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

413 * Independent of the export flag the cipher strength is sorted into classes.
414 * SSL_EXP40 was denoting the 40bit US export limit of past times, which now
415 * is at 56bit (SSL_EXP56). If the exportable cipher class is going to change
416 * again (eg. to 64bit) the use of "SSL_EXP*" becomes blurred even more,
417 * since SSL_EXP64 could be similar to SSL_LOW.
418 * For this reason SSL_MICRO and SSL_MINI macros are included to widen the
419 * namespace of SSL_LOW-SSL_HIGH to lower values. As development of speed
420 * and ciphers goes, another extension to SSL_SUPER and/or SSL_ULTRA would

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