If your code is that sensitive, put it where nobody can get to it.

E.G. provide a client or web page for people to access some service that exposes your functionality.

That service can sit behind an external firewall and communicate with a backend server behind an internal firewall, where your sensitive code runs.

For extra measure, obfuscate that code.

This would require compromising several layers of security before getting to your code.
