Thanks, I think it was very unfair for you to downvote me. First of all, I am new to Perl. I had a bad experience with cgi.pm and later on decided that cause of the problem. I found cgi.pm may have a problem parsing "~" in web address field. After that i am bit careful about using any *.pm Encryption/Decryption is a tiny part of code that I am working on. I really did not want to write alot. I realized it would be useful to obtain someone's small, not so serious encryption/decryption code. If you have looked at anyother posts of mine, you would realize that I did indeed go on to explain in details. Anyhow, thanks for your help!
