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: 'Disable access control for all OMEMO related PEP nodes' --- Introduction ============ Traditionally OMEMO encrypted messages could only be exchanged after gaining mutual presence subscription due to the OMEMO key material being stored in PEP. XEP-0060 defines a method of changing the access model of a PEP node from `presence` to `open`. However Prosody does not yet support access models on PEP nodes. This module disables access control for all OMEMO PEP nodes (=all nodes in the namespace of `eu.siacs.conversations.axolotl.*`), giving everyone access to the OMEMO key material and allowing them to start OMEMO sessions with users on this server. Disco feature ============= This modules annouces a disco feature on the account to allow external tools such as the [Compliance Tester](https://conversations.im/compliance/) to check if this module has been installed. Compatibility ============= ----- ----------------------------------------------------------------------------- trunk Not needed, mod\_pep provides this feature already 0.11 Not needed, mod\_pep provides this feature already 0.10 Works ----- -----------------------------------------------------------------------------
