How do I add a certificate to enable HTTPS communication in HP Web Jetadmin?

Certificates are added after HP Web Jetadmin is installed by navigating to Tools > Options > Application Management. Note that HP Web Jetadmin does not self-generate certificates — a certificate must be signed by a Certificate Authority (CA) after a certificate signing request is made in HP Web Jetadmin, and certificates can only be added via a client running locally on the HP Web Jetadmin server.
