If either of us gets really bored we can add the other modes :-) FWIW, I've been honing my T4 loop assembler skills with some gmplib hacking, and I've come up with some ideas we can use to try and speed up the main openssl loops a bit. Primarily it's dealing with the minimization of bookkeeping instructions in inner loops, such that the only bookkeeping that occurs is the loop iterator adjustment and the branch. ______________________________________________________________________ OpenSSL Project http://www.openssl.org Development Mailing List openssl-dev@openssl.org Automated List Manager majord...@openssl.org
