<title>Enhanced Security Services (ESS) Update: Adding CertID Algorithm Agility</title>

<date year="2007" month="August"/>
<abstract><t>In the original Enhanced Security Services for S/MIME document (RFC 2634), a structure for cryptographically linking the certificate to be used in validation with the signature was introduced; this structure was hardwired to use SHA-1.  This document allows for the structure to have algorithm agility and defines a new attribute for this purpose.  [STANDARDS-TRACK]</t></abstract>
