    lib/armeabi/libSecShell.so
    lib/armeabi/libSecShell-x86.so
    梆梆企业版
    assets/classes0.jar
    lib/armeabi-v7a/libDexHelper.so
    lib/armeabi-v7a/ libDexHelper-x86.so
    梆梆是把原dex文件加密放到了secData0.jar，所以直接拿到dex文件，修复配置文件的程序入口点就可以重打包完美运行。
    通过还原加密算法，解密secData0.jar，直接解压解密jar就是原dex。
    secData0.jar文件保存在.cache的classes.dex是加密的，主要是通过hook实现，打开时解密，关闭时加密(open、mmap)。
