1. Abstract

This document describes the Certificate Request Message Format (CRMF). This syntax is used to convey a request for a certificate to a Certification Authority (CA) (possibly via a Registration Authority (RA)) for the purposes of X.509 certificate production. The request will typically include a public key and associated registration information.

The key words "MUST", "REQUIRED", "SHOULD", "RECOMMENDED", and "MAY" in this document (in uppercase, as shown) are to be interpreted as described in RFC 2119.
