SK ID Solutions AS: important changes in SK timestamping service


Dear Partner,

In January 24th, 2024 SK ID Solutions will implement several improvements in timestamping service. The timestamp service certificate and certification chain will be changed.

We urge you to acknowledge the following important dates and to verify that your services are ready to support the changes ahead:
08.11.2023 – new timestamping service endpoints ( and are accessible in production.
24.01.2024 - the switch of current endpoint to new PKI hierarchy (ECC key)

For more details, please see SK website news section about changes:

The transition to new PKI hierarchy and using bigger key lengths adds more security and helps to preserve the long-term integrity of timestamps.
Please let our support know if you encounter problems during testing or if you have any questions: [email protected]
