       This utility generates a NSEC3 hash for a given domain name and parameters of NSEC3 hash.

   Parameterssalt   Specifies a binary salt encoded as a hexadecimal string.

       algorithm
              Specifies  a hashing algorithm by number. Currently, the only supported algorithm is SHA-1 (number
              1).

       iterations
              Specifies the number of additional iterations of the hashing algorithm.

       name   Specifies the domain name to be hashed.

       flags  Specifies NSEC3 flags as an unsigned integer.

   Options-h, --help
              Print the program help.

       -V, --version
              Print the program version. The option -VV makes the program print the compile  time  configuration
              summary.

          A1RT98BS5QGC9NFI51S9HCI47ULJG6JH (salt=-, hash=1, iterations=0)

       Exit status of 0 means successful operation. Any other exit status indicates an error.
