1、类中的秘钥key跟向量iv，均用的同样的值

2、编码均采用的utf-8

以下为具体代码，可以直接复制去进行实际测试

C#版代码：

using System; using System.Data; using System.Configuration; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; using System.Data.SqlClient; using System.Security.Cryptography; using System.IO; using System.Text; //C# 版DES 加解密算法类public class Des{ //加解密密钥 private static string skey = "12345678";#region DESEnCode DES加密 public static string DESEnCode(string pToEncrypt, string sKey) { pToEncrypt = HttpContext.Current.Server.UrlEncode(pToEncrypt); DESCryptoServiceProvider des = new DESCryptoServiceProvider(); byte[] inputByteArray = Encoding.GetEncoding("UTF-8").GetBytes(pToEncrypt); des.Key = ASCIIEncoding.ASCII.GetBytes(sKey); des.IV = ASCIIEncoding.ASCII.GetBytes(sKey); MemoryStream ms = new MemoryStream(); CryptoStream cs = new CryptoStream(ms, des.CreateEncryptor(), CryptoStreamMode.Write);cs.Write(inputByteArray, 0, inputByteArray.Length); cs.FlushFinalBlock();StringBuilder ret = new StringBuilder(); foreach (byte b in ms.ToArray()) { ret.AppendFormat("{0:X2}", b); } ret.ToString(); return ret.ToString(); } #endregion #region DESDeCode DES解密public static string DESDeCode(string pToDecrypt, string sKey){DESCryptoServiceProvider des = new DESCryptoServiceProvider();byte[] inputByteArray = new byte[pToDecrypt.Length / 2];for (int x = 0; x < pToDecrypt.Length / 2; x++){int i = (Convert.ToInt32(pToDecrypt.Substring(x * 2, 2), 16));inputByteArray[x] = (byte)i;} des.Key = ASCIIEncoding.ASCII.GetBytes(sKey);des.IV = ASCIIEncoding.ASCII.GetBytes(sKey);MemoryStream ms = new MemoryStream();CryptoStream cs = new CryptoStream(ms, des.CreateDecryptor(), CryptoStreamMode.Write);cs.Write(inputByteArray, 0, inputByteArray.Length);cs.FlushFinalBlock(); StringBuilder ret = new StringBuilder(); return HttpContext.Current.Server.UrlDecode(System.Text.Encoding.Default.GetString(ms.ToArray()));} #endregion }

PHP版代码：

key = $key;$this->iv = $key; //默认以$key 作为 iv}//加密function encrypt($str) {$size = mcrypt_get_block_size ( MCRYPT_DES, MCRYPT_MODE_CBC );$str = $this->pkcs5Pad ( $str, $size );return strtoupper( bin2hex( mcrypt_cbc(MCRYPT_DES, $this->key, $str, MCRYPT_ENCRYPT, $this->iv ) ) );}//解密function decrypt($str) {$strBin = $this->hex2bin( strtolower( $str ) );$str = mcrypt_cbc( MCRYPT_DES, $this->key, $strBin, MCRYPT_DECRYPT, $this->iv );$str = $this->pkcs5Unpad( $str );return $str;}function hex2bin($hexData) {$binData = "";for($i = 0; $i strlen ( $text ))return false;if (strspn ( $text, chr ( $pad ), strlen ( $text ) - $pad ) != $pad)return false;return substr ( $text, 0, - 1 * $pad );}}header("Content-type: text/html; charset=utf-8");$key = 12345678;$str = abc.123;$des = new DES($key);$str_en_des = $des->encrypt($str); //加密字符串$str_de_des = $des->decrypt($str_en_des); //解密字符串echo 加密字符串：,$str,
