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 relative 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.
