There was a video of someone describing cryptography during a lecture with the example of a secret locked by Alice and sent to Bob. Bob has no way of opening Alice’s lock, so they simply add their lock and send it back to Alice. Then Alice removes her lock and sends the secret back to Bob, who now can remove their own lock and access the secret.

What kind of cryptography is that? Does anyone know what lecture that was?

Public Key cryptography (e.g., PGP, TLS, SSH)

What you described is the goto illustration used for PKI

GP's description looks more like DH Key Exchange.

I'm glad to see that people are willing go even longer distances than me for a practical joke. Unrelated, but this must be the only wikipedia page I know of that contains a joke.

You should also see https://en.wikipedia.org/wiki/Hyper_Text_Coffee_Pot_Control_... as another such Wikipedia page.

That exact image is found in the link I shared, with additional detail :)
