This project is a stardart Oauth2 implementation (Just the auth server) It's a working in progress

This is an auth code default implementation, it uses PKCE to secure that the tokens are 
valid. This implementation does identity validation using clientSecret, if you use an SPA
this won't work because SPA's doesn't get clientSecrets (SPA's are insecure by default), but
you still can use this work to authenticate SPA's because uses PKCE
