Improving OpenSSL cert creation

I have a code which uses OpenSSL library to generate a cert with my CA cert, and the cert its basing on is a normal cert I give it.

I need two modifications:

1. Need to copy the "Alternative Subject" extended attribute, from the original cert to the new cert.

2. Need to copy the original expire date from the original cert to the new cert.

Coder should have experience with OpenSSL api because the functions to deal with extended attributes are not documented.
