Experiment: Hash Functions with Parameters in the Cryptographic Message Syntax and S/MIME

Overview

RFC 6210, “Experiment: Hash Functions with Parameters in the Cryptographic Message Syntax and S/MIME”, is an Experimental document published in April 2011 by J. Schaad. The canonical text is published by the RFC Editor.

Abstract

New hash algorithms are being developed that may include parameters. Cryptographic Message Syntax (CMS) has not currently defined any hash algorithms with parameters, but anecdotal evidence suggests that defining one could cause major problems. This document defines just such an algorithm and describes how to use it so that experiments can be run to find out how bad including hash parameters will be. This document defines an Experimental Protocol for the Internet community.
