Simple utility to compute NSEC3 hash

Synopsis

knsec3hash salt algorithm iterations name

knsec3hash algorithm flags iterations salt 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.

flags

Specifies NSEC3 flags as an unsigned integer.

Exit Values

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

Examples

$ knsec3hash 1 0 10 c01dcafe knot-dns.cz
7PTVGE7QV67EM61ROS9238P5RAKR2DM7 (salt=c01dcafe, hash=1, iterations=10)
$ knsec3hash - 1 0 net
A1RT98BS5QGC9NFI51S9HCI47ULJG6JH (salt=-, hash=1, iterations=0)
