KNSEC3HASH(1)

NAME
knsec3hash - 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.

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)
