But even in Diffie-Helman the DH parameters will be signed with with server's RSA key. This is how the client can be sure who it is negotiating with. As such the bank analogy for public key crypto is still worthwhile. Also your comment seems like an odd nitpick given the author states in the first paragraph: >"I won't be covering how the protocol itself works in detail here ..." And in the sentence before that they also linked to previous articles they've published on both DH and RSA which go heavily into the details of how each works. It's seems to me like they actually were being quite careful to avoid the very thing you are being critical of even though it was obvious that it wasn't the point in the article.
