This package is from me and needs also some further coding for error handling. It allows to inject a wireguard instance to a server to automatize wireguard handling. Basically, it uses https to insert a public key on a server and opens up a wireguard instance and configures it also on client side. I use rpcd for doing all that so it is written in shell, and is easily extendable and can also just modified by everyone who is able to do shell scripting.
