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' - 'Type-Auth' summary: | Authentication module for 'HA1' hashed credentials in a text file, as used by reTurnServer ... Introduction ============ This module authenticates users against hashed credentials stored in a plain text file. The format is the same as that used by reTurnServer. Configuration ============= Name Default Description ----------------- ---------- --------------------------------- auth\_ha1\_file auth.txt Path to the authentication file Prosody reads the auth file at startup and on reload (e.g. SIGHUP). File Format =========== The file format is text, with one user per line. Each line is broken into four fields separated by colons (':'): username:ha1:host:status Field Description ---------- ---------------------------------------------------------------------------------- username The user's login name ha1 An MD5 hash of "username:host:password" host The XMPP hostname status The status of the account. Prosody expects this to be just the text "authorized" More info can be found [here](https://github.com/resiprocate/resiprocate/blob/master/reTurn/users.txt). Example ------- john:2a236a1a68765361c64da3b502d4e71c:example.com:authorized mary:4ed7cf9cbe81e02dbfb814de6f84edf1:example.com:authorized charlie:83002e42eb4515ec0070489339f2114c:example.org:authorized Constructing the hashes can be done manually using any MD5 utility, such as md5sum. For example the user 'john' has the password 'hunter2', and his hash can be calculated like this: echo -n "john:example.com:hunter2" | md5sum - Compatibility ============= ------ ------- 0.9 Works 0.10 Works ------ -------
