Subject: Who can hack this one?

This is further to a previous thread in which Leonid Lepin met my challenge to pick passwords out of "protected" VFP applications.

This link: http://www.po-dunk.com/Encrypt.zip contains a protected VFP app using an unusual protection technique. The archive contains some required dlls but not the VFP runtimes in the expectation that people will run it on VFP machines. The challenge is to give me the original VFP sourcecode- something that is surprisingly easy to achieve with other VFP "protection" techniques. This is a simple app with a textbox, a button and a code that gets calculated from the textbox when the button is pressed. Obviously it's a lot simpler than your average app, but the purpose is to see whether this sort of "protection" does a better job than prevalent schemes out there.
