LuaDefender is a Lua code obfuscator designed to make your Lua code harder to read and reverse-engineer. It uses a variety of techniques to obfuscate your code, including identifier renaming, dead code injection, control flow obfuscation, arithmetic obfuscation, and boolean obfuscation.
- Identifier Renaming: All variable and function names are replaced with randomly generated names.
- Dead Code Injection: Randomly generated code that does not affect the program's behavior is inserted.
- Control Flow Obfuscation: Unnecessary conditional statements and loops are added to the code.
- Arithmetic Obfuscation: Arithmetic operations are replaced with equivalent, but more complex expressions.
- Boolean Obfuscation: 'true' and 'false' values are replaced with dynamically generated expressions that evaluate to 'true' or 'false'.
- Code Minification: Removes comments and unnecessary white spaces, and reduces the code to a single line.
- Place your Lua script in the same directory as the LuaDefender script and name it
script.lua. - Run the LuaDefender script. This will generate an obfuscated version of your script named
obfs.lua.
- The obfuscator does not currently support the obfuscation of
gotostatements. - The obfuscator may not work correctly with complex Lua scripts that use advanced features of the language.
This tool is intended for educational purposes and to increase the difficulty of reverse-engineering Lua scripts. It does not provide absolute security or protection for your code. Skilled attackers may still be able to reverse-engineer the obfuscated code.
