-     field in the Subject field of the certificate MUST be used. Although
-     the use of the Common Name is existing practice, it is deprecated and
-     Certification Authorities are encouraged to use the dNSName instead.
-
-     Matching is performed using the matching rules specified by
-     [RFC2459].  If more than one identity of a given type is present in
-     the certificate (e.g., more than one dNSName name, a match in any one
-     of the set is considered acceptable.) Names may contain the wildcard
-     character * which is considered to match any single domain name
-     component or component fragment. E.g., *.a.com matches foo.a.com but
-     not bar.foo.a.com. f*.com matches foo.com but not bar.com.
-
-     In some cases, the URI is specified as an IP address rather than a
-     hostname. In this case, the iPAddress subjectAltName must be present
-     in the certificate and must exactly match the IP in the URI.
