How do you know that you're speaking to the real online store, or just a mimic of it? That's where a Digital Certificate comes in, to identify the store as authentic, verified by a trusted Third Party (called the Certificate Authority). If you've spent any time in chat rooms, you know that "Pixiebabe" just might be a middle-aged man in Toledo. Who is your friend and who is the evil hacker? The Internet is a anonymous place where people are not always whom they seem.Two problems present themselves, however, when you don't have face-to-face contact with a trusted friend. If you were to give the key to your friend, he would be able to decode the messages you encode with it and visa versa. Rather than A=L, the key will be very large number used to scramble the text. Modern cryptography uses a very complex algorithm or formula to encode messages using a key. If you someone sent you a message where the "key" is A=L, you'd set the A above the L, and then determine that B=M and C=N, etc. You remember the Decoder Ring you found in a cereal box when you were a kid? It consisted of a wheel with the alphabet on each of two rotating discs. Use it!īut some of you want to know how it works, so here goes. This produces both customer confidence and a very secure communication system. The main message here is that SSL ensures an encrypted communication between the customer's web browser and the merchant's webserver. If you find your eyes glazing over, don't worry.
This is about to get pretty technical so I am simplifying it greatly.
Every modern web browser has built into it a very sophisticated encryption system that allows secure "conversations" with webservers equipped with an SSL secure server (See endnote).
