mod_muc_rtbl: also filter messages This was a bit tricky because we don't want to run the JIDs through SHA256 on each message. Took a while to come up with this simple plan of just caching the SHA256 of the JIDs on the occupants. This will leave some dirt in the occupants after unloading the module, but that should be ok; once they cycle the room, the hashes will be gone. This is direly needed, otherwise, there is a tight race between the moderation activities and the actors joining the room.

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
