Automatic Certificate Management Environment (ACME)
draft-ietf-acme-acme-14
Abstract
Public Key Infrastructure 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. Today, 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.
