Hi!

I created an issue (#70) and PR for expanding the SafeAPI to support other =
protocol layers beyond the application layer as discussed at IETF 123.


Best regards,

Xisen Tian

Subject: WG Last Call: draft-ietf-mls-extensions-08 (Ends 2025-09-18)

This message starts a 2-week WG Last Call for this document.

Abstract:
   The Messaging Layer Security (MLS) protocol is an asynchronous group
   authenticated key exchange protocol.  MLS provides a number of
   capabilities to applications, as well as several extension points
   internal to the protocol.  This document provides a consolidated
   application API, guidance for how the protocol's extension points
   should be used, and a few concrete examples of both core protocol
   extensions and uses of the application API.

Subject: WG Last Call: draft-ietf-mls-extensions-08 (Ends 2025-09-18)<br>
<br>
This message starts a 2-week WG Last Call for this document.<br>
<br>
Abstract:<br>
&nbsp;&nbsp; The Messaging Layer Security (MLS) protocol is an asynchronous=
 group<br>
&nbsp;&nbsp; authenticated key exchange protocol.&nbsp; MLS provides a numb=
er of<br>
&nbsp;&nbsp; capabilities to applications, as well as several extension poi=
nts<br>
&nbsp;&nbsp; internal to the protocol.&nbsp; This document provides a conso=
lidated<br>
&nbsp;&nbsp; application API, guidance for how the protocol's extension poi=
nts<br>
&nbsp;&nbsp; should be used, and a few concrete examples of both core proto=
col<br>
&nbsp;&nbsp; extensions and uses of the application API.<br>
