A private key is essentially a randomly generated number. The library is written in a way that it tries to upgrade pubkey only ecdsa objects to private key enabled ecdsa objects upon successful recovery. Private Key Format Bitcoin. And 256 bits is exactly 32 bytes. A public key can be calculated from a private key but not vice versa.
