mod_cloud_notify_encrypted: Ensure body substring remains valid UTF-8 The `body:sub()` call risks splitting the string in the middle of a multi-byte UTF-8 sequence. This should have been caught by util.stanza validation, but that would have caused some havoc, at the very least causing the notification to not be sent. There have been no reports of this happening. Likely because this module isn't widely deployed among users with languages that use many longer UTF-8 sequences. The util.encodings.utf8.valid() function is O(n) where only the last sequence really needs to be checked, but it's in C and expected to be fast.

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
=============
