+ be used as the identity. Otherwise, the (most specific) Common Name
|
|
|

|
|
|
+ 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.
