-
- 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.
