Cryptography
Cryptography is the art of keeping messages secret by turning them into codes that only intended people can read. ๐
๊ฐ๋จ ์๊ฐ
Just like how you might use a secret language with your best friend, cryptography is about protecting information from others. ๐คซ It's used everywhere in our digital world, from sending text messages to making online purchases. Think of it as putting your message in a super-secure locked box where only the person with the right key can open it.

Making Messages Secret ๐
It's like having a special decoder ring from a cereal box, but much more complex. When you type a message, cryptography scrambles it into something that looks like gibberish. Only someone with the right 'decoder ring' (called a key) can unscramble it.
Keys and Locks ๐
Just like your house has locks and keys, cryptography uses digital keys. Sometimes you use the same key to lock and unlock (like your house key), and sometimes you use different keys (like a public key to send messages and a private key to read them).
Protecting Information ๐ก๏ธ
It's like putting your diary in a safe. When you shop online, cryptography protects your credit card number. When you use social media, it keeps your password secure. It's working behind the scenes to keep your digital life private.

- When you see the little padlock ๐ symbol in your web browser while shopping online, that's cryptography making sure your credit card information stays safe.
- Writing a message like 'HELLO' as 'IFMMP' by shifting each letter forward by one is a simple form of cryptography - just like secret codes kids use in games.
- WhatsApp's 'end-to-end encryption' is like putting your message in a magical envelope that can only be opened by your friend's phone - even WhatsApp can't read it! ๐ฑ
