Hi. I've generated a 2047-bit "strong" prime number that I would like to
use with Diffie-Hellman key exchange. I assert that not only is this number
'p' prime, but so is (p-1)/2.
I've used the mpz_probab_prime() function in the Gnu Math Package (GMP) version
1.3.2 to test this number. This function uses the Miller-Rabin primality test.
However, to increase my confidence that this number really is a strong prime,
I'd like to ask others to confirm it with other tests. Here's the number in hex:
The generator, g, for this prime is 2.
