Understanding Public & Private Keys: The Key to Secure Online Communication 🔐

Public and private keys are like a secret code system used in online security. Each person has two keys: one is public and shared with everyone, and the other is private and kept secret. The public key is used to scramble information so that only the private key can unscramble it. This way, when someone sends you a message using your public key, only you can read it with your private key. This system is used for keeping online conversations private and for checking that digital messages are real and secure, like in online payments.
