dnssec-revoke - set the REVOKED bit on a DNSSEC key
---------------------------------------------------

Synopsis
~~~~~~~~

:program:`dnssec-revoke` [**-hr**] [**-v** level] [**-V**] [**-K** directory] [**-E** engine] [**-f**] [**-R**] {keyfile}

Description
~~~~~~~~~~~

:program:`dnssec-revoke` reads a DNSSEC key file, sets the REVOKED bit on the
key as defined in :rfc:`5011`, and creates a new pair of key files
containing the now-revoked key.

Options
~~~~~~~

.. option:: -h

   This option emits a usage message and exits.

.. option:: -K directory

   This option sets the directory in which the key files are to reside.

.. option:: -r

   This option indicates to remove the original keyset files after writing the new keyset files.

.. option:: -v level

   This option sets the debugging level.

.. option:: -V

   This option prints version information.

.. option:: -E engine

   This option specifies the cryptographic hardware to use, when applicable.

   When BIND 9 is built with OpenSSL, this needs to be set to the OpenSSL
   engine identifier that drives the cryptographic accelerator or
   hardware service module (usually ``pkcs11``).

.. option:: -f

   This option indicates a forced overwrite and causes :program:`dnssec-revoke` to write the new key pair,
   even if a file already exists matching the algorithm and key ID of
   the revoked key.

.. option:: -R

   This option prints the key tag of the key with the REVOKE bit set, but does not
   revoke the key.
