This package 'Serial number license' is designed to protect products by binding the product to hardwareID using serial numbers (DSA signature)

The package is included in itself

- An example of embedding verification of serial numbers (licenses) in the code of the application (game)

- Interface for generating serial numbers (licenses)

Functionality:

- Generation of serial numbers based on the DSA algorithm

- Generation of serial numbers based on a simple algorithm of an asymmetric signature

- Binding a serial number to an apartment identifier

- Support for the expiration of the serial number
