Synopsis
|
|
~~~~~~~~
|
|
|
|
:program:`nsec3hash` {salt} {algorithm} {iterations} {domain}
|
|
|
|
:program:`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.
