428 * Export and cipher strength information. For each cipher we have to decide
429 * whether it is exportable or not. This information is likely to change

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

464 * Macros to check the export status and cipher strength for export ciphers.
465 * Even though the macros for EXPORT and EXPORT40/56 have similar names,
466 * their meaning is different:
467 * *_EXPORT macros check the 'exportable' status.
468 * *_EXPORT40/56 macros are used to check whether a certain cipher strength
470 * Since the SSL_IS_EXPORT* and SSL_EXPORT* macros depend on the correct
471 * algorithm structure element to be passed (algorithms, algo_strength) and no
472 * typechecking can be done as they are all of type unsigned long, their
473 * direct usage is discouraged.
474 * Use the SSL_C_* macros instead.
