The Module-Lattice-Based Key-Encapsulation Mechanism (ML-KEM) is a
quantum-resistant Key Encapsulation Mechanism. This document
specifies the conventions for using the ML-KEM in X.509 Public Key
Infrastructure. The conventions for the subject public keys and
private keys are also specified.

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.
