>The known string that Dragan refers to is often the hash of the password itself. The user then supplies the password, it gets hashed, and then the hash is compared with the stored hash of the password. If the hashes match then the password is ok. The VFP encryption library from Craig includes hashing functions. The hash is not reversible back to the original password.

My problem is that keys is generated outside of the application. I'll need a way to verify the validity of the keys generated. I need to give it more thoughts.
