.NET使用OpenSSL生成的pem密钥文件【做电子商务的朋友可能需要】(5)

            RSAParameters para = PemConverter.ConvertFromPemPrivateKey(PRIVATEKEY);
            RSACryptoServiceProvider rsa = new RSACryptoServiceProvider();
            rsa.ImportParameters(para);
            byte[] testData = Encoding.UTF8.GetBytes("hello");
            MD5CryptoServiceProvider md5 = new MD5CryptoServiceProvider();
            byte[] signData = rsa.SignData(testData, md5);

            //verify
            RSAParameters paraPub = PemConverter.ConvertFromPemPublicKey(PUBLICKEY);
            RSACryptoServiceProvider rsaPub = new RSACryptoServiceProvider();
            rsaPub.ImportParameters(paraPub);
            if (rsaPub.VerifyData(testData, md5, signData))
            {
                Console.WriteLine("ok");
            }
            else
            {
                Console.WriteLine("no");
            }

        }

    }
}
