I don't mind the wg-quick command line interface but I must say that the #1 thing that bothers me with wg is that the private keys are stored directly in the config. That means that every time I add a new users the keys are plainly readable on my screen.

Is there a simple way to work around this issue? Can I include the keys from a 3rd party file for instance? I guess I could always just pre-process the config file to generate the final one from multiple sources.
