Adding acronyms to simplify DANE conversations
draft-ietf-dane-registry-acronyms-04

Abstract

Experience has shown that people get confused using the three numeric fields the TLSA record. This document specifies descriptive acronyms for the three numeric fields in the TLSA records. This document updates the format of the IANA registry created by RFC6698.

1. Introduction

During discussions on how to add DANE [RFC6698] technology to new protocols/services people repeatedly have got confused as to what the numeric values stand for and even the order of the fields of a TLSA record (TLSA is not an acronym but a name). This document updates the IANA registry definition for TLSA record to add a column with an acronym for each specified field, in order to reduce confusion. This document does not change the DANE protocol in any way.

It is expected that DANE parsers in applications and DNS software can adopt parsing the acronyms for each field.

2. IANA considerations

This document applies to "DNS-Based Authentication of Named Entities (DANE) Parameters" located at "http://www.iana.org/assignments/dane-parameters/dane-parameters.xhtml". Each one of the Sub-registries will add a column with an acronym for that field.

[RFC6698] and this document are both to be the reference documents for the three sub-registries.

As these acronyms are offered for human consumption, case does not matter, it is expected that software that parses TLSA records will handle upper, mixed or lower case use as input.

2.1. TLSA Certificate Usages Registry

Update reference for this registry to include both [RFC6698] and [RFC-this-document]
