This should not be a thing, I’m sorry. You’re selling an exploit as a paid service and I don’t even want to take the chance that a junior developer will fall for it.

Literally no amount of documentation is going to justify having private keys to other people’s servers.

One of the ways to fix it would be to open source ALL the code, let people self host it if they want to. You get to see your work live on atleast.
