C rsa_sign
You can use RSA_sign to sign the data with SHA256 hash. You can call this RSA_sign (NID_sha256, digest, digest_len, &sign_buffer, sign_len, rsa_key); You have calculate SHA256 hash of the data into digest buffer. rsa_key should be initialized. Since, you have .p12 file, you need to do the following. Create PKCS12 structure from .p12 file.
