Managing Trusted Certificates
When Xodo 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 Xodo PDF Studio. By default, Xodo PDF Studio will also trust Oracle root certificate authorities, as well as those from your operating system.
Accessing the Trusted Certificate Settings
To access the trusted certificate preferences do one of the following
- Go to Secure Tab >
Trusted Certificates on the toolbar - Go to File > Preferences then select Trusted Certificates from the panel on the left
Trusted Certificate Options
The additional certificate settings allow you to enable or disable the Xodo PDF Studio or System root certificates. You can also double click on any of the certificates in the list to see their details.
System Certificates
