370 | * over time, since the export control rules are no static technical issue. | |
371 | * | |
372 | * Independent of the export flag the cipher strength is sorted into classes. | |
373 | * SSL_EXP40 was denoting the 40bit US export limit of past times, which now | |

377 | * For this reason SSL_MICRO and SSL_MINI macros are included to widen the | |
