This document defines a placeholder X.509 signature algorithm that
may be used in contexts where the consumer of the certificate is not
expected to verify the signature. As part of this, it updates RFC
5280.

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.

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
