How to create a RSA private key from raw data?

[Chris]

I'm having a bit of trouble creating and using RSA keys from raw data.

I have the public exponent(e), public modulus(n), and private modulus(d).

Encryption seems to work (don't know for sure):

      RSA* rsa = RSA_new();
      rsa->e = BN_bin2bn(pubexp, pubexp_len, rsa->e);
      rsa->n = BN_bin2bn(pubmod, pubmod_len, rsa->n);
      result = RSA_public_encrypt(data_len, data, out, rsa, RSA_PKCS1_PADDING);

No errors at least.

Decryption seg faults without e and is incorrect with e:

      RSA* rsa = RSA_new();
      rsa->e = BN_bin2bn(pubexp, pubexp_len, rsa->e);
      rsa->n = BN_bin2bn(pubmod, pubmod_len, rsa->n);
      rsa->d = BN_bin2bn(prvmod, prvmod_len, rsa->d);
      result = RSA_private_decrypt(data_len, data, out, rsa, RSA_PKCS1_PADDING);

Seems strange to seg fault, doesn't it know something is missing/incorrect?  Does RSA_new not initialize the structure to a clean state?  Wouldn't an error be appropriate here?

I assume it's missing some information about the private key.  I couldn't find an "RSA key from raw data" type function though the docs say don't manipulate the internals directly (but give no alternative).  The docs says p, q, dmp1, dmq1, and iqmp are unnecessary, correct?

Thanks for any pointers.
