|
||
|
||
<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.
|
||
</p>
|
||
|
||
<p>
|
||
If this command is invoked as <span class="command"><strong>nsec3hash -r</strong></span>,
|
||
it takes arguments in an order matching the first four fields
|
||
of an NSEC3 record, followed by the domain name: algorithm, flags,
|
||
iterations, salt, domain. This makes it convenient to copy and
|
||
paste a portion of an NSEC3 or NSEC3PARAM record into a command
|
||
line to confirm the correctness of an NSEC3 hash.

||

<div class="variablelist"><dl class="variablelist">

<dt><span class="term">salt</span></dt>
|

The salt provided to the hash algorithm.

<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.

<dd>

<p>

Provided for compatibility with NSEC3 record presentation
|
||
format, but ignored since the flags do not affect the hash.
