ESSCertIDv2 Update for RFC 3161
Abstract
This document updates RFC 3161. It allows the use of ESSCertIDv2, as
defined in RFC 5035, to specify the hash of a signer certificate when
the hash is calculated with a function other than the Secure Hash
Algorithm (SHA-1).

1. Introduction
The time-stamping protocol defined in RFC 3161 [RFC3161] requires
that the Cryptographic Message Syntax (CMS) SignedData [RFC5652],
used to apply a digital signature on the time-stamp token, include a
signed attribute that identifies the signer's certificate.
This identifier only allows SHA-1 [SHA1] to be used as the hash
algorithm to generate the identifier value.
The mechanism used in [RFC3161] employed ESSCertID from RFC 2634
[ESS]. RFC 5035 [ESSV2] updated ESSCertID with ESSCertIDv2 to allow
the use of any hash algorithm.
The changes to RFC 3161 [RFC3161] defined in this document allow
ESSCertIDv2 to be used to include an identifier of the signing
certificate as defined in RFC 5035 [ESSV2].
