Certification Authority Authorization Record Extensions for Account URI and Automatic Certificate Management Environment Method Binding

Overview

RFC 8657, “Certification Authority Authorization Record Extensions for Account URI and Automatic Certificate Management Environment Method Binding”, is a Proposed Standard document published in November 2019 by H. Landau. The canonical text is published by the RFC Editor.

Abstract

The Certification Authority Authorization (CAA) DNS record allows a domain to communicate an issuance policy to Certification Authorities (CAs) but only allows a domain to define a policy with CA-level granularity. However, the CAA specification (RFC 8659) also provides facilities for an extension to admit a more granular, CA-specific policy. This specification defines two such parameters: one allowing specific accounts of a CA to be identified by URIs and one allowing specific methods of domain control validation as defined by the Automatic Certificate Management Environment (ACME) protocol to be required.

What “Proposed Standard” means

An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
