Secure Sockets Layer (SSL) is the most widely known protocol that offers privacy and good reliability for client-server communication over the Internet. SSL itself is conceptually quite simple: it negotiates the cryptography algorithms and keys between two sides of a communication, and establishes an encrypted tunnel through which other protocols (like HTTP) can be transported. Optionally, SSL can also authenticate both sides of communication through the use of certificates.

Details configuration is attached. How will have a clear information about how to configure all this.
