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-Alpha' summary: A web interface to register user accounts rockspec: build: copy_directories: - templates ... Introduction ------------ There are various reasons to prefer web registration instead of "in-band" account registration over XMPP. For example the lack of CAPTCHA support in clients and servers. Details ------- mod\_register\_web has Prosody serve a web page where users can sign up for an account. It implements reCAPTCHA to prevent automated sign-ups (from bots, etc.). Configuration ------------- The module is served on Prosody's default HTTP ports at the path `/register_web`. More details on configuring HTTP modules in Prosody can be found in our [HTTP documentation](http://prosody.im/doc/http). To configure the CAPTCHA you need to supply a 'captcha\_options' option: captcha_options = { recaptcha_private_key = "12345"; recaptcha_public_key = "78901"; } The keys for reCAPTCHA are available in your reCAPTCHA account, visit [reCAPTCHA](https://developers.google.com/recaptcha/) for more info. If no reCaptcha options are set, a simple built in captcha is used. Customization ------------- Copy the files in mod_register_web/templates/ to a new directory. Edit them, and set `register_web_template = "/path/to/your/custom-templates"` in your config file. Compatibility ------------- ----- -------------- 0.10 Works 0.9 Works 0.8 Doesn't work ----- -------------- Todo ---- Different CAPTCHA implementation support Collection of additional data, such as email address The module kept simple!
