RFC 9765: RADIUS/1.1: Leveraging Application-Layer Protocol Negotiation (ALPN) to Remove MD5

In plain English — editorial summary, not part of the RFC

This document defines Application-Layer Protocol Negotiation (ALPN) extensions for use with RADIUS/TLS and RADIUS/DTLS. These extensions permit the negotiation of an application protocol variant of RADIUS called "RADIUS/1.1". No changes are made to RADIUS/UDP or RADIUS/TCP. The extensions allow the negotiation of a transport profile where the RADIUS shared secret is no longer used, and all MD5-based packet authentication and attribute obfuscation methods are removed. This document updates RFCs 2865, 2866, 5176, 6613, 6614, and 7360.
