- -algorithm algorithm
- This option specifies the algorithm used to generate encryption keys.
- -endtime endtime
- This option specifies the time that the signature on the zone expires, measured in seconds.
- -random random-device
- Source of randomness used to generate the zone's keys. See the man page for dnssec-signzone for the valid format of this field.
- -verbose
- Display additional messages during processing. If this option is given at least once, then a message will be displayed indicating the successful generation of the keyrec file. If it is given twice, then the values of all options will also be displayed.
- -Version
- Displays the version information for genkrf and the DNSSEC-Tools package.
- -help
- Display a usage message.
KSK-related Options
- -kskcur KSK-name
- This option specifies the Current KSK's key file being used to sign the zone. If this option is not given, a new KSK will be created.
- -kskcount KSK-count
- This option specifies the number of KSK keys that will be generated. If this option is not given, the default given in the DNSSEC-Tools configuration file will be used.
- -kskdir KSK-directory
- This option specifies the absolute or relative path of the directory where the KSK resides. If this option is not given, it defaults to the current directory ``.''.
- -ksklength KSK-length
- This option specifies the length of the KSK encryption key.
- -ksklife KSK-lifespan
- This option specifies the lifespan of the KSK encryption key. This lifespan is not inherent to the key itself. It is only used to determine when the KSK must be rolled over.
ZSK-related Options
- -zskcur ZSK-name
- This option specifies the current ZSK being used to sign the zone. If this option is not given, a new ZSK will be created.
- -zskpub ZSK-name
- This option specifies the published ZSK for the zone. If this option is not given, a new ZSK will be created.
- -zskcount ZSK-count
- This option specifies the number of current and published ZSK keys that will be generated. If this option is not given, the default given in the DNSSEC-Tools configuration file will be used.
- -zskdir ZSK-directory
- This option specifies the absolute or relative path of the directory where the ZSKs reside. If this option is not given, it defaults to the current directory ``.''.
- -zsklength ZSK-length
- This option specifies the length of the ZSK encryption key.
- -zsklife ZSK-lifespan
- This option specifies the lifespan of the ZSK encryption key. This lifespan is not inherent to the key itself. It is only used to determine when the ZSK must be rolled over.
