I do think we should mention DHE-2048. It's the classic, well-understood concept. I take a very conservative POV here, but ECC is younger and less tested. Add to that the NSA speculations. You're right about the Apaches, but Windows users, I think, should not be too much of a problem once Microsoft decides to enable DHE-2048 and push it out with their update mechanism. > And if you're worried about NIST curves, there are people pushing > brainpool and other curves on the TLS list. Brainpool and/or djb's curves will take some time for adaption, too, especially for secure implementations. Another reason to mention the classic DHE alternative.
