What's the right way to make a RSA public key from two BIGNUM n and e?

[Zihan, Sheldon Liu]

What's the right way to make a RSA public key from two BIGNUM n (modulus)
and e (public exponent)?

RSA* pubKeyRSA = RSA_new();
pubKeyRSA->n = n;
pubKeyRSA->e = e;

This way seems working. But I didn't find it is documented anywhere.
Is there a direct API taking n and e, and returns a RSA*? Thanks.

I don't think there is an official API. I use your method and it works
across many platforms.

An example is documented in the openSSL wiki: http://wiki.openssl.org/index.php/Manual:D2i_RSAPublicKey(3)
