alright, I ll share my bit as well. Since Ktor doesnt (yet) support server on Native, I m creating a library for simple multithreaded http server, based on pure sockets, with dsl for definition of routing. it aleeady supports base64url encoding, rsa key pair and jwt token generation and jwks key sharing.. it is still in draft stage, but it is usable. you can take a look if you are interested. I ll be happy for any feedback/contrib:
