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: 'Module for testing ad-hoc commands and dataforms rendering'
---

# Introduction

This module provides [Ad-Hoc commands][xep0050] for testing [data
form][xep0004] that includes all kinds of fields. It's meant to help
debug both Prosodys
[`util.dataforms`][doc:developers:util:dataforms] library and
clients, eg seeing how various field types are rendered.

# Configuration

Simply add it to [`modules_enabled`][doc:modules_enabled] like any
other module.

``` {.lua}
modules_enabled = {
    -- All your other modules etc
    "adhoc_dataforms_demo";
}
```

# Usage

In your Ad-Hoc capable client, first look for "Execute command". You
should see a form with various kinds of fields.

Dataforms Demo
:   A simple command that provides a dataform with every possible field
    type, suitable for testing rending of dataforms.

Multi-step command demo
:   A command that has multiple steps, suitable for testing back and
    forwards navigation.
