一.环境安装

在nodejs官网下载最新稳定版并安装:

下载地址:

https://nodejs.org/en/

安装成功后，在命令行模式输入 node，如果有版本号显示，则表示安装成功。

二.下载项目

项目地址:

https://github.com/Tsaiboss/decodeObfuscator

目录结构如下:

• input文件夹，   存放ob混淆代码;

• output文件夹，存放还原后的代码;

• tools,存放打包的babel库以及部分还原的AST插件;

• main.js   运行主文件;

三.运行看结果

下载后解压，切换到 decodeObfuscator-main 目录，命令行模式下运行:

node main.js

运行时，会打印一些日志，结果文件在output文件夹，打开后是这样的:

四.其它混淆代码

打开 obfuscator 官网：

https://obfuscator.io/

如图选择 Medium 级别，再点击上面的 Obfuscate 按钮，生成混淆代码:

我这里生成的混淆代码是这样的:

把上面的混淆代码保存为js文件(命名为Medium.js)，并编码为UTF-8模式。存放在 main.js 统一目录，运行命令:

node main.js Medium.js

运行后，同样可以在 output 文件夹看到还原后的结果。

当然，你还可以指定生成的文件名，如下命令:

node main.js Medium.js 666.js

可以发现，在main.js的同级目录新生成了一个 666.js文件，这就是还原后的文件。

好了，脚本的使用就介绍到这里，希望各位大佬们不要吝惜你的star，帮忙点一个，感谢！
