Crypto API is an API that you can use to encrypt/decrypt data within the Windows environment. The FFC (FoxPro Foundation Classes) that will deal with the Crypto API that Randy is talking about, is not out yet but should come out with VFP7.

I'm sorry I can't give you examples of the Crypto API as I have not used it myself but searching for it in the MS pages might get you examples, most probably not written in VFP but maybe in VB which should be easy to translate.
