/* The IETF defines standard primes as "Modular Exponential (MODP) Groups" for
use in IKE in RFC 2409 and 3526, and then some more, "for Use with IETF
Standards" in RFC 5114.  These have been thoroughly reviewed as meeting
certain eligibility criteria, which is more than can be said for primes
generated quickly on no particular criteria.

Any prime used in TLS is disclosed publicly, and if the security of your
session depends upon the prime being secret, then one of three situations
holds:
 (1) the prime is too small
 (2) the prime is flawed, use one of these instead
 (3) you know of fundamental cryptanalytic breaks not currently publicly known
     to the cryptographic community.
