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.

Exit values

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

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)
