To encrypt the string, looks like you pass the user defined message and password into the php program string.php with the action to 'encode' via the url. The php program then writes out the encrypted 'string' to a web page of which you read (GetWebPageContents). (e.g. http://www.issackelly.com/string.php?action=enc... ) Then, using a similar process you call http://www.issackelly.com/string.php?action=dec...

What I was getting at was 'which method do I use (inside the php script) to encrypt the string?

It's a pretty simple one; for anyone with any sort of crypto experience.
