Certificates required for verifying digital signatures

In order to verify files that are digitally signed with an ID-card or a mobile-ID (or another digital document) and/or digitally stamped, all of the root certificates, certifiers and OCSP-responder certificates used to date, incl. expired certificates, must be configured in the information system.

Over the years, different certifier and OCSP-responder combinations have been used, an overview of which is presented in the tables below.

All of the certificates can be downloaded from the SK ID Solutions website:
