I'm asking about the sslabs rating for SSL Server Test: librelamp.com (Powered by Qualys SSL Labs)
The key exchange part is not at 100% and I'm curious as to what dinged it.
Not that 100% on everything is important, but if it is something that can be improved I would like to.
One thing I don't do is HPKP - I do DANE for key pinning, philosophical disagreement with HPKP but I don't think that's a ding on key exchange.
Anyway just curious if anyone knows what the ding is.
