knsec3hash – NSEC hash computation utility

Synopsis

knsec3hash salt algorithm iterations name

Description

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

Parameters

salt

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.

Examples

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

$ knsec3hash - 1 0 net
A1RT98BS5QGC9NFI51S9HCI47ULJG6JH (salt=-, hash=1, iterations=0)
