JavaScript Obfuscator

JavaScript Obfuscator 是一款功能强大的代码混淆器，能将原始代码混淆成可读性低的代码，看上去是难以阅读的代码不过具备和之前代码一样的功能，从而起到保护代码的作用。

特性

• 重命名变量
• 字符串提取和加密
• 注入死代码
• 控制流扁平化
• 代码转换
• ……

使用示例

var JavaScriptObfuscator = require('javascript-obfuscator');

var obfuscationResult = JavaScriptObfuscator.obfuscate(
    `
        (function(){
            var variable1 = '5' - 3;
            var variable2 = '5' + 3;
            var variable3 = '5' + - '2';
            var variable4 = ['10','10','10','10','10'].map(parseInt);
            var variable5 = 'foo ' + 1 + 1;
            console.log(variable1);
            console.log(variable2);
            console.log(variable3);
            console.log(variable4);
