424 * is at 56bit (SSL_EXP56). If the exportable cipher class is going to change
425 * again (eg. to 64bit) the use of "SSL_EXP*" becomes blurred even more,
426 * since SSL_EXP64 could be similar to SSL_LOW.
427 * For this reason SSL_MICRO and SSL_MINI macros are included to widen the
428 * namespace of SSL_LOW-SSL_HIGH to lower values. As development of speed
429 * and ciphers goes, another extension to SSL_SUPER and/or SSL_ULTRA would

455 * Even though the macros for EXPORT and EXPORT40/56 have similar names,
456 * their meaning is different:
457 * *_EXPORT macros check the 'exportable' status.
458 * *_EXPORT40/56 macros are used to check whether a certain cipher strength
460 * Since the SSL_IS_EXPORT* and SSL_EXPORT* macros depend on the correct
461 * algorithm structure element to be passed (algorithms, algo_strength) and no
462 * typechecking can be done as they are all of type unsigned long, their
463 * direct usage is discouraged.
