Encryption is like putting your message inside a locked box before sending it. When you want to keep something private, like a secret note, you use encryption to turn it into a code that only the intended recipient can understand. It's a bit like speaking a secret language that only you and your friend know. In the digital world, encryption takes your private information and scrambles it into a format that looks like gibberish to anyone who tries to peek at it without the right 'key' to unlock it. This way, even if someone intercepts your message, they can't read it unless they have the secret key to decode it. Encryption is crucial for keeping sensitive information, like passwords or credit card numbers, safe and secure online.
