Books on cryptography
A book on cryptography is like a secret code book that teaches people how to make messages that nobody else can read unless they have the right key to decode it. It's like playing a game where you and your friend are the only ones who know the rules, so nobody else could understand your secret messages.
Imagine that you draw a picture of your favorite toy and you want to send it to your friend who lives in another city. But you don't want anyone else to see it, so you put the drawing in an envelope and seal it tightly. However, someone might still open the envelope and see what's inside, especially if they are very good at guessing.
In cryptography, you could use a special code to hide your drawing in a way that only your friend can decode it. You could use a code book that you both have, which has a list of secret words and their corresponding meanings. For example, you could agree that the word "apple" means "favorite toy" and the word "banana" means "secret message."
So when you draw your favorite toy, you would write "apple" instead of "favorite toy" and "banana" instead of "secret message". Then you put the message in the envelope and mail it to your friend. When your friend receives the message, they will look up the code words in the code book and decode the message.
A book on cryptography teaches you all about different types of codes, how they work, and how to create them. It shows you how to make your messages completely unreadable to anyone who doesn't know the code, and how to keep your messages safe and secure. It's like having your very own secret language that only you and your friends can understand!
