I just want to write a piece of C-code to generate the same string as stored in rolpassword based on the roles password (and as I learned added the rolname), i.e. how to generate md52f128a1fbbecc4b16462e8fc8dda5cd5 from sisis123 (password) and sisis (rolename). And this, not to brute force credentials, but to understand the hash. matthias -- Matthias Apitz, ✉ guru@xxxxxxxxxxx, http://www.unixarea.de/ +49-176-38902045 Public GnuPG key: http://www.unixarea.de/key.pub
