Use of the SLH-DSA Signature Algorithm in the Cryptographic Message Syntax
RFC 9814, “Use of the SLH-DSA Signature Algorithm in the Cryptographic Message Syntax”, is a Proposed Standard document published in July 2025 by R. Housley, S. Fluhrer, P. Kampanakis, B. Westerbaan. The canonical text is published by the RFC Editor.
Abstract
SLH-DSA is a stateless hash-based signature algorithm. This document specifies the conventions for using the SLH-DSA signature algorithm with the Cryptographic Message Syntax (CMS). In addition, the algorithm identifier and public key syntax are provided.
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.
