    using (RSACryptoServiceProvider RSA = new RSACryptoServiceProvider())

        //Export the key information to an RSAParameters object. 
        //Pass false to export the public key information or pass 
        //true to export public and private key information.
        RSAParameters RSAParams = RSA.ExportParameters(false);
