mod_http_oauth2: Advertise the currently supported id_token signing algorithm This field is REQUIRED. The algorithm RS256 MUST be included, but isn't because we don't implement it, as that would require implementing a pile of additional cryptography and JWT stuff. Instead the id_token is signed using the client secret, which allows verification by the client, since it's a shared secret per OpenID Connect Core 1.0 § 10.1 under Symmetric Signatures. OpenID Connect Discovery 1.0 has a lot of REQUIRED and MUST clauses that are not supported here, but that's okay because this is served from the RFC 8414 OAuth 2.0 Authorization Server Metadata .well-known endpoint!

summary: 'Block remote servers via ad-hoc command'
...

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

This module provides the *Edit Blacklist* ad-hoc command described in
[XEP-0133](http://xmpp.org/extensions/xep-0133.html#edit-blacklist) and
also performs the actual blocking of incoming and outgoing
server-to-server connections.

Using
=====

In your client, simply select the Edit Blacklist command from the list
of adhoc commands. E.g. in Pidgin, this is under *Accounts -\> (your
account)* in the menu.
