Lua desobfuscation

Question

I was checking some Lua source, trying to get and learn from them, but it seems there are encoded & obsfuscated.

I decoded it using base64 decode, but still unreadable.

Is there any ways to desobfuscate it?

Answer 1

This is compiled lua source. You can use this tool to decompile. It isn't actually obfuscated.

Answer 2

This is a precompiled Lua 5.2 script.

You can see its contents with luac -l -p foo.

Make sure you use luac from Lua 5.2. If in doubt, try luac -v.

Answer 3

Sure: luadec

Just curious, why did you tried base64? That chunk you provided is a simple lua code, translated to lua vm bytecodes. it is not even obfuscated.
