Hey, just to be sure what I understand: "It sounds like the 'ephemeral keys' you mention could be the circuit-level keys, that is, the symmetric keys negotiated by the circuit handshake and used for the lifetime of that circuit."
Is it the 128-bit AES key? They are talking about in point 4.1 of the article?
