SYNOPSIS
       dnssec-signzone [ -a ]  [ -c class ]  [ -d directory ]  [ -s start-time
       ]  [ -e end-time ]  [ -f output-file ]  [ -h ]  [ -i interval ]  [ -n

DESCRIPTION
       dnssec-signzone signs a zone. It generates NXT and SIG records and
       produces a signed version of the zone. If there is a signedkey file
       from the zone's parent, the parent's signatures will be incorporated
       into the generated signed zone file. The security status of delegations
       from the the signed zone (that is, whether the child zones are secure
       or not) is determined by the presence or absence of a signedkey file
       for each child zone.

OPTIONS
       -a     Verify all generated signatures.

       -c class
              Specifies the DNS class of the zone.

       -d directory
              Look for signedkey files in directory as the directory

       -s start-time
              Specify the date and time when the generated SIG records become
              valid. This can be either an absolute or relative time. An
              absolute start time is indicated by a number in YYYYMMDDHHMMSS
              notation; 20000530144500 denotes 14:45:00 UTC on May 30th, 2000.
              A relative start time is indicated by +N, which is N seconds
              from the current time.  If no start-time is specified, the
              current time is used.

       -e end-time
              Specify the date and time when the generated SIG records expire.
              As with start-time, an absolute time is indicated in
              YYYYMMDDHHMMSS notation. A time relative to the start time is
              indicated with +N, which is N seconds from the start time. A
              time realtive to the current time is indicated with now+N. If no
              end-time is specified, 30 days from the start time is used as a
              default.

       -f output-file
              The name of the output file containing the signed zone. The
              default is to append .signed to the input file.

       -h     Prints a short summary of the options and arguments to dnssec-
              signzone.

       -i interval
              When a previously signed zone is passed as input, records may be
              resigned. The interval option specifies the cycle interval as an
              offset from the current time (in seconds). If a SIG record
              expires after the cycle interval, it is retained. Otherwise, it
              is considered to be expiring soon, and it will be replaced.

              The default cycle interval is one quarter of the difference
              between the signature end and start times. So if neither end-
              time or start-time are specified, dnssec-signzone generates
              signatures that are valid for 30 days, with a cycle interval of
              7.5 days. Therefore, if any existing SIG records are due to
              expire in less than 7.5 days, they would be replaced.

       -n ncpus
              Specifies the number of threads to use. By default, one thread
              is started for each detected CPU.

       -o origin
              The zone origin. If not specified, the name of the zone file is
              assumed to be the origin.

       -p     Use pseudo-random data when signing the zone. This is faster,
              but less secure, than using real random data. This option may be
              useful when signing large zones or when the entropy source is
              limited.

       -r randomdev
              Specifies the source of randomness. If the operating system does
              not provide a /dev/random or equivalent device, the default
              source of randomness is keyboard input. randomdev specifies the
              name of a character device or file containing random data to be
              used instead of the default. The special value keyboard
              indicates that keyboard input should be used.

       -t     Print statistics at completion.

       -v level
              Sets the debugging level.

       zonefile
              The file containing the zone to be signed.  Sets the debugging
              level.

       key    The keys used to sign the zone. If no keys are specified, the
              default all zone keys that have private key files in the current
              directory.

EXAMPLE
       The following command signs the example.com zone with the DSA key
       generated in the dnssec-keygen man page. The zone's keys must be in the
       zone. If there are signedkey files associated with this zone or any
       child zones, they must be in the current directory.  example.com, the
       following command would be issued:

       dnssec-signzone -o example.com db.example.com Kexample.com.+003+26160

       The command would print a string of the form:

       In this example, dnssec-signzone creates the file
       db.example.com.signed. This file should be referenced in a zone
       statement in a named.conf file.
