JS-OBF - JavaScript Obfuscator

JS-OBF is a simple yet effective JavaScript obfuscation tool designed to help protect your JavaScript code from unauthorized access, analysis, or tampering. This tool allows you to obfuscate your JavaScript code by reading configuration options from a JSON file, obfuscating the input JavaScript file, and then saving the obfuscated code to a new file.

Features

• Obfuscate JavaScript Code: Easily obfuscate any JavaScript code.
• Customizable Options: Configure the obfuscation process using an external JSON file.
• CLI-based: Command-line interface for simplicity and flexibility.

Requirements

• Node.js: This tool is built using Node.js. Make sure you have it installed on your system.
• JavaScript Obfuscator: The tool uses the javascript-obfuscator package to perform the obfuscation.

Installation

To get started with JS-OBF, follow these steps:

1. Clone this repository:

   git clone https://github.com/infallibless/js-obf.git
   cd js-obf

2. Install the required dependencies:

   npm install

Usage

To obfuscate a JavaScript file, use the following command in the terminal:

node obfuscator.js <inputfile> <outputfile> <optionfile>

• <inputfile>: The JavaScript file you want to obfuscate. (default: x.txt)
• <outputfile>: The name of the obfuscated file to be generated. (default: obf.js)
• <optionfile>: The JSON configuration file that defines the obfuscation options. (default: options.json)

Example

node obfuscator.js input.js obfuscated.js options.json

This will obfuscate input.js using the settings defined in options.json and save the result to obfuscated.js.

Configuration (options.json)

You can customize the obfuscation behavior by defining various options in a JSON configuration file. Here’s an example of what the options.json file might look like:

{
    "compact": true,
    "controlFlowFlattening": true,
    "controlFlowFlatteningThreshold": 1,
    "deadCodeInjection": true,
    "deadCodeInjectionThreshold": 0.4,
    "debugProtection": true,
    "debugProtectionInterval": 1000,
    "identifierNamesGenerator": "mangled",
    "identifierNamesBlacklist": ["pedo", "child"],
    "numbersToExpressions": true,
    "renameGlobals": false,
    "rotateStringArray": true,
    "stringArray": true,
    "stringArrayEncoding": ["base64"],
    "stringArrayThreshold": 0.75,
    "simplify": true,
    "selfDefending": true,
    "sourceMap": true,
    "sourceMapMode": "separate",
    "unicodeEscapeSequence": false
}
