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-Stable' summary: 'XEP-077 IBR Registration Redirect.' ... Introduction ------------ Registration Redirect as explained in the [IBR XEP](http://xmpp.org/extensions/xep-0077.html#redirect). Details ------- This module shows instructions on how to register to the server, should it be necessary to perform it through other means Out-Of-Band or not, and also let's registrations origining from ip addresses in the whitelist to go through normally. Usage ----- Copy the module file into your Prosody modules directory. The module will work "out of the box" as long as at least an admin entry is specified (see admins = {} option into prosody's documentation).These are the optional parameters you can specify into your global server/hostname configuration: registration_whitelist = { "*your whitelisted web server ip address*" } registrarion_url = "*your web registration page url*" registration_text = "Your custom instructions banner here" registration_oob = true (default) or false, in the case there's no applicable OOB method (e.g. the server admins needs to be contacted by phone) To not employ any whitelisting (i.e. registration is handled externally). no_registration_whitelist = true Compatibility ------------- ------ -------------- 0.10 Works 0.9 Works 0.8 Works 0.7 Might not work 0.6 Doesn't work 0.5 Doesn't work ------ --------------
