Digital Signatures at Uppsala University

If Adobe Acrobat notifies you that the signature is invalid:
At present, some digital signatures cannot be validated without some adjustment in standard PDF-readers from Adobe. This is because Adobe has not listed Uppsala University's certificate issuer Sectigo in its catalogue of trusted certificates. Therefore, programs such as Adobe Acrobat Reader may display a message when opening a document stating that the signature is not verified and that the identity behind the signature is unknown.
The notice does not affect the validity of the PDF-document within the university and documents that are signed digitally as specified in the instructions below are accepted for all activities within Uppsala University.
