Hi there.

When I created the DH Keys on my server, I generated 2k and 4k keys. I 
was told the 4k keys shouldn't be used (yet) because of 
incompartibillities and they wouldn't increase the security this much, 
but generate way more problems.

Is this still the state of the art? Shall I stick with 2k or is it 
recommendet to switch to 4K Keys?
