Packaging a tool to keep intellectual property safe?

I created a editor tool and I am wondering if there is a way to package it or export it without leaving the code visible to others or as a script in the editor folder in the projects window?

If this is not a feature of Unity is there a way or proper way to do something that would allow me to keep my features secure and or from being copied?

It’s completely impossible. Standard DLLs are trivial to decompile. Native code DLLs would be harder, but are much more inconvenient to make and use, and do nothing to prevent copying. There’s nothing Unity or anything else can do about this; it’s the nature of digital files.
