    <title>DESCRIPTION</title>
    <para>
        <command>dnssec-signzone</command> signs a zone.  It generates NXT
	and SIG records and produces a signed version of the zone.  If there
	is a <filename>signedkey</filename> 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
        signed zone (that is, whether the child zones are secure or not) is
        determined by the presence or absence of a
	<filename>signedkey</filename> file for each child zone.
    </para>

      <varlistentry>
        <term>-c <replaceable class="parameter">class</replaceable></term>
	<listitem>
	  <para>
	       Specifies the DNS class of the zone.
	  </para>
	</listitem>
      </varlistentry>

      <varlistentry>
        <term>-d <replaceable class="parameter">directory</replaceable></term>
	<listitem>
	  <para>
	       Look for <filename>signedkey</filename> files in
	       <option>directory</option> as the directory 
	  </para>
	</listitem>
      </varlistentry>

      <varlistentry>
        <term>-s <replaceable class="parameter">start-time</replaceable></term>
	<listitem>
	  <para>
	       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 <option>start-time</option> is specified, the current
	       time is used.
	  </para>
	</listitem>
      </varlistentry>

      <varlistentry>
        <term>-e <replaceable class="parameter">end-time</replaceable></term>
	<listitem>
	  <para>
	       Specify the date and time when the generated SIG records
	       expire.  As with <option>start-time</option>, 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 <option>end-time</option> is
	       specified, 30 days from the start time is used as a default.
	  </para>
	</listitem>
      </varlistentry>

      <varlistentry>
        <term>-f <replaceable class="parameter">output-file</replaceable></term>
	<listitem>
	  <para>
	       The name of the output file containing the signed zone.  The
	       default is to append <filename>.signed</filename> to the
	       input file.
	  </para>
	</listitem>
      </varlistentry>

      <varlistentry>
        <term>-h</term>
	<listitem>
	  <para>
	       Prints a short summary of the options and arguments to
	       <command>dnssec-signzone</command>.
	  </para>
	</listitem>
      </varlistentry>

      <varlistentry>
        <term>-i <replaceable class="parameter">interval</replaceable></term>
	<listitem>
	  <para>
	       When a previously signed zone is passed as input, records
	       may be resigned.  The <option>interval</option> 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.
	  </para>
	  <para>
	       The default cycle interval is one quarter of the difference
	       between the signature end and start times.  So if neither
	       <option>end-time</option> or <option>start-time</option>
	       are specified, <command>dnssec-signzone</command> 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.
	  </para>
	</listitem>
      </varlistentry>

      <varlistentry>
        <term>-n <replaceable class="parameter">ncpus</replaceable></term>
	<listitem>
	  <para>
	       Specifies the number of threads to use.  By default, one
	       thread is started for each detected CPU.
	  </para>
	</listitem>
      </varlistentry>

      <varlistentry>
        <term>-o <replaceable class="parameter">origin</replaceable></term>
	<listitem>
	  <para>
	       The zone origin.  If not specified, the name of the zone file
	       is assumed to be the origin.
	  </para>
	</listitem>
      </varlistentry>

      <varlistentry>
        <term>-p</term>
	<listitem>
	  <para>
	       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.
	  </para>
	</listitem>
      </varlistentry>

      <varlistentry>
        <term>-r <replaceable class="parameter">randomdev</replaceable></term>
	<listitem>
	  <para>
	       Specifies the source of randomness.  If the operating
	       system does not provide a <filename>/dev/random</filename>
	       or equivalent device, the default source of randomness
	       is keyboard input.  <filename>randomdev</filename> specifies
	       the name of a character device or file containing random
	       data to be used instead of the default.  The special value
	       <filename>keyboard</filename> indicates that keyboard
	       input should be used.
	  </para>

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

      <varlistentry>
        <term>key</term>
	<listitem>
	  <para>
	       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.

    <title>EXAMPLE</title>
    <para>
        The following command signs the <userinput>example.com</userinput>
	zone with the DSA key generated in the <command>dnssec-keygen</command>
	man page.  The zone's keys must be in the zone.  If there are
	<filename>signedkey</filename> files associated with this zone
	or any child zones, they must be in the current directory.
	<userinput>example.com</userinput>, the following command would be
	issued:
    </para>
    <para>
        <userinput>dnssec-signzone -o example.com db.example.com Kexample.com.+003+26160</userinput>
    </para>
    <para>
        The command would print a string of the form:
    </para>
    <para>
        In this example, <command>dnssec-signzone</command> creates
	the file <filename>db.example.com.signed</filename>.  This file
	should be referenced in a zone statement in a
	<filename>named.conf</filename> file.
