56     <para>
57       <command>nsec3hash</command> generates an NSEC3 hash based on
58       a set of NSEC3 parameters.  This can be used to check the validity
59       of NSEC3 records in a signed zone.

78           <para>
79             A number indicating the hash algorithm.  Currently the
80             only supported hash algorithm for NSEC3 is SHA-1, which is
81             indicated by the number 1; consequently "1" is the only
82             useful value for this argument.
