 2 | 
 3 | 制作人：Blacat Recycler
 4 | 
 5 | ## 应用介绍
 6 | 
 7 | 本小程序是为了学习目的开发，针对Cocos2dx-Lua开发的安卓游戏反编译设计。用于拆包得到的Lua文件加解密，仅仅为了获取源码学习开发。禁止用于修改游戏数据进行作弊
 8 | 
 9 | ## 使用方法
10 | 
11 | 在控制台中运行，输入以下
12 | 
13 | |命令格式|作用|
14 | |:--|:---|
15 | |D(d) [fileName] \[sign] \[key]|根据输入的Sign和Key解密文件，解密文件为原文件名\+\'.lua\'|
16 | |B(b) [fileName] \[sign] \[key]|根据输入的Sign和Key加密文件，加密文件为原文件名去除\'.lua\'|
