`knsec3hash` – NSEC hash computation utility¶

Synopsis¶

knsec3hash salt algorithm iterations name

knsec3hash algorithm flags iterations salt name

This utility generates a NSEC3 hash for a given domain name and parameters of NSEC3 hash.

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