RSA generate keys without password

Hi, I'm generating rsa keys using openssl library.

Code:

---

rsa = RSA_generate_key(bits, RSA_F4, NULL, NULL);

---

While generating (and loading key from file), app wants me to enter PEM pass phrase.
Can i generate keys and load them without pass phrase?
Thanks.

any thoughts?

The documentation says that RSA_generate_key is deprecated, no? So use RSA_generate_key_ex. Maybe you're not providing sufficient data in your code itself. I'd be surprised if you couldn't Google a solution, this is not C++ specific.
