DESCRIPTION

       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.

OPTIONS

       -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
	      default.

       -f output-file
	      The  name  of  the  output  file containing the signed zone. The
	      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
	      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 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.

       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 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:
