keymod

KEYMOD(1p)						User Contributed Perl Documentation						KEYMOD(1p)

NAME

       keymod - Modifies key parameters in a DNSSEC-Tools keyrec file

SYNOPSIS

	 keymod [options] keyrec1 ... keyrecN

DESCRIPTION

       keymod modifies the key parameters in a keyrec file that are used to generate cryptographics keys used to sign zones.  The new parameters
       will be used by zonesigner when generating new keys.  It has no effect on existing keys.

       zonesigner will use the new parameter for a zone the next time it generates a key that requires that parameter.	This means that, for
       example, a new ZSK length will not be used during the next invocation of zonesigner if that invocation will be performing KSK-rollover
       actions.

       The following fields may be modified:

	   kskcount - count of KSK keys
	   ksklength - length of KSK keys
	   ksklife - lifetime of KSK keys
	   random - random number generator device file
	   revperiod - revocation period for KSK keys
	   zskcount - count of ZSK keys
	   zsklength - length of ZSK keys
	   zsklife - lifetime of ZSK keys

       New key/value fields will be added to a zone keyrec file to inform zonesigner that new values should be used.  The key portion of the added
       fields will begin with "new_".  For example, a new KSK length of 2048 will be written to the keyrec file as:

	   new_ksklength	2048

       All zone records in the specified keyrec file will be modified, unless the -zone option is given.  In that case, only the named zone will
       be modified.

       If a zone keyrec already contains a new key/value field, then the value will be modified on subsequent runs of keymod.

OPTIONS

       keymod recognizes the following options.  Multiple options may be combined in a single keymod execution.

       All numeric values must be positive or zero.

       If a new key/value field should be deleted from a zone keyrec, then a zero or empty string value should be specified for the appropriate
       option.

       -zone zonename
	   The zone keyrec whose name matches zonename is selected as the only keyrec that will be modified.  If this name is not given, then all
	   zone keyrec records will be modified.

       -ksklength ksklength
	   The ksklength field will be modified in the selected keyrec records to the given value.  This is a numeric field whose values depend on
	   the cryptographic algorithm to be used to generate keys for the zone.

       -kskcount kskcount
	   The kskcount field will be modified in the selected keyrec records to the given value.  This is a numeric field.

       -ksklife ksklife
	   The ksklife field will be modified in the selected keyrec records to the given value.  This is a numeric field.

       -random random
	   The random field will be modified in the selected keyrec records to the given value.  This is a text field that will be passed to the
	   key generator.

       -revperiod revperiod
	   The revperiod field will be modified in the selected keyrec records to the given value.  This is a numeric field.

       -zskcount zskcount
	   The zskcount field will be modified in the selected keyrec records to the given value.  This is a numeric field.

       -zsklength zsklength
	   The zsklength field will be modified in the selected keyrec records to the given value.  This is a numeric field whose values depend on
	   the cryptographic algorithm to be used to generate keys for the zone.

       -zsklife zsklife
	   The zsklife field will be modified in the selected keyrec records to the given value.  This is a numeric field.

       -nocheck
	   If this option is given, the krfcheck command will not be run on the modified keyrec file.

       -verbose
	   Display information about every modification made to the keyrec file.

       -Version
	   Displays the version information for keymod and the DNSSEC-Tools package.

       -help
	   Display a usage message.
