knsec3hash – NSEC hash computation utility
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
