knsec3hash – NSEC hash computation utility

Synopsis

knsec3hash salt algorithm iterations name

Description

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

Parameters

salt

Specifies binary salt encoded as a hexadecimal string.

algorithm

Specifies hashing algorithm 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.

Examples

$ knsec3hash c01dcafe 1 10 knot-dns.cz
7PTVGE7QV67EM61ROS9238P5RAKR2DM7 (salt=c01dcafe, hash=1, iterations=10)

$ knsec3hash - 1 0 net
