C++代码

CipherMode.ECB

TripleDESCryptoServiceProvider DES = new TripleDESCryptoServiceProvider();

MD5CryptoServiceProvider hashMD5 = new MD5CryptoServiceProvider();

DES.Key = hashMD5.ComputeHash(Encoding.UTF8.GetBytes(des3Password));

DES.Mode = CipherMode.ECB; ICryptoTransform DESDecrypt = DES.CreateDecryptor();

byte[] Buffer = Convert.FromBase64String(EncryptValue);

string result = Encoding.UTF8.GetString(DESDecrypt.TransformFinalBlock(Buffer, 0, Buffer.Length));

可以正确解密，java代码public static String EncryptString(String strText, String sKey) {
   // MD5加密
   // String md5s = EncryptMD5.getMD5(strText);
   try {
   SecureRandom random = new SecureRandom();
   byte[] bkey = (sKey.substring(0,8)).getBytes();
   DESKeySpec deskey = new DESKeySpec(bkey);
   // 创建一个密钥工厂，然后用它把DESKeyspec转换成
   SecretKeyFactory keyFactory = SecretKeyFactory.getInstance("DES");
   SecretKey securekey = keyFactory.generateSecret(deskey);
   // cipher对象实际完成加密操作
   Cipher cipher = Cipher.getInstance("DES/ECB/PKCS5Padding");

   // cipher = Cipher.getInstance("DES/ECB/PKCS5Padding");
   // 用密钥初化Cipher对象
   cipher.init(Cipher.ENCRYPT_MODE, securekey, random);
   // 现在，获取数据并加密
   // // 正式执行加密操作
   // String str = md5s + strText;
   byte[] t = strText.getBytes("UTF-8");
   byte[] bResult = cipher.doFinal(t);
   // 1、加密完byte[] 后，需要将加密了的byte[] 转换成base64保存，如：
   BASE64Encoder base64encoder = new BASE64Encoder();
   String encode=base64encoder.encode(bkey);
   return base64encoder.encode(bResult);

   } catch (Throwable e) {
   e.printStackTrace();
   }
   return null;
   }

解密报错

怎么修改啊，求大神帮忙
