Check the docs above for more info.KEYS FOR CERTAIN DEVICEYou 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 DOWNA 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.SECURITYThe 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 USEDYou 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 & PACKAGEThe 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.Consider leaving your feedback and tell us what you think.For support, questions or reporting bugs, contact me by email or Discord.Best of luck.
