When PDF Studio validates digital IDs, it checks that the digital ID was issued by a trusted certificate authority. The trusted certificate authorities can be managed using the preferences available in PDF Studio. By default, PDF Studio will also trust Oracle root certificate authorities, as well as those from your operating system.
To access the trusted certificate preferences do one of the following
My Trusted Certificates allows you to import, view, or delete any additional trusted certificates added to PDF Studio.
Note: When a digital ID is created or imported, its issuing authority is automatically added to the "My Trusted Certificates" list.
Click on the Import button. Then navigate to the certificate you wish to import and click on Open to import the certificate and add the digital ID as a trusted certificate
Note: Only .cer or .crt formats can be imported
Click on the Details button to display the additional details of the selected certificate
Click on the Delete button to delete the selected certificate
Note: This cannot be undone. You will need to reimport the certificate if you wish to trust it again.
The additional certificate settings allow you to enable or disable the PDF Studio or System root certificates. You can also double click on any of the certificates in the list to see their details.
By default, PDF Studio will trust Oracle root certificate authorities. Uncheck the box next to "Trust PDF Studio root Certificate Authorities" if you wish to not trust these authorities
PDF Studio will also trust any system root certificate authorities by default. Uncheck the box next to "Trust System root Certificate Authorities" if you wish to not trust these authorities
