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.
