【软件名称】: XX快递单打印软件 简易版V3.5
【下载地址】: http://www.52pojie.cn/thread-519339-1-1.html
【使用工具】: OD等
【加密方式】: MD5变形
【软件介绍】: 一看就明白干什么的。
【 声 明】: 仅为算法研究，勿作它途。
看到论坛里讨论这个软件热火朝天，呵呵，我也凑凑热闹，分析它的算法，ZF0806吾是土豪做了内存机，感谢他的分享。。。

第一步：为什么要研究下机器码是怎么生成的呢，因为下面关于注册码的生成和机器码是一样的。

好高深的样子 要好好学习下！ 好厉害 羡慕会分析算法的 路过学习中。。。 不错不错，分析算法牛 谢谢！虽然用不上 不错，学习了。辛苦写这么多了 学习下，作者辛苦~~ 留名，以后或许能用的上。 还真是没看懂，过程 有些地方好象没说清楚吧
