35 <span class="command"><strong>nsec3hash</strong></span> generates an NSEC3 hash based on
36 a set of NSEC3 parameters. This can be used to check the validity
37 of NSEC3 records in a signed zone.
40 <div class="refsection">
41 <a name="id-1.8"></a><h2>ARGUMENTS</h2>
42 <div class="variablelist"><dl class="variablelist">
43 <dt><span class="term">salt</span></dt>
45 The salt provided to the hash algorithm.
47 <dt><span class="term">algorithm</span></dt>
49 A number indicating the hash algorithm. Currently the
50 only supported hash algorithm for NSEC3 is SHA-1, which is
51 indicated by the number 1; consequently "1" is the only
52 useful value for this argument.
54 <dt><span class="term">iterations</span></dt>
56 The number of additional times the hash should be performed.
58 <dt><span class="term">domain</span></dt>
60 The domain name to be hashed.
