Digital signature and verification

Digital transcripts of grades and student confirmations offered in StudentWeb are digitally signed.

How does a digital signature work?

If someone tries to change the contents of a digitally signed PDF, the digital signature will immediately become invalid. The recipient will then have to verify the digital signature to make sure the content is correct.

How do I check a digital signature?

Very few web browsers show any information about digital signatures. We recommend Adobe Acrobat Reader (free to download) to check if a signature is valid. A ribbon confirming the validity of the signature will be displayed at the top of the document. If you click on the blue ribbon, you will see that Unit – The directorate for ICT and joint services in higher education and research - has signed the document.

Note that it is only possible to verify the signature of the document in its original, digital format. To verify a digital signature, you are required to use a computer, as the signature will not be available on a mobile phone.

Updating trusted certificates

You may experience the error message “There is something wrong with the signature”. The message does not indicate that the signature is invalid, only that your computer is unable to recognise the certificate that was used to sign 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".
