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

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

446 * their meaning is different:
447 * *_EXPORT macros check the 'exportable' status.
448 * *_EXPORT40/56 macros are used to check whether a certain cipher strength
450 * Since the SSL_IS_EXPORT* and SSL_EXPORT* macros depend on the correct
451 * algorithm structure element to be passed (algorithms, algo_strength) and no
452 * typechecking can be done as they are all of type unsigned long, their
453 * direct usage is discouraged.
454 * Use the SSL_C_* macros instead.
