Marek, Thanks a lot. I think I was improperly using memory. After I cleaned up some unused RSA_new, EVP_PKEY_new etc.., it started working. Your test program helped me learn openssl error logging.
One more question before I move to new agenda. Is siglen RSA_size? Should rsa_pv and rsa_pb the same size? Thanks again.

RSA_sign/verify does not work. What did I miss? This looks good, maybe there are some other problems. I've attached quick test based on this code - maybe this will help.
