Hey Richard

here’s what I see

# openssl help
openssl:Error: 'help' is an invalid command.

rc5-ecb           rc5-ofb           seed              seed-cbc
seed-cfb          seed-ecb          seed-ofb          zlib


so I do see md5 in the list of digests

what else should I be looking at ? 
is there a way to get some sort of error code or something that would at least hint at a direction..

thanks — Thierry
