                 IANA Registry Updates for TLS and DTLS

Abstract

   This document describes a number of changes to TLS and DTLS IANA
   registries that range from adding notes to the registry all the way
   to changing the registration policy.  These changes were mostly
   motivated by WG review of the TLS- and DTLS-related registries
   undertaken as part of the TLS 1.3 development process.

   This document updates the following RFCs: 3749, 5077, 4680, 5246,
   5705, 5878, 6520, and 7301.

RFC 8447         IANA Registry Updates for TLS and DTLS      August 2018

1.  Introduction

   Per this document, IANA has made changes to a number of IANA
   registries related to Transport Layer Security (TLS) and Datagram
   Transport Layer Security (DTLS).  These changes were almost entirely
   motivated by the development of TLS 1.3 [RFC8446].

   The changes introduced by this document range from simple, e.g.,
   adding notes, to complex, e.g., changing a registry's registration
   policy.  Instead of listing the changes and their rationale here in
   the introduction, each section provides rationale for the proposed
   change(s).

   This document proposes no changes to the registration policies for
   TLS Alerts [RFC8446], TLS ContentType [RFC8446], TLS HandshakeType
   [RFC8446], and TLS Certificate Status Types [RFC6961] registries; the
   existing policies (Standards Action for the first three; IETF Review
