Requesting a Certificate Authority-signed certificate
A Certificate Authority (CA)-signed certificate provides more security than a self-signed certificate and is appropriate for HTTPS and SMTP/TLS communication. Before you proceed, determine the CA from which you want to purchase your certificate. Some possible CAs to use are listed on the Certificate Authority tab in the Control Center. However, other CAs are also supported.
For the common name, use the domain name or the fully qualified domain name of the computer where the certificate will be installed. Some CAs may not support certificates that are created using an IP address instead of a domain name for the common name. Check with your CAs.
See Viewing existing CA certificates.
See About certificates.
Each CA has its own set of procedures to request certificates and issue certificates. Consult your CA for details and follow the instructions that are appropriate for your installation.
See Adding a CA certificate.
