The Cryptographic Message Syntax (CMS) supports key transport and key
agreement algorithms.  In recent years, cryptographers have been
specifying Key Encapsulation Mechanism (KEM) algorithms, including
quantum-secure KEM algorithms.  This document defines conventions for
the use of KEM algorithms by the originator and recipients to encrypt
and decrypt CMS content.  This document updates RFC 5652.

This document is a product of the Limited Additional Mechanisms for PKIX and SMIME Working Group of the IETF.

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the 
standardization state and status of this protocol.  Distribution of this 
memo is unlimited.
