Automatic Certificate Management Environment

Overview

RFC 8555, “Automatic Certificate Management Environment”, is a Proposed Standard document published in March 2019 by R. Barnes, J. Hoffman-Andrews, D. McCarney, J. Kasten. The canonical text is published by the RFC Editor.

Abstract

Public Key Infrastructure using X.509 (PKIX) certificates are used for a number of purposes, the most significant of which is the authentication of domain names. Thus, certification authorities (CAs) in the Web PKI are trusted to verify that an applicant for a certificate legitimately represents the domain name(s) in the certificate. As of this writing, this verification is done through a collection of ad hoc mechanisms. This document describes a protocol that a CA and an applicant can use to automate the process of verification and certificate issuance. The protocol also provides facilities for other certificate management functions, such as certificate revocation.

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.
