When someone wants to start a conversation they send their public key unencrypted (no need for it to be encrypted) and then you send your public key It will be one more message but the keyboard could have some sort of "profiles" for every persons public key, that you could select (This is just an idea, I have no coding experience)
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.
Ah, I missed the public key part.
That is true, you could do that

Yeah, they're a bit cart ahead of horse on that one.
