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

summary: 'Simple memory-only storage module'

Introduction
============

This module acts as a normal storage module for Prosody, but saves all
data in memory only. All data is lost when the server stops. This makes
it useful for testing, or certain specialized applications.

Details
=======

Because the accounts store will always begin empty, it is mostly useful
combined with an authentication plugin which doesn't use Prosody's
storage API, or with [mod\_auth\_any](mod_auth_any.html), or you can
create user accounts manually each time the server starts.

Compatibility
=============
