I see. Thanks for the explanation. So a PRF is similar to a Hash, in that it takes input values and produces a "representative" sample of those values, except that a PRF can produce an arbitrary length result. If two people have the same starting data, and use the same hash function within the PRF, and are trying to acquire the same length data, they will always end up with the same final value. (correct me if I'm wrong).

comment TLS/SSL's usage of Non-Ephemeral DH vs DHE
Brilliant answer, thanks! One quick question. When you answered the first question, you said "...The group might be explicitly specified (as is common in the case of DH) or referenced by an identifier (as is common in the case of ECDH)." For DH, do you mean that the Public Certificate will also include (along with X), the DH Group#, aka, 1, 2, or 5? If so, what did you mean by an "identifier" which is the case of ECDH"
