A static unpacker / deobfuscator for that Lua obfuscator called "filesecuring" / "xor". This obfuscator was mainly used in FiveM communities, due to the way it detects load=print, it was pretty difficult to dump it by hooking lua functions. They recently discontinued and opensourced their obfuscator, so I can publicly release my deobfuscator for it.
Usage: build the project. run CLI.exe with following arguments:
CLI.exe input.lua
It will create an input_unpacked.lua in the same directory
