.SH NAME
knsec3hash \- Simple utility to compute NSEC3 hash
.SH SYNOPSIS
.sp
\fBknsec3hash\fP \fIsalt\fP \fIalgorithm\fP \fIiterations\fP \fIname\fP
.sp
\fBknsec3hash\fP \fIalgorithm\fP \fIflags\fP \fIiterations\fP \fIsalt\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.
.TP
\fIflags\fP
Specifies NSEC3 flags as an unsigned integer.
.UNINDENT
.SH EXIT VALUES
.sp
Exit status of 0 means successful operation. Any other exit status indicates
an error.
