java.security.NoSuchAlgorithmException: X509 KeyManagerFactory not available
<p>I want to create SSL connection. I created keystore. and trying to use x509.</p>

<pre><code> final KeyManagerFactory kmf = KeyManagerFactory.getInstance("X509");
</code></pre>

<p>but I am getting below exception on console after running.  </p>

And also with "SunX509" i am getting                                              java.lang.IllegalArgumentException: Cannot support TLS_RSA_WITH_AES_256_CBC_SHA with currently installed providers problem with some ciphers. please help
