comment What's the fundamental difference between Diffie-Hellman and RSA?
@B-Con: Actually, it misses the precise point I was trying to make with this post. :) Notice the word "mathematical" in the title -- that was specifically not the real goal of my question/answer here, because I already knew that they're different mathematically (they're different algorithms, after all). :P (See my comment on my answer below.)

@PaĆ­loEbermann: That's definitely a valid answer to the question -- but the issue was that I had a harder time coming up with the question than the answer haha, since wasn't looking for the mathematical difference so much as the nature of their difference. I was looking for someone to explain this^ concept, so when I found it out myself I just wrote a question for it so I could write the answer too. :) If you can think of a better way to phrase the question to match the answer then I'd love to know!

comment Is RSA in a ECB-like-mode safe for bulk encryption?
@fgrieu: Just because it was a handy scheme... I don't really mind that part if it's different though.

+1 thanks for the explanation. Just a question: do you happen to know any ballpark numbers on just how inefficient a scheme like RSA is? (e.g. in KB/s or something, or how many times slower than symmetric encryption, for a typical-sized key.) Just as a rule of thumb -- anything within an order of magnitude is great.

@CodeInChaos: It's just an encryption question -- I'm not worried about a per message overhead (as long as it's fixed), and I haven't worried about authenticity yet (I don't think signing would be a problem here). I'm just asking about the encryption part for now.

I don't understand what you mean by "re-using the private key". Isn't the private key, well, private? How do you 're-use' a private key?

Awesome answer, it fully answers my question! Thanks! :)
