KNSEC3HASH(1)

NAME
knsec3hash - Simple utility to compute NSEC3 hash

SYNOPSIS

knsec3hash salt algorithm iterations name

knsec3hash algorithm flags iterations salt name

knsec3hash [-h] [-V]

DESCRIPTION

This utility generates an 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.

  Options

-h, --help
    Print the program help.

-V, --version
    Print the program version. The option -VV makes the program print the compile time configuration summary.

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)
