2.1 already does something similar.  Because the keys are generated by
the gpg-agent daemon the prime cache in Libgcrypt is actually used:
Libgcrypt first generates a pool of smaller primes and then tries
permutations of them to find a suitable strong prime.  The unused small
pool primes are then put into a cache and used for the next prime

Anyway, with the move from RSA to ECC, we don't need the secret primes



Die Gedanken sind frei.  Ausnahmen regelt ein Bundesgesetz.
