Asymmetric Key Encryption(Public/Private)

Think of a box that we put things inside of:(put simply)

• Private key: can open the box
• Public key: can lock the box

Caveats:

Public keys contain a unique signature, which can be used to sign a message. Even though everyone can open the message they also know who locked the box.

Imagine then, lock the box with private key(secure) and sign it with the public key(authorized).
