Java CertificateException “No subject alternative names matching IP address … found”

certificateipjavassl

I'm trying to implement a selfsigned certificate into my webserver, and it's working already with firefox and chrome (both from the server itself and from a remote machine)… but I can't get it to work with java. I've already created a keystore file that contains my certificate, but every time I try to connect to the Server it gives me a SSLHandshakeException: javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: No subject alternative names matching IP address 192.168.178.71 found

The code I'm using for this test is:

public static void main(String[] args) {
         System.setProperty("javax.net.ssl.keyStore",                    HTTPStest.class.getResource("keystore.jks").getFile());
            System.setProperty("javax.net.ssl.keyStorePassword",           "lead"); 
        URL url;
            InputStream is = null;
            BufferedReader br;
            String line;

            try {
                url = new URL("https://192.168.178.71/");
                is = url.openStream();  // throws an IOException
                br = new BufferedReader(new InputStreamReader(is));

                while ((line = br.readLine()) != null) {
                    System.out.println(line);
                }
            } catch (MalformedURLException mue) {
                 mue.printStackTrace();
            } catch (IOException ioe) {
                 ioe.printStackTrace();
            } finally {
                try {
                    if (is != null) is.close();
                } catch (IOException ioe) {
                    // nothing to see here
                }
            }

    }

And when checking my certificate with openssl it gives me this:

Can anyone help me solve this problem? I know that I could just go for a hostname, but I would like to have it work this way too

Best Answer

Your certificate should include that ip value as a subject alternative name value (of type IPAddress : key=7).
