// AES 加密

        {
            byte[] data = Encoding.Unicode.GetBytes(text);
            SymmetricAlgorithm aes = Rijndael.Create();
            aes.Key = keyArray;
            aes.IV = keyArray;
            aes.Mode = CipherMode.CBC;
            aes.Padding = PaddingMode.Zeros;

            using (MemoryStream ms = new MemoryStream())
            {
                using (CryptoStream cs = new CryptoStream(ms, aes.CreateEncryptor(), CryptoStreamMode.Write))
                {
                    cs.Write(data, 0, data.Length);
                    cs.FlushFinalBlock();
                    byte[] cipherBytes = ms.ToArray(); // 得到加密后的字节数组
                    cs.Close();
                    ms.Close();
                    aes.Clear();
