/**
 * Low-level SSL extension point.
 *
 * SSL is separated into two interfaces to avoid exposing Netty classes in our public API:
 *
 * 

 *   "normal" (JDK-based) SSL is part of the public API, and can be configured via an instance
 *       of {@link com.datastax.oss.driver.api.core.ssl.SslEngineFactory} defined in the driver
 *       configuration.
 *   
this interface deals with Netty handlers directly. It can be used for more advanced cases,
 *       like using Netty's native OpenSSL integration instead of the JDK. This is considered expert
 *       level, and therefore part of our internal API.
 * 
 *
 * @see DefaultDriverContext#buildSslHandlerFactory()
