SSH only verifies that the same person offering the public key also owns the matching private key. While authentication is based on the private key, the key is never transferred through the network during authentication. In this scenario, the public key is placed on all computers that must allow access to the owner of the matching private key, which the owner keeps private.

When the public-private key pair is generated by the user manually, the authentication is essentially performed when the key pair is created, and a session may then be opened automatically without a password prompt. In the simplest manner, both ends of a communication channel use automatically generated public-private key pairs to encrypt a network connection, and then use a password to authenticate the user.
SSH may be used in several methodologies. SSH uses public-key cryptography to authenticate the remote computer and allow it to authenticate the user, if necessary.

The most commonly implemented software stack is OpenSSH, released in 1999 as open-source software by the OpenBSD developers. The protocol specification distinguishes two major versions, referred to as SSH-1 and SSH-2. Subsequent development of the protocol suite proceeded in several developer groups, producing several variants of implementation. SSH was first designed in 1995 by Finnish computer scientist Tatu Ylönen. SSH was designed on Unix-like operating systems, as a replacement for Telnet and for unsecured remote Unix shell protocols, such as the Berkeley Remote Shell (rsh) and the related rlogin and rexec protocols, which all use insecure, plaintext transmission of authentication tokens. SSH operates as a layered protocol suite comprising three principal hierarchical components: the transport layer provides server authentication, confidentiality, and integrity the user authentication protocol validates the user to the server and the connection protocol multiplexes the encrypted tunnel into multiple logical communication channels. SSH applications are based on a client–server architecture, connecting an SSH client instance with an SSH server. Its most notable applications are remote login and command-line execution. Note: Make sure your Raspberry Pi and the computer you are using to SSH into your Raspberry Pi are connected to the same network.The Secure Shell Protocol ( SSH) is a cryptographic network protocol for operating network services securely over an unsecured network. Here, use the IP address you found out in the previous step.
On Windows, you can use a SSH client like Putty. Open a terminal (on Mac and Linux) on the computer from which you want to SSH into your Pi and type the command below. In the past, a malware infected thousands of Raspberry Pi devices that were using the default username and password. Ideally you must change the default password. If you have changed the default password then use the new password instead of the above. You’ll also need the username and the password for the Raspberry Pi. Now that you have enabled SSH and found out your IP address you can go ahead and SSH into your Raspberry Pi from any other computer. You can also find out the IP address by other means like checking the network devices list on your router/modem. If you use WiFi check under the entry named ‘ wlan0‘. The first entry( eth0) shows IP address as 192.168.2.105 which is valid.I have used Ethernet to connect my Raspberry Pi to the network, hence it is under eth0. This command shows all the list of active network adapters and their configuration.
