.NET使用OpenSSL生成的pem密钥文件(增加size为2048的密钥转换)(5)

        static string GetPemContent(string filePath)
        {
            string content = File.ReadAllText(filePath, Encoding.ASCII);
            return content;
        }
        public static void TestSignAndEncrypt(string privateKey,string publicKey)
        {
            //sign
            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("verify sign successful");
            }
            else
            {
                Console.WriteLine("verify sign failed");
            }

            //encrypt and decrypt data
            byte[] encryptedData = rsaPub.Encrypt(testData, false);
