Downloading an HTTPS certificate signing request
You can download a certification signing request for the current HTTPS security certificate so that you can provide the file to a Certificate Authority to sign. A CA-signed certificate helps prevent man-in-the-middle attacks and provides better security protection than a self-signed certificate.
What you’ll need
You must have the Application Administrator role.
In the left navigation pane, click General > HTTPS Certificate.
Click Download HTTPS Certificate Signing Request.
You can provide the file to a Certificate Authority to sign, and then install the signed certificate.
