A private key is a unique individual password to your individual crypto wallet address. A public key then adds an extra layer of security and ensures that your wallet can’t be hacked. Here is a quick example of what the keys look like:
Private key: 03bf350d2821375158a608b51e3e898e507fe47f2d2e8c774de4a9a7edecf74eda
Public key: 99b1ebcfc11a13df5161aba8160460fe1601d541
These addresses look completely different to the eye, but the software technology knows that the two keys are specifically linked to each other. That proves that you’re the owner of the coins and allows you to transfer funds whenever you want.
