现在我只有解密方式
代码如下

    /// <summary>
    /// AES解密
    /// </summary>
    /// <param name="text">密文</param>
    /// <param name="key">密钥,长度为16的字符串</param>
    /// <param name="iv">偏移量,长度为16的字符串</param>
    /// <returns>明文</returns>
    public static string DecodeAES(string text, string key, string iv)
    {
        RijndaelManaged rijndaelCipher = new RijndaelManaged();
        rijndaelCipher.Mode = CipherMode.CBC;
        rijndaelCipher.Padding = PaddingMode.Zeros;
        rijndaelCipher.KeySize = 128;
        rijndaelCipher.BlockSize = 128;
        byte[] encryptedData = HexStrToByte(text);// 
        //byte[] encryptedData=System.Text.UTF8Encoding.UTF8.GetBytes(text);
        byte[] pwdBytes = System.Text.UTF8Encoding.UTF8.GetBytes(key);
        byte[] keyBytes = new byte[16];
        int len = pwdBytes.Length;
        if (len > keyBytes.Length)
            len = keyBytes.Length;
        System.Array.Copy(pwdBytes, keyBytes, len);
        rijndaelCipher.Key = keyBytes;

        byte[] ivBytes = UTF8Encoding.UTF8.GetBytes(iv); //偏移向量
        byte[] ivBytesNew = new byte[16];
        len = ivBytes.Length;
        if (len > 16)
            len = ivBytesNew.Length;
        System.Array.Copy(ivBytes, ivBytesNew, len);  //复制IV16位作为密钥
        rijndaelCipher.IV = ivBytesNew;

        ICryptoTransform transform = rijndaelCipher.CreateDecryptor();
        byte[] plainText = transform.TransformFinalBlock(encryptedData, 0, encryptedData.Length);
        return UTF8Encoding.UTF8.GetString(plainText);
    }

    /// <summary>
    /// 字符串转16进制字节数组
    /// </summary>
    /// <param name="hexString"></param>
    /// <returns></returns>
    private static byte[] HexStrToByte(string hexString)
    {
        hexString = hexString.Replace(" ", "");
        if ((hexString.Length % 2) != 0)
            hexString += " ";
        byte[] returnBytes = new byte[hexString.Length / 2];
        for (int i = 0; i < returnBytes.Length; i++)
            returnBytes[i] = Convert.ToByte(hexString.Substring(i * 2, 2), 16);
        return returnBytes;
    }

加密出来的结果示例如下

用上面的方式可以解密这段代码

解密方法已经有了 我现在想知道 对应的加密方法是怎么样的
