Unfortunately MD5 cannot benefit from software pipelining because it would need the result of a (theoretical) SSE computation immediately after it is finished: MD5 has much less parallelism than SHA1. Anyway, your work on SHA1 is very interesting. -- Marc Bevand http://epita.fr/~bevand_m Computer Science School EPITA - System, Network and Security Dept. ______________________________________________________________________ OpenSSL Project http://www.openssl.org Development Mailing List [EMAIL PROTECTED] Automated List Manager [EMAIL PROTECTED]
