414 * Independent of the export flag the cipher strength is sorted into classes.
415 * SSL_EXP40 was denoting the 40bit US export limit of past times, which now
416 * is at 56bit (SSL_EXP56). If the exportable cipher class is going to change
417 * again (eg. to 64bit) the use of "SSL_EXP*" becomes blurred even more,
418 * since SSL_EXP64 could be similar to SSL_LOW.

420 * namespace of SSL_LOW-SSL_HIGH to lower values. As development of speed
421 * and ciphers goes, another extension to SSL_SUPER and/or SSL_ULTRA would
