Internet X.509 Public Key Infrastructure Certificate Request Message Format
RFC 4211, “Internet X.509 Public Key Infrastructure Certificate Request Message Format”, is a Proposed Standard document published in September 2005 by J. Schaad. It obsoletes RFC 2511. It has since been updated by RFC 9045. The canonical text is published by the RFC Editor.
Abstract
This document describes the Certificate Request Message Format (CRMF) syntax and semantics. 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 the associated registration information. This document does not define a certificate request protocol. [STANDARDS-TRACK]
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.
