调试易

其实很多都是对的，你没找到而已。你看下这个可以不

自己调用吧 private static Byte[] KEY_64
        {            get
            {                 return new byte[] { 40, 52, 159, 81, 79, 137, 99, 82 };
                 
            }        }        private static Byte[] IV_64
        {            get
            {
                 
                return new byte[] { 98, 55, 32, 117, 156, 60, 59, 81 };
                            }        }
        public static string EncryptCookie(string name)// DES加密  关键字、数据加密
        {            //#region DES加密算法            if (name != "")
            {                DESCryptoServiceProvider cryptoProvider = new DESCryptoServiceProvider();                MemoryStream ms = new MemoryStream();                CryptoStream cs = new                    CryptoStream(ms, cryptoProvider.CreateEncryptor(KEY_64, IV_64), CryptoStreamMode.Write);                StreamWriter sw = new StreamWriter(cs);                sw.Write(name);                sw.Flush();                cs.FlushFinalBlock();                ms.Flush();                                return Convert.ToBase64String(ms.GetBuffer(), 0, Int32.Parse(ms.Length.ToString()));            }            else
            {                return "";            }                    }
    
        public static string DecryptCookie(string temp)// DES解密
        {
            try
            {
                //#region DES 解密算法                if (temp != "")
                {                    DESCryptoServiceProvider cryptoProvider = new DESCryptoServiceProvider();                    //从字符串转换为字节组                    Byte[] buffer = Convert.FromBase64String(temp);                    MemoryStream ms = new MemoryStream(buffer);                    CryptoStream cs = new                        CryptoStream(ms, cryptoProvider.CreateDecryptor(KEY_64, IV_64), CryptoStreamMode.Read);                    StreamReader sr = new StreamReader(cs);                    return sr.ReadToEnd();                }                else
                {                    return "";                }
            }            catch (Exception ex)
            {                return ex.Message;
            }        }

 这个不行的-.-  我的key是134afd8980cd0eb0  

我的解密只有KEY  我把KEY的值赋给IV， 但是到最后一步就会报错 不正确的数据。 我的key是134afd8980cd0eb0，密文是0935203713c26dd617940a593367ead4393cc44e93fe19421a127f9688d664da2f8b010c6ce2a2269f92ffe1685f50d67fcd1291d9d3453187db2a605f8a1609

问题解决了。是C#  加密解密需要一个IV，而JAVA加密的时候 是没有这个向量的。不过也谢谢各位
