OK. its good for Encoding as in changing forms but not hiding from other readers. I think i get the difference. Encode does not imply any secrecy or privacy where as encrypt does.
Right.
Aside [ I looked encode and cryptography (encrypt wasn't in my webster collegiate paperback)
You used paper? Did someone break Google? :) http://www.google.com/search?q=define%3Aencode http://www.google.com/search?q=define%3Aencrypt
For a detailed discussion of encryption and Perl, pick up O'Reilly's Mastering Algorithms with Perl. It's a good book, with a whole chapter discussing encryption.
