Algorithm Requirements Update to the Internet X.509 Public Key Infrastructure Certificate Request Message Format
RFC 9045, “Algorithm Requirements Update to the Internet X.509 Public Key Infrastructure Certificate Request Message Format”, is a Proposed Standard document published in June 2021 by R. Housley. It updates RFC 4211. The canonical text is published by the RFC Editor.
Abstract
This document updates the cryptographic algorithm requirements for the Password-Based Message Authentication Code in the Internet X.509 Public Key Infrastructure Certificate Request Message Format (CRMF) specified in RFC 4211.
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.
