An RFC3161 timestamp server provides an essential function in protecting data records for the long-term. It provides proof that the data existed at a particular moment in time and that it has not changed, even by a single binary bit, since it was notarized and time-stamped.
DigiCert offers a RFC 3161 timestamp server; therefore, it is now possible to signed files with Microsoft Authenticode RFC3161 compliant timestamping server.
The RFC 3161 timestamping URL is http:/timestamp.digicert.com
