+
+nsec3hash - generate NSEC3 hash
+-------------------------------
+
+Synopsis
+~~~~~~~~
+
+:program:`nsec3hash` {salt} {algorithm} {iterations} {domain}
+
+:program:`nsec3hash` **-r** {algorithm} {flags} {iterations} {salt} {domain}
+
+Description
+~~~~~~~~~~~
+
+:program:`nsec3hash` 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.
+
+If this command is invoked as ``nsec3hash -r``, it takes arguments in
+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.
+
+Arguments
+~~~~~~~~~
+
+.. option:: salt
+
+   This is the salt provided to the hash algorithm.
+
+.. option:: algorithm
+
+   This is 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.
+
+.. option:: flags
+
+   This is provided for compatibility with NSEC3 record presentation format, but
+   is ignored since the flags do not affect the hash.
+
+.. option:: iterations
+
+   This is the number of additional times the hash should be performed.
+
+.. option:: domain
+
+   This is the domain name to be hashed.
