NAME

6       knsec3hash - Simple utility to compute NSEC3 hash
7

SYNOPSIS

9       knsec3hash salt algorithm iterations name
10

DESCRIPTION

12       This utility generates a NSEC3 hash for a given domain name and parame‐
13       ters of NSEC3 hash.
14
15   Parameters
16       salt   Specifies a binary salt encoded as a hexadecimal string.
17
18       algorithm
19              Specifies a hashing algorithm by  number.  Currently,  the  only
20              supported algorithm is SHA-1 (number 1).
21
22       iterations
23              Specifies  the  number  of  additional iterations of the hashing
24              algorithm.
25
26       name   Specifies the domain name to be hashed.
27

EXIT VALUES

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