Ever watched The Matrix? Well you do remember the green screens with random figures and letters in many of the scenes. Alright, are you able to read the messages on those screens๐Ÿค”? Thought so too.

So the next time you are shopping online, please look out for the 'green padlock' so that you are sure your credit card details are not being stolen or copied over to some other random database which you might not have an idea about.

SSL is a cryptographic protocol designed to provide communications security over a computer network.
