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

301 * Macros to check the export status and cipher strength for export ciphers.

304 * *_EXPORT macros check the 'exportable' status.
305 * *_EXPORT40/56 macros are used to check whether a certain cipher strength
307 * Since the SSL_IS_EXPORT* and SSL_EXPORT* macros depend on the correct

309 * typechecking can be done as they are all of type unsigned long, their
310 * direct usage is discouraged.
