Documentation

Welcome to Nighty Script Obfuscator documentation. This tool provides powerful obfuscation techniques specifically designed for Roblox Lua scripts, helping developers protect their intellectual property.

Latest Version: 2.0.0 | Last Updated: December 2024

Core Features

Variable Renaming

Automatically renames local variables to unreadable names while preserving functionality.

ASCII Encoding

Converts string literals to ASCII character codes, making them harder to read.

XOR Encryption

Applies XOR encryption to strings with runtime decryption for enhanced security.

Code Minification

Removes all unnecessary whitespace and comments, compressing code to a single line.

Quick Start Guide

Follow these simple steps to obfuscate your first script:

1. Paste your Lua script in the Source Code editor
2. Select desired obfuscation options
3. Click "Obfuscate Now"
4. Copy or download the protected code
Important: Always test obfuscated scripts thoroughly before deployment. Keep backups of your original source code.

Variable Renaming

This feature identifies and renames all local variables in your script to randomized, meaningless names. Global variables and Roblox API calls remain untouched. 

-- Original
local player = game.Players.LocalPlayer
local health = 100

-- Obfuscated
local _a2f4x = game.Players.LocalPlayer
local _b9k2m = 100

XOR Encryption

XOR encryption adds an additional layer of protection by encrypting string literals. A decryption function is automatically injected into your script.

Feature Without XOR With XOR
String Visibility Readable Encrypted
File Size Normal +20-30%
Performance Impact None Minimal

Known Limitations

  • Does not obfuscate global variables to maintain Roblox API compatibility
  • Cannot protect against memory inspection at runtime
  • Obfuscation may increase script size depending on options selected
  • Some complex string patterns might not be correctly processed

Frequently Asked Questions

Is this 100% secure?

No obfuscation is 100% secure. This tool makes reverse engineering significantly harder but not impossible.

Will it affect performance?

Minimal impact. XOR decryption adds slight overhead on first run, but it's negligible for most scripts.

Can I obfuscate already obfuscated code?

Not recommended. It may break the script and provides no additional security benefit.

Does it work with all Roblox scripts?

Yes, it's designed specifically for Roblox Lua and preserves all Roblox API calls.
