「JS 混淆加密」是什么？What is the JavaScript Obfuscator tool?
在线混淆 JavaScript 代码，提高逆向难度，可选紧凑、字符串数组、控制流扁平化。基于 javascript-obfuscator，本地运行。Obfuscate JavaScript to make reverse-engineering harder, with compact, string-array and control-flow-flattening options. Uses javascript-obfuscator, runs locally.
如何使用「JS 混淆加密」？How do I use the JavaScript Obfuscator tool?
在「JS 混淆加密」中，先在上方输入或粘贴内容，然后点击「混淆」、「复制」按钮即可。In the JavaScript Obfuscator: Type or paste your input above, then click "Obfuscate", "Copy".
混淆等于加密吗？Is obfuscation the same as encryption?
不是。混淆让代码难以阅读，但仍可运行、理论上可被还原，不能替代真正的加密或后端保护。No. Obfuscation makes code hard to read but it still runs and can, in theory, be reversed — it's not a substitute for real encryption or server-side protection.
控制流扁平化有什么影响？What about control-flow flattening?
能显著提高逆向难度，但会让代码变大、变慢，请按需开启。It greatly raises the difficulty of reversing, but makes the code larger and slower — enable only if needed.
代码或数据会被上传吗？Is my code or data uploaded?
不会。「JS 混淆加密」完全用 JavaScript 在本地运行，适合处理含有密钥、内部接口等敏感内容的数据。No. The JavaScript Obfuscator runs entirely in local JavaScript, so it is safe for data containing keys or internal endpoints.
「JS 混淆加密」免费吗？需要注册吗？Is the JavaScript Obfuscator free? Do I need an account?
「JS 混淆加密」完全免费，无需注册或安装，打开网页即可使用，手机和电脑都能用；输入的内容只在你的浏览器本地处理。The JavaScript Obfuscator is completely free with no sign-up or install and works on phones and desktops; what you enter is processed only in your browser.
