<p>
<span class="command"><strong>nsec3hash</strong></span> generates an NSEC3 hash based on
a set of NSEC3 parameters. This can be used to check the validity
of NSEC3 records in a signed zone.

<a name="id-1.8"></a><h2>ARGUMENTS</h2>
<div class="variablelist"><dl class="variablelist">
<dt><span class="term">salt</span></dt>
<dd>
<p>
The salt provided to the hash algorithm.
</p>
</dd>
<dt><span class="term">algorithm</span></dt>
<dd>
<p>
A number indicating the hash algorithm. Currently the
only supported hash algorithm for NSEC3 is SHA-1, which is
indicated by the number 1; consequently "1" is the only
useful value for this argument.
</p>
</dd>
<dt><span class="term">iterations</span></dt>
<dd>
<p>
The number of additional times the hash should be performed.
</p>
</dd>
<dt><span class="term">domain</span></dt>
<dd>
<p>
The domain name to be hashed.
