Description

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 sign files with Microsoft Authenticode RFC3161 compliant timestamping server.

Please note: TSA certificates are updated at least every 15 months, per industry requirements.
