I have no experience with cryptology. I'm seeking a module that would allow me to encrypt and decrypt a string by the same key.
I have used Digest::MD5 for mixing up some data to create a semi-unique identifier to be used as a cookie value (CGI Programming 2nd Edition), however after reading the Digest::MD5 doc I'm not sure if that module would be of any help for this chore.

Any (thoughts|tips|tricks) would be greatly appreciated.
