Install OpenSSL Library

Per OpenSSL and IBM sources, OpenSSL is a robust, commercial-grade, and full-featured toolkit for the Transport Layer Security (TLS) and Secure Sockets Layer (SSL) protocols. It is also a general-purpose cryptography library, which provides an encryption transport layer on top of the normal communications layer, allowing it to be intertwined with many network applications and services.
