970N/A<p><span><strong class="command">dnssec-signzone</strong></span>
970N/A signs a zone. It generates
970N/A NSEC and RRSIG records and produces a signed version of the
970N/A zone. The security status of delegations from the signed zone
970N/A (that is, whether the child zones are secure or not) is
970N/A determined by the presence or absence of a
970N/A <code class="filename">keyset</code> file for each child zone.
970N/A </p>

1366N/A<dd><p>
1366N/A Generate DS records for child zones from keyset files.
1549N/A Existing DS records will be removed.

1634N/A<dt><span class="term">-s <em class="replaceable"><code>start-time</code></em></span></dt>
1634N/A<dd><p>
970N/A Specify the date and time when the generated RRSIG records
98N/A become valid. This can be either an absolute or relative
98N/A time. An absolute start time is indicated by a number
1265N/A in YYYYMMDDHHMMSS notation; 20000530144500 denotes
1451N/A 14:45:00 UTC on May 30th, 2000. A relative start time is
1451N/A indicated by +N, which is N seconds from the current time.
1451N/A If no <code class="option">start-time</code> is specified, the current
1451N/A time minus 1 hour (to allow for clock skew) is used.
1124N/A </p></dd>
1451N/A<dt><span class="term">-e <em class="replaceable"><code>end-time</code></em></span></dt>
1451N/A<dd><p>
1124N/A Specify the date and time when the generated RRSIG records
1124N/A expire. As with <code class="option">start-time</code>, an absolute
1265N/A time is indicated in YYYYMMDDHHMMSS notation. A time relative
1265N/A to the start time is indicated with +N, which is N seconds from
1265N/A the start time. A time relative to the current time is
1124N/A indicated with now+N. If no <code class="option">end-time</code> is
98N/A specified, 30 days from the start time is used as a default.
493N/A </p></dd>
98N/A<dt><span class="term">-f <em class="replaceable"><code>output-file</code></em></span></dt>
970N/A<dd><p>
970N/A The name of the output file containing the signed zone. The
970N/A default is to append <code class="filename">.signed</code> to
1026N/A the
970N/A input filename.
970N/A </p></dd>
1026N/A<dt><span class="term">-h</span></dt>
1124N/A<dd><p>
1523N/A Prints a short summary of the options and arguments to
1523N/A <span><strong class="command">dnssec-signzone</strong></span>.
1451N/A </p></dd>
1451N/A<dt><span class="term">-i <em class="replaceable"><code>interval</code></em></span></dt>
1451N/A<dd>
1003N/A<p>
98N/A When a previously-signed zone is passed as input, records
1466N/A may be resigned. The <code class="option">interval</code> option
98N/A specifies the cycle interval as an offset from the current
908N/A time (in seconds). If a RRSIG record expires after the
591N/A cycle interval, it is retained. Otherwise, it is considered
493N/A to be expiring soon, and it will be replaced.
493N/A </p>
493N/A<p>
493N/A The default cycle interval is one quarter of the difference
493N/A between the signature end and start times. So if neither
493N/A <code class="option">end-time</code> or <code class="option">start-time</code>
493N/A are specified, <span><strong class="command">dnssec-signzone</strong></span>
493N/A generates
1026N/A signatures that are valid for 30 days, with a cycle
705N/A interval of 7.5 days. Therefore, if any existing RRSIG records
493N/A are due to expire in less than 7.5 days, they would be
1634N/A replaced.
557N/A </p>
1176N/A</dd>
493N/A<dt><span class="term">-I <em class="replaceable"><code>input-format</code></em></span></dt>
965N/A<dd><p>
965N/A The format of the input zone file.
965N/A Possible formats are <span><strong class="command">"text"</strong></span> (default)
1196N/A and <span><strong class="command">"raw"</strong></span>.
1196N/A This option is primarily intended to be used for dynamic
1477N/A signed zones so that the dumped zone file in a non-text
1196N/A format containing updates can be signed directly.
1196N/A The use of this option does not make much sense for
1425N/A non-dynamic zones.
1196N/A </p></dd>
1428N/A<dt><span class="term">-j <em class="replaceable"><code>jitter</code></em></span></dt>
1428N/A<dd>
1428N/A<p>
1196N/A When signing a zone with a fixed signature lifetime, all
1425N/A RRSIG records issued at the time of signing expires
1425N/A simultaneously. If the zone is incrementally signed, i.e.
1425N/A a previously-signed zone is passed as input to the signer,
1425N/A all expired signatures have to be regenerated at about the
1196N/A same time. The <code class="option">jitter</code> option specifies a
606N/A jitter window that will be used to randomize the signature
606N/A expire time, thus spreading incremental signature
851N/A regeneration over time.
851N/A </p>
851N/A<p>
851N/A Signature lifetime jitter also to some extent benefits
851N/A validators and servers by spreading out cache expiration,
851N/A i.e. if large numbers of RRSIGs don't expire at the same time
851N/A from all caches there will be less congestion than if all
98N/A validators need to refetch at mostly the same time.

970N/A for <code class="filename">keyset</code> files, in the current directory,
970N/A so that DS records can be generated from them (<span><strong class="command">-g</strong></span>).
