TLS uses X.509 certificates. All servers are required to have valid

certificates, whereas client certificates are optional. We will only

be discussing server certificates.

The DN of a server certificate must use the CN attribute to name the

server, and the CN must carry the server's fully qualified domain name

(FQDN). Additional alias names and wildcards may be present in the

<option>subjectAltName</option> certificate extension. More details on
