Class StrictHostnameVerifier

java.lang.Object
  extended by org.apache.http.conn.ssl.AbstractVerifier
      extended by org.apache.http.conn.ssl.StrictHostnameVerifier
All Implemented Interfaces:
HostnameVerifier, X509HostnameVerifier

public class StrictHostnameVerifier
extends AbstractVerifier

The Strict HostnameVerifier works the same way as Sun Java 1.4, Sun Java 5, Sun Java 6-rc. It's also pretty close to IE6. This implementation appears to be compliant with RFC 2818 for dealing with wildcards.

The hostname must match either the first CN, or any of the subject-alts. A wildcard can occur in the CN, and in any of the subject-alts. The one divergence from IE6 is how we only check the first CN. IE6 allows a match against any of the CNs present. We decided to follow in Sun Java 1.4's footsteps and only check the first CN. (If you need to check all the CN's, feel free to write your own implementation!).

A wildcard such as "*.foo.com" matches only subdomains in the same level, for example "a.foo.com". It does not match deeper subdomains such as "a.b.foo.com".

StrictHostnameVerifier

public StrictHostnameVerifier()
Method Detail

verify

public final void verify(String host,
                         String[] cns,
                         String[] subjectAlts)
                  throws SSLException
Description copied from interface: X509HostnameVerifier
Checks to see if the supplied hostname matches any of the supplied CNs or "DNS" Subject-Alts. Most implementations only look at the first CN, and ignore any additional CNs. Most implementations do look at all of the "DNS" Subject-Alts. The CNs or Subject-Alts may contain wildcards according to RFC 2818.

Parameters:
host - The hostname to verify.
cns - CN fields, in order, as extracted from the X.509 certificate.
subjectAlts - Subject-Alt fields of type 2 ("DNS"), as extracted from the X.509 certificate.
Throws:
SSLException - If verification failed.

toString

public final String toString()
Description copied from class: Object
Returns a string containing a concise, human-readable description of the receiver.

Overrides:
toString in class Object
Returns:
String a printable representation for the receiver.
