/*\brief Put here specific PKCS#11 tweaks
 *
 *\li PK11_<mechanism>_SKIP:
 *	Don't consider the lack of this mechanism as a fatal error.
 *
 *\li PK11_<mechanism>_REPLACE:
 *      Same as SKIP, and implement the mechanism using lower-level steps.
 *
 *\li PK11_<algorithm>_DISABLE:
 *	Same as SKIP, and disable support for the algorithm.
 *
 *\li PK11_PAD_HMAC_KEYS:
 *	Extend HMAC keys shorter than digest length.
 */
