RFC 9206: Commercial National Security Algorithm (CNSA) Suite Cryptography for Internet Protocol Security (IPsec)
In plain English — editorial summary, not part of the RFC
The United States Government has published the National Security Agency's Commercial National Security Algorithm (CNSA) Suite, which defines cryptographic algorithm policy for national security applications. This document specifies the conventions for using the United States National Security Agency's CNSA Suite algorithms in Internet Protocol Security (IPsec). It applies to the capabilities, configuration, and operation of all components of US National Security Systems (described in NIST Special Publication 800-59) that employ IPsec. This document is also appropriate for all other US Government systems that process high-value information. It is made publicly available for use by developers and operators of these and any other system deployments.
