Hi,
Nikos Mavrogiannopoulos recently tried building Nettle, using mini-gmp
for all bignum operations. As far as I understand, dnssec support has
(recently?) been added to dnsmasq, using Nettle and GMP. I think GMP is
used here only for *verifying* signatures; no private keys involved and
no
It seems mpz_probably_prime_p considers negated primes to also be prime.
E.g, for n == -29 it returns 2, meaning definitely prime.
Mathematically, I think -29 is usually considered neither prime, nor
composite (its prime factorization is -1 * 29 and the unit factor -1
kind-of doesn't count, since

I agree they are.
On rings I usually take the following definition for primes:
p is prime if and only if p
