may vary somewhat. But in general, more primes lead to less generation time
of a key.
-=head1 BUGS
-
-A quirk of the prime generation algorithm is that it cannot generate small
-primes. Therefore the number of bits should not be less that 64. For typical
-private keys this will not matter because for security reasons they will
-be much larger (typically 1024 bits).
