      How complex does it have to be? You could use a simple character replacement method, based on a string provided by the user or some other source.

        Where does the requirement that you do it from scratch come from? Its 99.99% likely that if you write your own algorithm it won't last 15 minutes of cryptanalysis....

          Got your message. Does not have to be complex a simple encryption algorithm to encrypt and decrypt files. The button sub routine will contain the algo when the user clicks the button the file gets encrypted. ;) ;) ;)
