       dnssec-signzone signs a zone. It generates NSEC and RRSIG  records  and
       produces  a  signed version of the zone. The security status of delega-
       tions from the signed zone (that is, whether the child zones are secure
       or  not)  is determined by the presence or absence of a keyset file for
       each child zone.

       -a     Verify all generated signatures.

       -c class
              Specifies the DNS class of the zone.

       -k key Treat specified key as a key signing key ignoring any key flags.
              This option may be specified multiple times.

       -l domain
              Generate  a DLV set in addition to the key (DNSKEY) and DS sets.
              The domain is appended to the name of the records.

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

       -g     Generate DS records for child zones from keyset files.  Existing
              DS records will be removed.

       -s start-time
              Specify  the  date  and  time  when  the generated RRSIG records
              become valid. This can be either an absolute or  relative  time.
              An  absolute  start time is indicated by a number in YYYYMMDDHH-
              MMSS notation; 20000530144500 denotes 14:45:00 UTC on May  30th,
              2000.  A relative start time is indicated by +N, which is N sec-
              onds from the current time.  If no start-time is specified,  the
              current time minus 1 hour (to allow for clock skew) is used.

       -e end-time
              Specify  the  date  and  time  when  the generated RRSIG 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

       -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-

       -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 RRSIG 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 sig-
              natures that are valid for 30 days, with a cycle interval of 7.5
              days. Therefore, if any existing RRSIG 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

       -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 indi-
              cates that keyboard input should be used.

       -t     Print statistics at completion.

       -v level
              Sets the debugging level.

       -z     Ignore KSK flag on key when determining what to sign.

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

       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

       The  following command signs the example.com zone with the DSA key gen-
       erated in the dnssec-keygen man page. The zone's keys must  be  in  the
       zone.  If there are keyset files associated with 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.exam-
       ple.com.signed. This file should be referenced in a zone statement in a
       named.conf file.
