Kind of a pointless question if you ask me... Someone capable of reversing the security of this tool is surely able to google "Decrypt rpg maker game" and click on any of the like first 25  results. Or are you telling us you got a custom encryption? :P

Hello, Redux_Soul!
This tool compiles the source code to binary that nwjs understands and packs the files into an archive (or packages), if you wish. While the tool itself brings pretty good protection, dedicated folks that know how to disassemble games will figure out how to break it open. There is not silver bullet that can make games crack proof. Still, if you want to protect it as best as possible, you can;t go wrong with it.
