LuaObfuscator

This lua obfuscator was originally designed for Garry's Mod, but should work on vanilla lua. Written for private use in January 2016. I never did anything with it so I decided to put it on GitHub.

Requirements

• Python 3.4.3+ (VERY IMPORTANT)

Optional Things

• pyperclip (pip install pyperclip)

Usage

python __main__.py [--input input.lua] [--output output.lua] [--level 1] [--dontcopy] [--debug]

The default values are shown above.

If you don't want the code copied to your clipboard, use --dontcopy.

If your script is not running correctly, use --debug and you may find the issue.

Levels

Passed with the --level x argument.

Lvl | Info -----|---------------------------------------------------------------------------- 0 | Original strings, should be very similar in size to input file 1 | Creates a small file, less not as good as Lvl 2 2| Creates a small file, recommended level 3 | Invisible strings, huge files that appear to be very small, not recommended!

Features

• Code is tokenized and kind of understood
• Strings are stripped, ciphered and replaced
• Code rearrangement while retaining functionality
• All variables, local and global, are understood and replaced
• Renaming of variables defined in for loops
• Basic understanding of code heirarchy

Known issues

• Garry's Mod Lua adds // comments, which conflicts with Lua 5.3's floor division operator. Code using the floor division operator should be changed to something like math.floor(a/b)
