What Is Encryption, and How Does It Work?

If you write something down that is important, private, or sensitive you might worry that someone else is going to read it. If you need to give it to a messenger to take to another person, the risk of the wrong people reading that message increases. Encryption changes the composition of a message or data so that only people who know how to return it to its original form can read it. To anyone else, it’ll appear as gibberish or a meaningless collection of characters and symbols.
