336 * Export and cipher strength information. For each cipher we have to decide
337 * whether it is exportable or not. This information is likely to change
338 * over time, since the export control rules are no static technical issue.
340 * Independent of the export flag the cipher strength is sorted into classes.

342 * is at 56bit (SSL_EXP56). If the exportable cipher class is going to change
343 * again (eg. to 64bit) the use of "SSL_EXP*" becomes blurred even more,
344 * since SSL_EXP64 could be similar to SSL_LOW.
345 * For this reason SSL_MICRO and SSL_MINI macros are included to widen the

347 * and ciphers goes, another extension to SSL_SUPER and/or SSL_ULTRA would
