KNSEC3HASH(1) Knot DNS KNSEC3HASH(1)

knsec3hash - Simple utility to compute NSEC3 hash

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.

Specifies a binary salt encoded as a hexadecimal string.
Specifies a hashing algorithm by number. Currently, the only supported algorithm is SHA-1 (number 1).
Specifies the number of additional iterations of the hashing algorithm.
Specifies the domain name to be hashed.
Specifies NSEC3 flags as an unsigned integer.

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