I don't believe OpenSSL has any mechanism to directly calculate P and Q; this 
requires an iterative process.  Once you have those, however, calculating the 
rest are simple calculations using the BN library.

Subject: p2q RSA key augmentation

Hi, I have an RSA key { D, E, N } generated by another library.  I can use 
OpenSSL to encrypt & decrypt interoperably, but I would like to extend the key 
with the other factors OpenSSL uses to work faster (factors P, Q, DMP1, DMQ1, 
IQMP).  Is there a library function that computes these other factors?

Thanks,
