Java: Loading SSL Keystore via a resource

Question

If I have:

System.setProperty(\"javax.net.ssl.keyStore\", \'/etc/certificates/fdms/WS1001237590._.1.ks\');
System.setProperty(\"javax.net.ssl.keyStorePasswor         


        

Answer 1

I had similar problem, I solved creating a function that returns an SSL context using a keystore coming from and input stream.

   protected SSLContext getSslCtx(InputStream is, String password) {
    try {
        // Load keystore
        KeyStore keystore = KeyStore.getInstance("JKS");
        keystore.load(is, password.toCharArray());

        // Load trust manager
        TrustManagerFactory trustMgrFactory = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
        trustMgrFactory.init(keystore);

        // Load key manager
        KeyManagerFactory keyMgrFactory = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
        keyMgrFactory.init(keystore, password.toCharArray());

        // Create SSL context
        SSLContext ctx = SSLContext.getInstance("TLSv1.2");
        ctx.init(keyMgrFactory.getKeyManagers(), trustMgrFactory.getTrustManagers(), null);
        return ctx;
    } catch (Exception e) {
        e.printStackTrace();
    }
    return null;
}

Hope this helps.
