Okay, `sub` seems to be a pretty standard place for user identifiers.
Let's start with that assumption! I override the `oauth2-mock-server`'s
default of `johndoe` with `theneopetsteam`, just to be cute :3
Right, I didn't totally connect the dots that there's some OpenID
features in the mix here for how we expect to identify the user once
they authenticate. It requires looking up the provider's public key,
and validating the JWT they sent us. This gem does all that for us!
I don't actually know what a real NeoPass `id_token` looks like yet?
But I'll fill in some placeholder stuff for now, and use that for
initializing the account!
I'm starting to work with the OpenID Connect stuff in NeoPass, and the
library I'm using for discovery doesn't seem to want to do it over a
plain `http://` connection. (I dug into the source files, and it just
actually is hardcoded to only work with HTTPS, as far as I can tell?)
So, I've added logic to `neopass-server` to try to make an HTTPS
certificate with the `mkcert` utility (if installed), which is a tool
that installs a root certificate authority on your local machine, then
helps you create certificates via that authority that will work only on
your local machine.
I think I'll also be able to remove the "main" server in front of the
backing server, because the library I'm using now will be able to
"discover" the auth and token endpoints, so it won't matter that our
local one uses different URLs than live NeoPass does? We'll find out!
I also remove `neopass-server` from the `Procfile`, because I think
it's a bit rude to have it auto-try to run `mkcert`. We could like,
make the process just a no-op in that case? But I think I'd prefer to
just run `neopass-server` by hand when I want it, for simplicity.
Hey nice, now we can actually get a round-trip auth success! This gets
us to the `Devise::OmniauthCallbacksController#neopass` success method,
so now we need to add our logic to actually login/signup!
