JSBox - JavaScript Obfuscator

A simple JavaScript obfuscator built with Node.js.

Features

• Identifier Renaming: Renames variables and functions to short, meaningless names.
• String Encryption: Encodes string literals to hex escape sequences.
• Multi-Pass Obfuscation: Run obfuscation multiple times for added security.
• Auto-Minimization: Automatically minimizes the output code.
• Web UI: A Next.js based web interface for easy obfuscation.

Installation

npm install
# For Web UI
cd web
npm install

Usage

CLI

node src/index.js <input-file> [options]

Options

• -o, --output <file>: Output file path.
• -n, --passes <number>: Number of obfuscation passes (1-4).
• --no-minify: Disable auto-minimization.
• --anti-debug: Enable anti-debugging protections.
• --key <licenseKey>: Protect the script with a Key System.
• --webhook <url>: Enable Discord Webhook logging.
• --lock-domain <domains>: Comma-separated list of domains to lock the script to.
• --self-defending: Enable self-defending mechanism (anti-tamper).
• --control-flow-flattening: Enable control flow flattening (makes code structure harder to read).
• --extreme: Enable Extreme Mode (high passes, massive junk injection).
• --iife: Wrap code in an IIFE to prevent global scope pollution (Console friendly).

Example

node src/index.js test.js -o obfuscated.js -n 10 --key SECRET-123 --control-flow-flattening --extreme --iife
