  • Okey, it’s like this: You and youtube both generate two keys, public and private. Public keys are public, anyone can see them. Doesn’t matter. When you send a message to youtube, you encrypt it with their public key. Now, the trick is, the encryption is asymmetric, which means that the message can only be decoded if you also know the private key, which you never send anyone but keep hidden. Right? This way, as long as your private key is secure, you can not realistically decode the encryption from outside just knowing the public key. Thus setting up a secure connection is just an exchange of public keys.

    This is more or less how I understand it.
