🚀 NeaCrypt-JS

NeaCrypt-JS is a universal JavaScript obfuscator with SHA256 checksum validation and hybrid crypto support for both Node.js and browser environments.

✨ Features

• 🔐 String Encryption — Encrypts all string literals and template literals.
• 🔒 SHA256 Checksum Validation — Verifies code integrity at runtime using SHA256 hash comparison.
• 🔑 Hybrid Crypto Support — Automatically uses Node.js crypto or browser SubtleCrypto as available.
• 🎲 Randomized Chunk Encoding — Dynamically splits code into randomized chunks per build for stronger protection.
• ⚙️ Lightweight Dependency — Uses terser for minification with no heavy external dependencies.
• ⚡ CLI Ready — Supports npx, npm start, direct binary execution.

📦 Installation

npm install neacrypt-js

🛠 Usage

npx neacrypt-js --file <source> --output <output>

Example:

npx neacrypt-js --file ./test.js --output ./test.fus.js

or

npx neacrypt-js --file ./test.js --output ./test.fus.js
npx neacrypt-js --file "/path/js/index.js" --output "/path/js/index.obf.js"

⚠️ Important Note

If your code needs to expose global functions (e.g. for onclick), define them as window.functionName = function() {} before obfuscation so they remain accessible after obfuscation.
