HttpClient provides full support for HTTP over Secure Sockets Layer (SSL) or IETF Transport Layer Security (TLS) protocols by leveraging the Java Secure Socket Extension (JSSE). Security aside, this technique is commonly done in earlier versions of HttpClient; but the configuration API (SSL configuration especially) API have changed radically in 4.4.
