NileKey is a one-way alphanuermic encryption system that can turn any string into a 16-digit product key with unlimited variations. It also offers a lock down system and UI that can pause your entire app and enable users to enter a product key for it to unlock. It's a great way to secure your product in events, demo builds, freelance jobs, etc...

APIs
NileKey offers many public methods for you to use globally from any script. Methods for encrypting, comparing, getting system ID, saving a product key, checking if certain key has been used before and more giving you full control. Check the docs above for more info.
KEYS FOR CERTAIN DEVICE
You can generate product keys by system ID for a certain device only OR you can give your app a certain string ID of your choosing that takes product keys that compare to that string.
LOCK DOWN
A lock down system called NileKeyLock is available with the package. It renders the Lock UI and requires a product key submission by the user. Supports copy/paste. The UI can be completely styled or you can even use your own. The lock down system is also ready as a prefab so a simple drag and drop to the heirarchy is all it takes. It offers many properties and events triggering to set how you also want the Lock UI to behave.
SECURITY
The encryption algorithm is very secure and any change or fiddling to the generated product key no matter how small, leads to operation failure in the comparison. The generated product key also respects the order of the encrypted string. So for example "ABC" key != "CBA" key.
SAVING KEY & CHECKING IF KEY IS USED
You can save any product key to the system as the currently used product key and you can even check whether a certain product key has been used in the past or not. In order to prevent users from using the same product key twice on the same device.
CODE & PACKAGE
The source code is fully commented and comes with 4 demos showcasing different options like encrypting, comparing & lock down. The demo found above is inside the package too.
