I think it is useful but depends on what you want to protect and from who. If you want to stop the average user Cryptor is ok. If you want to stop a knowledgeable hacker then it wont be good enough. On the other hand, even if Cryptor used AES the hacker would then go after the VFP program code itself, or attack the memory. Once you install the data on the client side then the truth is that all bets are off.
