Hi, I have a privatekey file written using the call PEM_write_bio_RSAPrivateKey (...) The file write operation has been successful. However, when i am trying to read it via calls PEM_read_bio_PrivateKey(..) or PEM_read_bio_RSAPrivateKey(..) , it is always returning NULL. There is no encryption also done . It i unencrypted private key. Can someone help me to understand what might be wrong. And the same is while reading public key also Actually write operations are successful but read operations are not successful, what I am might be missing?
