Method Details

getCNs

public static String[] getCNs(X509Certificate cert)

getDNSSubjectAlts

public static String[] getDNSSubjectAlts(X509Certificate cert)

Extracts the array of SubjectAlt DNS names from an X509Certificate. Returns null if there aren't any.

Note: Java doesn't appear able to extract international characters from the SubjectAlts. It can only extract international characters from the CN field.

(Or maybe the version of OpenSSL I'm using to test isn't storing the international characters correctly in the SubjectAlts?).

Parameters:

cert - X509Certificate

Returns:

Array of SubjectALT DNS names stored in the certificate.

verify

public boolean verify(String host,
 SSLSession session)

The javax.net.ssl.HostnameVerifier contract.

Specified by:

verify in interface HostnameChecker

Specified by:

verify in interface HostnameVerifier

Parameters:

host - 'hostname' we used to create our socket

session - SSLSession with the remote server

Returns:

true if the host matched the one in the certificate.
