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