    Okay, but how do you then make sure that key isn’t intercepted? Anyone who has the key can read your messages

      They are talking about asymmetric encryption which has a keypair, private key (kept secret only by the owner) and a public key that is used by everyone that would send them a message. You can’t decrypt the message with the public key when it is encrypted using the public key, you must use the private key to decrypt it.
