nsec3hash(1) BIND 9 nsec3hash(1)
NAME
nsec3hash - generate NSEC3 hash
SYNOPSIS
nsec3hash {salt} {algorithm} {iterations} {domain}
nsec3hash -r {algorithm} {flags} {iterations} {salt} {domain}
DESCRIPTION
nsec3hash 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.
If this command is invoked as nsec3hash -r, it takes arguments in 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.
ARGUMENTS
salt This is the salt provided to the hash algorithm.
algorithm
This is 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.
flags This is provided for compatibility with NSEC3 record presentation
format, but is ignored since the flags do not affect the hash.
iterations
This is the number of additional times the hash should be
performed.
domain This is the domain name to be hashed.
