Enter the password that protects the authority, and then click on Create or renew a CRL.
Remove the CRL | This action allows deleting the CRL for the selected CA or sub-CA. Note This action is not available (grayed-out option) when the CA or sub-CA does not have a CRL.
Set as default | This action makes it possible to define the certification authority used by default on the firewall.

Certificate
