Hi all,
I need to reconstruct public and private keys for data signing operation from p, q, dmp1, dmq1 and iqmp. When I fill values in as per below then OpenSSL complains about missing d.
RSA* pkey = RSA_new();
pkey->n = NULL;
pkey->e = NULL;
pkey->d = NULL;
pkey->p = BN_bin2bn(secureP.data(), secureP.size(), NULL);
pkey->q = BN_bin2bn(secureQ.data(), secureQ.size(), NULL);
pkey->dmp1 = BN_bin2bn(secureDmp1.data(), secureDmp1.size(), NULL);
pkey->dmq1 = BN_bin2bn(secureDmq1.data(), secureDmq1.size(), NULL);
pkey->iqmp = BN_bin2bn(secureIqmp.data(), secureIqmp.size(), NULL);
I did my homework on Google/Stackoverflow/OpenSSL docu, but I haven't been able to find out any good way to do this, while it is obvious that openssl needs to know this by deafult for its internals.
Would you have any hint on where next with this?
Thank you,
Jan
