I am not quite sure I understand your question(s). For example: "how can i use this to do secure exchange"
When you're using SSL, your connection / exchange *is* already secure. That's the whole idea about SSL; the browser and the server set up a secure connection when you specify that the connection should use SSL.
I suggest you pick up a book or do some Googling for this. This is a too broad topic, and too broad questions to answer in a forum.
Cheers,
