If you want to use only a subset of the trusted certificate authorities in the system or edit an existing 
custom list, you can export the list to a .txt file and edit it to add or remove certificate authorities. After 
you have finished editing the list, import the file back onto the appliance as a custom list.

Navigate to the Network > Certificates page.

Click Edit Settings in the Certificate Authorities section.

Click Export List.

AsyncOS displays the Export Certificate Authority List page.

Select the list you want to export.

Enter a filename for the list. 

Click Export. 

AsyncOS displays a dialog box asking if want to open or save the list as a .txt file.

You can enable a certificate for HTTPS services on an IP interface using either the Network > IP 
Interfaces page in the GUI or the 

interfaceconfig

 command in the CLI. When adding an IP interface 

via the GUI, select a certificate that you want to use for the HTTPS service, check the HTTPS check 
box, and enter the port number.

In following example, the 

interfaceconfig

 command is used to edit the IP interface PublicNet to enable 

HTTPS services on port 443 (the default port). All other defaults for the interface are accepted. (Typing 
Enter at the prompt accepts the default value shown in brackets.)

Note that this example shows using the demonstration certificate that is pre-installed on the appliance. 
You may enable HTTPS services with the demonstration certificate for testing purposes, but it is not 
secure and is not recommended for general use.

You can enable HTTPS services using the System Setup Wizard in the GUI. Refer to “Define the Default 
Router (Gateway), Configure the DNS Settings, and Enabling Secure Web Access” in the “Setup and 
Installation” chapter.
