.SH SYNOPSIS
|
|
.sp
|
|
\fBnsec3hash\fP {salt} {algorithm} {iterations} {domain}
|
|
.sp
|
|
\fBnsec3hash\fP \fB\-r\fP {algorithm} {flags} {iterations} {salt} {domain}
|
|
.SH DESCRIPTION
|
|
.sp
|
|
\fBnsec3hash\fP generates an NSEC3 hash based on a set of NSEC3
|
|
parameters. This can be used to check the validity of NSEC3 records in a
|
|
signed zone.
|
|
.sp
|
|
If this command is invoked as \fBnsec3hash \-r\fP, it takes arguments in an
|
|
order matching the first four fields of an NSEC3 record, followed by the
|
|
domain name: algorithm, flags, iterations, salt, domain. This makes it
|
|
convenient to copy and paste a portion of an NSEC3 or NSEC3PARAM record
|
|
into a command line to confirm the correctness of an NSEC3 hash.
|
|
.SH ARGUMENTS
|
|
.INDENT 0.0
|
|
.TP
|
|
.B \fBsalt\fP
|
|
The salt provided to the hash algorithm.
|
|
.TP
|
|
.B \fBalgorithm\fP
|
|
A number indicating the hash algorithm. Currently the only supported
|
|
hash algorithm for NSEC3 is SHA\-1, which is indicated by the number
|
|
1; consequently "1" is the only useful value for this argument.
|
|
.TP
|
|
.B \fBflags\fP
|
|
Provided for compatibility with NSEC3 record presentation format, but
|
|
ignored since the flags do not affect the hash.
|
|
.TP
|
|
.B \fBiterations\fP
|
|
The number of additional times the hash should be performed.
|
|
.TP
|
|
.B \fBdomain\fP
|
|
The domain name to be hashed.
