mod_http_oauth2: Implement stateless dynamic client registration
Replaces previous explicit registration that required either the
additional module mod_adhoc_oauth2_client or manually editing the
database. That method was enough to have something to test with, but
would not probably not scale easily.
Dynamic client registration allows creating clients on the fly, which
may be even easier in theory.
In order to not allow basically unauthenticated writes to the database,
we implement a stateless model here.
per_host_key := HMAC(config -> oauth2_registration_key, hostname)
client_id := JWT { client metadata } signed with per_host_key
client_secret := HMAC(per_host_key, client_id)
This should ensure everything we need to know is part of the client_id,
allowing redirects etc to be validated, and the client_secret can be
validated with only the client_id and the per_host_key.
A nonce injected into the client_id JWT should ensure nobody can submit
the same client metadata and retrieve the same client_secret

prosody-modules =============== *Add-on modules for Prosody IM Server* -------------------------------------------------------------------------- Community repository for non-core, unofficial and/or experimental plugins for [Prosody][]. If you are a developer and would like to host your Prosody module in this repository, or want to contribute to existing modules, simply introduce yourself and request commit access on our [mailing list][]. Notes for users ---------------- There are lots of fun and exciting modules to be found here, we know you'll like it. However please note that each module is in a different state of development. Some are proof-of-concept, others are quite stable and ready for production use. Be sure to read the wiki page of any module before installing it on your server. We are working on methods to easily download and install modules from this repository. In the meantime most modules are either a single file and easy to install, or contain installation instructions on their wiki page. You can browse the files stored in this repository at <https://hg.prosody.im/prosody-modules>. [Prosody]: https://prosody.im/ [mailing list]: https://prosody.im/discuss
