/**
 * <p>
 * EasySSLProtocolSocketFactory can be used to creats SSL {@link Socket}s 
 * that accept self-signed certificates. 
 * </p>
 * <p>
 * This socket factory SHOULD NOT be used for productive systems 
 * due to security reasons, unless it is a concious decision and 
 * you are perfectly aware of security implications of accepting 
 * self-signed certificates
 * </p>
 *
 * <p>
 * Example of using custom protocol socket factory for a specific host:
 *     <pre>
 *     Protocol easyhttps = new Protocol("https", new EasySSLProtocolSocketFactory(), 443);
 *
 *     HttpClient client = new HttpClient();
 *     client.getHostConfiguration().setHost("localhost", 443, easyhttps);
 *     // use relative url only
 *     GetMethod httpget = new GetMethod("/");
 *     client.executeMethod(httpget);
 *     </pre>
 * </p>
 * <p>
 * Example of using custom protocol socket factory per default instead of the standard one:
 *     <pre>
 *     Protocol easyhttps = new Protocol("https", new EasySSLProtocolSocketFactory(), 443);
 *     Protocol.registerProtocol("https", easyhttps);
 *
 *     HttpClient client = new HttpClient();
 *     GetMethod httpget = new GetMethod("https://localhost/");
 *     client.executeMethod(httpget);
 *     </pre>
 * </p>

 * The component is provided as a reference material, which may be inappropriate
 * for use without additional customization.
