DHE: warn against most common 1024 bits primes

Hello,

related to https://weakdh.org/ is the top 10 list of the most common DHE 1024 bits prime public?

Is it possible to remotely detect which prime is used (apparently zmap does it) and turn the current "DH 1024 bits (p: 128, g: 1, Ys: 128)   FS    WEAK" into something more precise (and eventually flagged as insecure) especially if the prime belongs to the top 3 apparently broken by the NSA?

 

Cheers

Valérie
