NAME

6       knsec3hash - Simple utility to compute NSEC3 hash
7

SYNOPSIS

9       knsec3hash salt algorithm iterations name
10
11       knsec3hash algorithm flags iterations salt name
12

DESCRIPTION

14       This utility generates a NSEC3 hash for a given domain name and parame‐
15       ters of NSEC3 hash.
16
17   Parameters
18       salt   Specifies a binary salt encoded as a hexadecimal string.
19
20       algorithm
21              Specifies a hashing algorithm by  number.  Currently,  the  only
22              supported algorithm is SHA-1 (number 1).
23
24       iterations
25              Specifies the number of additional iterations of the hashing al‐
26              gorithm.
27
28       name   Specifies the domain name to be hashed.
29

EXIT VALUES

31       Exit status of 0 means successful operation. Any other exit status  in‐
32       dicates an error.
