顺藤摸瓜至java调用dll实现加密狗

最近再做一个反编译项目—-某A6企业管理软件。软件版本不详述。/

由于主要程序是封装在java程序里，jar文件多达300个，找关键词比较累，最省事的办法是，使用winrar或者360对jar文件格式进行关联，然后批量解压缩至对应目录。

经过多次的搜索，锁定“U3DogDLL”为加密狗的加载程序，

我们通过FileLocatorPortable批量文本搜索软对关键词进行检索。是那个程序调用的加密狗程序以进行尝试查看加密方式。无奈，该程序进行了混淆，混淆的工具是：

Manifest-Version: 1.0
Ant-Version: Apache Ant 1.6.5
Created-By: yGuard Bytecode Obfuscator 2.2.0

后面的Crack方法暂且不知道，结合其网站的log文件，有大量的加密字符串的请求。每天频繁读写磁盘的日志，每操作1个按钮，都会记录在2个地方，sql和网站日志。以至于服务器的磁盘撑不过3年，每天必须要定时重启mssql，否则将会卡死崩溃。这么烂的系统还搞个锁。。。RTM
