⚙️ Obfuscation Features

The tool uses JavaScript Obfuscator with the following protection features:

代码混淆特性

• ✅ 压缩 (Compaction): Remove unnecessary whitespace and comments
• ✅ 控制流扁平化 (Control Flow Flattening): Transform code structure
• ✅ 死代码注入 (Dead Code Injection): Add meaningless code to confuse analysis
• ✅ 字符串数组 (String Array): Encode strings in arrays with transformations
• ✅ 标识符重命名 (Identifier Renaming): Use hexadecimal names
• ✅ 数字表达式 (Numbers to Expressions): Convert numbers to expressions
• ✅ 字符串分割 (String Splitting): Split strings into chunks
• ✅ 自我保护 (Self-Defending): Prevent code beautification
• ✅ 控制台禁用 (Console Output Disabled): Remove console statements

HTML 处理特性

• ✅ 内联 JavaScript 混淆: Obfuscate <script> tags without src
• ✅ 外部 JavaScript 处理: Process external JS files referenced in HTML
• ✅ HTML 压缩: Minify HTML structure
• ✅ 路径保持: Maintain relative paths for external resources

📁 File Structure After Processing

├── index.html          # Original HTML file
├── js/
│   ├── app.js         # Original JS file
│   └── utils.js       # Original JS file
└── dist/              # Output directory

    └── js/
        ├── app.js     # Obfuscated JS
        └── utils.js   # Obfuscated JS

🔧 Configuration

The obfuscator uses optimized default settings, but you can modify obfuscator.ts for custom configurations:

const jsObfuscatorOptions = {
  compact: true,
  controlFlowFlattening: true,
  deadCodeInjection: true,
  stringArray: true,
  // ... other options
};
