Well, I haven't examined every crypto library on the planet, it's not to say there isn't something somewhere that implements its keygen as: for i = 0 to 256 dhprime[ i ] = rand(); but of the ones I'm aware of, when you ask for DLP parameters you get something appropriate like Sophie Germain primes or FIPS 186 or equivalent, e.g. Lim-Lee parameter generation. >I don't see a realistic scenario in which sufficiently large ad-hoc server DH >parameters are a problem. +1. Also if mentioning specific published values it'd be good to go with 3526 rather than 7919 due to the non-use of 7919 in implementations (unless there are implementations using the 7919 primes while not implementing 7919 itself).
