BlitzKey - Shareware activation key system

BlitzKey is a simple activation key system designed to be used in your shareware games and applications. The user can enter they're user ID and activation key (provided by you), and the BlitzKey DLL validates it. To generate keys for your customers, BlitzKey also supplies a function to generate valid activation keys for a specific ID.

BlitzKey is free to download (dll + documentation) HERE.
The C++ source to BlitzKey is availible on request only (since I don't want any hacker to have free access to the key generation algorithm)

Using BlitzKey is simple, just call the VerifyCode() or GenerateCode() function depending on your needs. Example:

ActivationCode$ = GenerateCode("Customer Name", "[SECRET KEY CODE TO MAKE THE CODE UNIQUE TO YOUR APPLICATION]")

ok = VerifyCode("Customer Name", ActivationCode$, "[SECRET KEY CODE TO MAKE THE CODE UNIQUE TO YOUR APPLICATION]")

If Not ok Then Print "INVALID REGISTRATION CODE!!!" ...
