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

--- labels: - 'Stage-Beta' summary: 'Register accounts via the web using invite tokens' rockspec: dependencies: - mod_invites_page - mod_password_policy - mod_register_apps build: copy_directories: - html ... Introduction ============ This module is part of the suite of modules that implement invite-based account registration for Prosody. The other modules are: - [mod_invites] - [mod_invites_adhoc] - [mod_invites_page] - [mod_invites_register] - [mod_invites_api] - [mod_register_apps] For details and a full overview, start with the [mod_invites] documentation. Details ======= mod_invites_register_web implements a web-based registration form that validates invite tokens. It also supports guiding the user through client download and configuration via mod_register_apps. There is no specific configuration for this module (though it uses the optional `site_name` to override the displayed site name. You may also set `webchat_url` to the URL of a web chat that will be linked to after successful registration. If not specified but mod_conversejs is loaded on the current host, it will default to the URL of that module. This module depends on mod_invites_page solely for the case where an invalid invite token is received - it will redirect to mod_invites_page so that an appropriate error can be served to the user. The module also depends on [mod_password_policy] (which will be automatically loaded). As a consequence of this module being loaded, the default password policies will be enforced for all registrations on the server if not explicitly loaded or configured.
