<p><span class="command"><strong>dnssec-checkds</strong></span>
verifies the correctness of Delegation Signer (DS)
resource records for keys in a specified zone.

<div class="variablelist"><dl class="variablelist">
<dt><span class="term">-a <em class="replaceable"><code>algorithm</code></em></span></dt>
<dd>
<p>
Specify a digest algorithm to use when converting the
zone's DNSKEY records to expected DS records. This
option can be repeated, so that multiple records are
checked for each DNSKEY record.
</p>
<p>
The <em class="replaceable"><code>algorithm</code></em> must be one of
SHA-1, SHA-256, or SHA-384. These values are case insensitive,
and the hyphen may be omitted. If no algorithm is specified,
the default is SHA-256.
</p>
</dd>
<dt><span class="term">-f <em class="replaceable"><code>file</code></em></span></dt>
<dd>
<p>
If a <code class="option">file</code> is specified, then the zone is
read from that file to find the DNSKEY records. If not,
then the DNSKEY records for the zone are looked up in the DNS.
</p>
</dd>
<dt><span class="term">-s <em class="replaceable"><code>file</code></em></span></dt>
<dd>
<p>
Specifies a prepared dsset file, such as would be generated
by <span class="command"><strong>dnssec-signzone</strong></span>, to use as a source for
the DS RRset instead of querying the parent.
</p>
</dd>
<dt><span class="term">-d <em class="replaceable"><code>dig path</code></em></span></dt>
<dd>
<p>
Specifies a path to a <span class="command"><strong>dig</strong></span> binary. Used
for testing.

</dd>
<dt><span class="term">-D <em class="replaceable"><code>dsfromkey path</code></em></span></dt>
<dd>
<p>
Specifies a path to a <span class="command"><strong>dnssec-dsfromkey</strong></span> binary.
