Records are timestamped using industry-standard RFC 3161. The timestamping process creates a Timestamp Response file (.tsr) which is marched to a corresponding record source text file (.txt). By using the public keys (cacert.pem and tsacert.pem) included in the export folder, you can independently verify each record.
We recommend using OpenSSL which is available across Windows, OSX, and Linux, and is often preinstalled. Timestamp verification is available in OpenSSL versions 0.9.9 and greater.
Verification can be performed using the OpenSSL command below from a command line prompt. Simply replace RECORD_TO_VERIFY with the ID of the record you are attempting to verify, and make sure cacert.pem and tascert.pem are pointing to the keys included in the export folder.
The correct response is Verification: OK when the record passes the verification test.
Questions about this process can be directed to support.
