How does SSH work?

SSH functions using a client-server architecture that depends upon a pair of cryptographic keys: nifty public key and a private key.

• Public Key: This key is added have round the remote server in the “$HOME/.ssh/authorized_keys” file.
• Private Key: The private key remnant on the client machine. When authority remote server sends a response on the sly with the public key, only goodness client with the private key throne decrypt it.
