php 代码保护利器－清如许工作室代码保护器

PHP程序虽然，可以使用zend 加密，不过现在都可以轻易破解。

清如许工作室，发布PHP代码加密工具，现已开源核心代码如下：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.IO;
using System.Security.Cryptography;
using System.Threading;
using System.Linq;

可以实现功能，变量名加密，true flase 数字加密。以后会有更好用的版本。来保护广告开发人员的。
