278 * Export and cipher strength information. For each cipher we have to decide
279 * whether it is exportable or not. This information is likely to change
280 * over time, since the export control rules are no static technical issue.
282 * Independent of the export flag the cipher strength is sorted into classes.
283 * SSL_EXP40 was denoting the 40bit US export limit of past times, which now
284 * is at 56bit (SSL_EXP56). If the exportable cipher class is going to change
285 * again (eg. to 64bit) the use of "SSL_EXP*" becomes blurred even more,
286 * since SSL_EXP64 could be similar to SSL_LOW.
287 * For this reason SSL_MICRO and SSL_MINI macros are included to widen the
288 * namespace of SSL_LOW-SSL_HIGH to lower values. As development of speed
289 * and ciphers goes, another extension to SSL_SUPER and/or SSL_ULTRA would

310 * Macros to check the export status and cipher strength for export ciphers.
311 * Even though the macros for EXPORT and EXPORT40/56 have similar names,
312 * their meaning is different:
313 * *_EXPORT macros check the 'exportable' status.
314 * *_EXPORT40/56 macros are used to check whether a certain cipher strength
316 * Since the SSL_IS_EXPORT* and SSL_EXPORT* macros depend on the correct
317 * algorithm structure element to be passed (algorithms, algo_strength) and no
318 * typechecking can be done as they are all of type unsigned long, their
319 * direct usage is discouraged.
320 * Use the SSL_C_* macros instead.
