Hi, everyone,
I am trying to generate two different DH modulus(actually safe
primes), and I know the following code would give me a DH modulus,:
DH dh1;
NonblockingRng rng1;
dh1.AccessGroupParameters().GenerateRandomWithKeySize(rng1, 512);
p = dh1.GetGroupParameters().GetModulus();
But I don't know how to generate another different DH modulus. I've
tried creating a different DH objects, use two different randompool
rngs with different seeds, but I always get two same DH modulus.
Could anyone give me some help? Thank a lot.
Alex
btw, I've tried the following methods:
/////////////////////////////////////////////////////////////////////
DH dh1,dh2;
NonblockingRng rng1;
dh1.AccessGroupParameters().GenerateRandomWithKeySize(rng1, 512);
p = dh1.GetGroupParameters().GetModulus();
NonblockingRng rng2;
dh2.AccessGroupParameters().GenerateRandomWithKeySize(rng2, 512);
q = dh2.GetGroupParameters().GetModulus();
printf("p = %ld\n",p);
printf("q = %ld\n",q);
////////////////////////////////////////////////////////////////////////
const unsigned int SEEDSIZE = 16;
byte pcbSeed1[SEEDSIZE] = {0,0,0,0, 0,0,0,0, 0,0,0,0,
0,0,0,0};
byte pcbSeed2[SEEDSIZE] = {1,0,0,0, 0,0,0,0, 0,0,1,0,
0,0,0,1};
CryptoPP::RandomPool rng1, rng2; //two rngs with seed size of
16
rng1.Put(pcbSeed1,SEEDSIZE);
rng2.Put(pcbSeed2,SEEDSIZE);
