ACME Integrations
draft-friel-acme-integrations-01
Abstract
This document outlines multiple advanced use cases and integrations
that ACME facilitates without any modifications or enhancements
required to the base ACME specification. These use cases are not
immediately obvious from reading the ACME specification and thus are
explicitly documented here. The use cases include ACME issuance of
subdomain certificates, and ACME integration with EST and TEAP.

1. Introduction
ACME [RFC8555] defines a protocol that a certificate authority (CA)
and an applicant can use to automate the process of domain name
ownership validation and X.509 (PKIX) certificate issuance. The
protocol is rich and flexible and enables multiple use cases that are
not immediately obvious from reading the specification. This
document explicitly outlines multiple advanced ACME use cases
including:
o ACME issuance of subdomain certificates
o ACME integration with EST [RFC7030]
o ACME integration with BRSKI
[I-D.ietf-anima-bootstrapping-keyinfra]
o ACME integration with TEAP [RFC7170]
o ACME integration with TEAP-BRSKI draft-lear-eap-teap-brski
2. Terminology
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
"OPTIONAL" in this document are to be interpreted as described in BCP
14 [RFC2119] [RFC8174] when, and only when, they appear in all
capitals, as shown here.
