TSP signature

A trust service provider (TSP) is a legal entity providing and preserving digital certificates to create and validate electronic signatures and to authenticate their signatories. The trust service provider has the responsibility to assure the integrity of electronic identification for signatories.

A TSP signature can be defined through the REST API for every recipient per document. It is not possible to define a TSP signature via the user interface, but it is possible to see when a TSP signature is required by a recipient in the signing package wizard and on the Signing packages page.

  • Advanced recipient settings page of the signing package wizard:

    The TSP signature label in the Certificates tab indicates if and what type of TSP signature the recipient is requested to sign a document with.



    Note The available types of a TSP signature are related to the corresponding TSP signature provider used in the system.

    If the label says Not required, no TSP signature is required for the recipient.
