php-關於DES加密 求協助！

php加密des

對接方des加密 是用.net 寫的

我用的是php 就大俠把.net的加密程式幫我 轉換成 php的

下面是 .NET 的加密程式：

 public class DESEncryptDecrypt    {        private string Key;        private string IV;        private DESCryptoServiceProvider IDes;        private byte[] GetKey;        private byte[] GetIV;        public DESEncryptDecrypt()        {            this.Key = "%&hj7x89H$yuBI0456FtmaT5&fvHUFCy76*h%(HilJ$lhj!y6&(*jkP87jH7&*^$^&*%&*%$@#@^";            this.IV = "E4ghj*Ghg7!rNIfb&95GUY86GfghUb#er57HBh(u%g6HJ($jhWk7&!hg4ui%$hjk";            this.Init();        }        public DESEncryptDecrypt(string Key)        {            this.Key = Key;            this.IV = "E4ghj*Ghg7!rNIfb&95GUY86GfghUb#er57HBh(u%g6HJ($jhWk7&!hg4ui%$hjk";            this.Init();        }        public DESEncryptDecrypt(string Key,string IV)        {            this.Key = Key;            this.IV = IV;            this.Init();        }        private void Init()        {            this.IDes = new DESCryptoServiceProvider();            this.IDes.GenerateKey();            this.GetKey = this.IDes.Key;            this.IDes.GenerateIV();            this.GetIV = this.IDes.IV;        }        ///         /// 獲得密鑰        ///         /// 密鑰        private byte[] GetLegalKey()        {            string sTemp = this.Key;            byte[] bytTemp = this.GetKey;            int KeyLength = bytTemp.Length;            if (sTemp.Length > KeyLength)            {                sTemp = sTemp.Substring(0, KeyLength);            }            else            {                if (sTemp.Length < KeyLength)                {                    sTemp = sTemp.PadRight(KeyLength, ' ');                }            }            return ASCIIEncoding.ASCII.GetBytes(sTemp);        }        ///         /// 獲得初始向量IV        ///         /// 初試向量IV        private byte[] GetLegalIV()        {            string sTemp = this.Key;            byte[] bytTemp = this.GetIV;            int IVLength = bytTemp.Length;            if (sTemp.Length > IVLength)            {                sTemp = sTemp.Substring(0, IVLength);            }            else            {                if (sTemp.Length < IVLength)                {                    sTemp = sTemp.PadRight(IVLength, ' ');                }            }            return ASCIIEncoding.ASCII.GetBytes(sTemp);        }        ///         /// 密碼編譯演算法        ///         ///         ///         public string Encrypt(string data)        {            //將要加密的資料編碼為位元組數組            byte[] encrypt_data = System.Text.Encoding.UTF8.GetBytes(data);    //如果使用Unicode編碼，支援中文加密            //建立流，儲存加密後的資料            MemoryStream ms = new MemoryStream();            //建立加密流            CryptoStream cs = new CryptoStream(ms, this.IDes.CreateEncryptor(this.GetLegalKey(), this.GetLegalIV()), CryptoStreamMode.Write);            //調用Write方法將加密後的結果寫到 流 中            cs.Write(encrypt_data, 0, encrypt_data.Length);            //將資料從流寫入記憶體（這句不能少，否則在從記憶體匯出到字串的時候會出現字元丟失)            cs.FlushFinalBlock();            //ms.ToString(); ==>將流寫入位元組數組中            string result = Convert.ToBase64String(ms.ToArray());            ms.Close();            cs.Close();            return result;        }        ///         /// 解密演算法        ///         ///         ///         public string Decrypt(string data)        {            byte[] decrypt_data = Convert.FromBase64String(data);            MemoryStream ms = new MemoryStream();            CryptoStream cs = new CryptoStream(ms, this.IDes.CreateDecryptor(this.GetLegalKey(), this.GetLegalIV()), CryptoStreamMode.Write);            cs.Write(decrypt_data, 0, decrypt_data.Length);            cs.FlushFinalBlock();            string result = System.Text.Encoding.UTF8.GetString(ms.ToArray());            ms.Close();            cs.Close();            return result;        }    }
