416 * Export and cipher strength information. For each cipher we have to decide

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

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