The primes are used for the Chinese Remainder Theorem, an RSA
speed-up technique.

Hello,
what are the primes in an OpenPGP RSA secret key packet used for?
AFAICT, they are not needed for encryption and/or signing.
Related to that: What will happen if they are omitted, e.g. because an
underlying library can only supply exponent and modulus?
Regards
