.SH SYNOPSIS
.sp
\fBknsec3hash\fP \fIsalt\fP \fIalgorithm\fP \fIiterations\fP \fIname\fP
.SH DESCRIPTION
.sp
This utility generates a NSEC3 hash for a given domain name and parameters of NSEC3 hash.
.SS Parameters
.INDENT 0.0
.TP
\fIsalt\fP
Specifies a binary salt encoded as a hexadecimal string.
.TP
\fIalgorithm\fP
Specifies a hashing algorithm by number. Currently, the only supported algorithm is SHA\-1 (number 1).
.TP
\fIiterations\fP
Specifies the number of additional iterations of the hashing algorithm.
.TP
\fIname\fP
Specifies the domain name to be hashed.
