About public key.
What about public key? You wrote the words "About public key" and then you didn't actually write ANYTHING about public keys at all.
I read good article https://en.bitcoin.it/wiki/Technical_background_of_version_1_Bitcoin_addresses
That is about UNCOMPRESSED VERSION 1 addresses (also known as uncompressed P2PKH addresses).
As I said, there are many types of addresses.
That link describes 2 ways of representing a private key (WIF and Mini-key) as well as an additional way of storing and generating keys (HD).
This is impossible.
What is impossible?
