8c2f489baa38f019b839e9e6c460386af42c588dJohn Smith signs a zone. It generates
8c2f489baa38f019b839e9e6c460386af42c588dJohn Smith NSEC and RRSIG records and produces a signed version of the
8c2f489baa38f019b839e9e6c460386af42c588dJohn Smith zone. The security status of delegations from the signed zone
8c2f489baa38f019b839e9e6c460386af42c588dJohn Smith (that is, whether the child zones are secure or not) is
8c2f489baa38f019b839e9e6c460386af42c588dJohn Smith determined by the presence or absence of a
8c2f489baa38f019b839e9e6c460386af42c588dJohn Smith <code class="filename">keyset</code> file for each child zone.

8c2f489baa38f019b839e9e6c460386af42c588dJohn Smith When signing a zone with a fixed signature lifetime, all
8c2f489baa38f019b839e9e6c460386af42c588dJohn Smith RRSIG records issued at the time of signing expires
8c2f489baa38f019b839e9e6c460386af42c588dJohn Smith simultaneously. If the zone is incrementally signed, i.e.
8c2f489baa38f019b839e9e6c460386af42c588dJohn Smith a previously-signed zone is passed as input to the signer,
8c2f489baa38f019b839e9e6c460386af42c588dJohn Smith all expired signatures have to be regenerated at about the
8c2f489baa38f019b839e9e6c460386af42c588dJohn Smith same time. The <code class="option">jitter</code> option specifies a
8c2f489baa38f019b839e9e6c460386af42c588dJohn Smith jitter window that will be used to randomize the signature

8c2f489baa38f019b839e9e6c460386af42c588dJohn Smith from all caches there will be less congestion than if all

<p>
When a key is found, its timing metadata is examined to
determine how it should be used, according to the following
rules. Each successive rule takes priority over the prior
ones:
</p>
<div class="variablelist"><dl class="variablelist">
<dt></dt>
<dd>
<p>
If no timing metadata has been set for the key, the key is
published in the zone and used to sign the zone.
</p>
</dd>
<dt></dt>
<dd>
<p>
If the key's publication date is set and is in the past, the
key is published in the zone.
</p>
</dd>
<dt></dt>
<dd>
<p>
If the key's activation date is set and in the past, the
key is published (regardless of publication date) and
used to sign the zone.
</p>
</dd>
<dt></dt>
<dd>
<p>
If the key's revocation date is set and in the past, and the
key is published, then the key is revoked, and the revoked key
is used to sign the zone.
</p>
</dd>
<dt></dt>
<dd>
<p>
If either of the key's unpublication or deletion dates are set
and in the past, the key is NOT published or used to sign the
zone, regardless of any other metadata.
</p>
</dd>
</dl></div>
</dd>
<dt><span class="term">-T <em class="replaceable"><code>ttl</code></em></span></dt>
<dd>
<p>
Specifies a TTL to be used for new DNSKEY records imported
into the zone from the key repository. If not
specified, the default is the TTL value from the zone's SOA
record. This option is ignored when signing without
<code class="option">-S</code>, since DNSKEY records are not imported
from the key repository in that case. It is also ignored if
there are any pre-existing DNSKEY records at the zone apex,
in which case new records' TTL values will be set to match
them, or if any of the imported DNSKEY records had a default
TTL value. In the event of a a conflict between TTL values in
imported keys, the shortest one is used.
</p>
</dd>
<dt><span class="term">-t</span></dt>
<dd>
<p>
Print statistics at completion.
</p>
</dd>
<dt><span class="term">-u</span></dt>
<dd>
<p>
Update NSEC/NSEC3 chain when re-signing a previously signed
zone. With this option, a zone signed with NSEC can be
switched to NSEC3, or a zone signed with NSEC3 can
be switch to NSEC or to NSEC3 with different parameters.
Without this option, <span class="command"><strong>dnssec-signzone</strong></span> will
retain the existing chain when re-signing.
</p>
</dd>
<dt><span class="term">-v <em class="replaceable"><code>level</code></em></span></dt>
<dd>
<p>
Sets the debugging level.
</p>
</dd>
<dt><span class="term">-x</span></dt>
<dd>
<p>
Only sign the DNSKEY RRset with key-signing keys, and omit
signatures from zone-signing keys. (This is similar to the
<span class="command"><strong>dnssec-dnskey-kskonly yes;</strong></span> zone option in
<span class="command"><strong>named</strong></span>.)
</p>
</dd>
<dt><span class="term">-z</span></dt>
<dd>
<p>
Ignore KSK flag on key when determining what to sign. This
causes KSK-flagged keys to sign all records, not just the
DNSKEY RRset. (This is similar to the
<span class="command"><strong>update-check-ksk no;</strong></span> zone option in
<span class="command"><strong>named</strong></span>.)
</p>
</dd>
<dt><span class="term">-3 <em class="replaceable"><code>salt</code></em></span></dt>
<dd>
<p>
Generate an NSEC3 chain with the given hex encoded salt.
A dash (<em class="replaceable"><code>salt</code></em>) can
be used to indicate that no salt is to be used when generating the NSEC3 chain.
</p>
</dd>
<dt><span class="term">-H <em class="replaceable"><code>iterations</code></em></span></dt>
<dd>
<p>
When generating an NSEC3 chain, use this many iterations. The
default is 10.
</p>
</dd>
<dt><span class="term">-A</span></dt>
<dd>
<p>
When generating an NSEC3 chain set the OPTOUT flag on all
NSEC3 records and do not generate NSEC3 records for insecure
delegations.
</p>
<p>
Using this option twice (i.e., <code class="option">-AA</code>)
turns the OPTOUT flag off for all records. This is useful
when using the <code class="option">-u</code> option to modify an NSEC3
chain which previously had OPTOUT set.
</p>
</dd>
<dt><span class="term">zonefile</span></dt>
<dd>
<p>
The file containing the zone to be signed.
</p>
</dd>
<dt><span class="term">key</span></dt>
<dd>
<p>
Specify which keys should be used to sign the zone. If
no keys are specified, then the zone will be examined
for DNSKEY records at the zone apex. If these are found and
there are matching private keys, in the current directory,
then these will be used for signing.

<a name="id-1.9"></a><h2>EXAMPLE</h2>
<p>
The following command signs the <strong class="userinput"><code>example.com</code></strong>
zone with the DSA key generated by <span class="command"><strong>dnssec-keygen</strong></span>
(Kexample.com.+003+17247). Because the <span class="command"><strong>-S</strong></span> option
is not being used, the zone's keys must be in the master file
(<code class="filename">db.example.com</code>). This invocation looks
for <code class="filename">dsset</code> files, in the current directory,
so that DS records can be imported from them (<span class="command"><strong>-g</strong></span>).
</p>
<pre class="programlisting">% dnssec-signzone -g -o example.com db.example.com \
Kexample.com.+003+17247
db.example.com.signed
%</pre>
<p>
In the above example, <span class="command"><strong>dnssec-signzone</strong></span> creates
the file <code class="filename">db.example.com.signed</code>. This
file should be referenced in a zone statement in a
<code class="filename">named.conf</code> file.
</p>
<p>
This example re-signs a previously signed zone with default parameters.
The private keys are assumed to be in the current directory.
</p>
<pre class="programlisting">% cp db.example.com.signed db.example.com
% dnssec-signzone -o example.com db.example.com
db.example.com.signed
