To clear this up:
I am well aware how DH works, and what the mathematical properties
of p and g are and have to be.
My point was that some commercial vendors (Check Point and others)
claim, that if two partners
I'm not certain I understand your questions, but here are some answers (I
think).
In the DH protocol you have what we call public parameters, p and g.
p is a large prime integer, which defines a group Z*p, g is a generator
which
defines a subgroup in Z*p.
You can use fix values for p an g.
Now, par
