<p>This Apache Druid module contains a simple implementation of <a href="http://docs.oracle.com/javase/8/docs/api/javax/net/ssl/SSLContext.html">SSLContext</a>
that will be injected to be used with HttpClient that Druid processes use internally to communicate with each other. To learn more about
Java's SSL support, please refer to <a href="http://docs.oracle.com/javase/8/docs/technotes/guides/security/jsse/JSSERefGuide.html">this</a> guide.</p>
