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' - 'Type-S2SAuth' summary: Fingerprint based s2s authentication ... Introduction ============ This module allows you to manually pin certificate fingerprints of remote servers. Details ======= Servers not listed in the configuration are not affected. Configuration ============= After installing and enabling this module, you can put fingerprints of remote servers in your config like this: ``` {.lua} s2s_auth_fingerprint_digest = "sha1" -- This is the default. Other options are "sha256" and "sha512" s2s_trusted_fingerprints = { ["jabber.org"] = "11:C2:3D:87:3F:95:F8:13:F8:CA:81:33:71:36:A7:00:E0:01:95:ED"; ["matthewwild.co.uk"] = { "FD:7F:B2:B9:4C:C4:CB:E2:E7:48:FB:0D:98:11:C7:D8:4D:2A:62:AA"; "CF:F3:EC:43:A9:D5:D1:4D:D4:57:09:55:52:BC:5D:73:06:1A:A1:A0"; }; } -- If you don't want to fall back to dialback, you can list the domains s2s_secure_domains too s2s_secure_domains = { "jabber.org"; } ``` Compatibility ============= ------- -------------- trunk Works 0.9 Works 0.8 Doesn't work ------- --------------
