Cryptographic key types
Okay kiddo, let's talk about cryptographic key types! Have you ever written a secret message to a friend and used a secret code so nobody else could read it? Well, that's similar to what cryptographic keys do, but they are much more complicated!
Cryptographic keys are like codes that computers use to keep information safe and secure. There are two main types of cryptographic keys: symmetric and asymmetric.
Symmetric keys are like a secret password that two people share. Let's say you and your friend each have a secret password. You can use these passwords to write secret messages to each other that nobody else can read. But you have to keep the passwords really, really secret! If someone else finds out the password, they can read all of your secret messages too. That's why symmetric keys are only good for keeping things secure between a few people who know the secret password.
Asymmetric keys are more like special locks that only certain keys can open. Imagine you have a lock with a key that has a special shape. Nobody else can open the lock unless they have a key with the same shape. Asymmetric keys work kind of the same way. There are two keys: a public key and a private key. The public key is like the shape of the lock, and it's okay for anyone to know what it is. The private key is like the special key that fits that lock, and only the person who has the private key can unlock the messages that were sent with the public key.
So that's it, little buddy! Cryptographic keys are like secret codes that computers use to keep information safe and secure. There are two main types: symmetric keys (like secret passwords) and asymmetric keys (like special locks).
