liuliu2307/luaobfuscator

A lua obfuscator originally designed for Garry's Mod's "glua" but should work for most regular scripts.

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)
