New Timestamping Certificate & CA-Hierarchy

What to do?

If you use Adobe software to obtain and verify the timestamp, the new certificate will be accepted via AATL based on its trustworthiness and no further actions are required.

If you use other software to obtain or to verify timestamps, we recommended that you configure the new CA hierarchy in the software to ensure a smooth transition. For this purpose, we provide you with the links to obtain the new CA certificates:
