Sorry, but your problem description is a little too vague to make it clear what you need. Is this some kind of CGI script or similar that people log in to? Or does the script use this password to log in to something else, like a database? In either case, you'll need to describe the login mechanism in more detail, in case some specific hashing algorithm is needed. A code sample would be good too (of course replacing the plaintext password with something else).

To get you started, there's crypt (although I think I remember reading somewhere that the algorithm is not necessarily secure, I'm not sure), Digest::MD5, Digest::SHA, and quite a few more, depending on what you need.
