Hello, Based on your description I understood you need to generate the RSA public-private key combination and create the code for signing the message and the key from the server with the RSA algorithm and generated key. I suppose the code must be wrapped into a C# class library. If you have any other requirements then I suggest to discuss. Best Regards, Patrik
