How do I check a digital signature?
Few browsers display information about digital signatures. We therefore recommend that you use Adobe Acrobat Reader (can be downloaded for free) to check if a signature is intact. A "ribbon" on a blue background with information about the validity of the signing will then appear at the top of the screen. If you press the signature panel in the blue "ribbon", you will get more information about the signature and the certificate.
Our documents will be signed by one of the following:
- Ceres - National Center for Joint Systems and Research and Study Services
- Unit – Norwegian Directorate for ICT and Joint Services in Higher Education & Research
- Sikt - Norwegian Agency for Joint Services in Education and Research
Different editions of the digital signature
The digital signature and associated text and seal have changed somewhat along the way, and may be different on different documents and websites. This applies to both text and the associated seal (rosette / logo).
The period from June 15 th 2022
Sikt - Norwegian Agency for Joint Services in Education and Research is the issuer of the digital certificate and the seal is a Sikt logo. The signature now typically looks like this:
The period from February 26th 2020 to May 15th 2022
Unit – Norwegian Directorate for ICT and Joint Services in Higher Education & Research was the issuer of the digital certificate and the seal was a gold rosette with a U in the middle.
The period before February 26th 2020
CERES - The National Center for Common Systems and Services was the issuer of the digital certificate and the seal was a gold rosette with a C in the middle.
Documents from the Diploma Registry
Note that for digitally signed PDFs that have been ordered and produced in the Diploma Registry, the seal is a gold rosette with a V in the middle.
Grade transcripts and student confirmations from Studentweb
Grade transcripts and student confirmations still have a signature from the Unit – Norwegian Directorate for ICT and Joint Services in Higher Education & Research and thus also a seal in the form of a gold rosette with a U in the middle. Transition to signature from Sikt will take place during the autumn 22.
Problems verifying the signature?
It is not possible to verify a digitally signed PDF on a mobile phone. We therefore recommend that you verify the document on a computer.
Some users experience the message "There is at least one problem with the signature" when trying to verify the digitally signed PDF. At the same time, a dialog box will appear with questions about downloading / installing trusted certificates. You must press OK on this if you want your computer to verify the signature. If you can check for automatic installation in the future, we recommend that you do so to avoid getting this message again.
This message does not indicate that the signature is invalid, only that your computer is unable to recognise the certificate that was used when signing the document. In such cases the certificate must be added to a whitelist on your computer. To update the whitelist, follow our user guide “Update the list of trusted certificates on your computer".
