struct rsa_st in rsa.h says that n, e, d, p, q, etc. are BIGNUM. bn.h tells you about BN_bin2bn. So you can use prepare your hex strings appropriately, use BN_bin2bn to convert them to BIGNUMs, then populate your struct rsa_st. You'll want to check out how RSA_generate_key does it to make sure you maintain rsa_st's internal consistency.
