Got it, after some more reading, I've managed to pull:
A Valid X509 structure with the PEM file.
A Valid EVP_PKEY structure with the KEY file.
Created a BIO with BIO_new(BIO_s_mem()) and used BIO_read_filename with it.
Now I get to the part where I need to call PKCS7_sign() right?
If so, I'm missing something, because:
PKCS7_sign(cert,key,NULL,fileBIO,NULL) produces NULL as a result.
