 *    2) The mechanism flags are restricted to only those that map to
 *       fips approved operations.
 *    3) All key sizes are in bits, independent of mechanism.
 *    4) You can add more then one entry for the same mechanism to handle
 *       multiple descrete keys where the MIN/MAX/STEP semantics doesn't apply
 *       or where different operations have different key requirements.
 * This table does not encode all the modules legal FIPS semantics, only
