Ruby implements github third-party authentication

GitHub uses a two-key mechanism during user authentication. In the two-key encryption mechanism, only valid users have private keys, as long as GitHub can prove that the client that submitted the request has the private key when receiving the request, it can be confirmed that the operation was initiated by a legal user. Let's use ruby to simulate it.

The code is very simple. There is no nonsense here.
