The updates to RFC 5280 described in this document provide alignment
with the 2008 specification for Internationalized Domain Names (IDNs)
and includes support for internationalized email addresses in X.509
certificates.  The updates ensure that name constraints for email
addresses that contain only ASCII characters and internationalized
email addresses are handled in the same manner.  This document
obsoletes RFC 8399.

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
