In this section of our blog, we will understand how SSH works. Let us understand the technical breakdown of SSH.

Key Exchange and Encryption

Before starting communication, SSH performs a secure key exchange between the client and server. The server provides its public key in response to a connection request made by the client. To establish a secure communication channel, the client generates a session key and sends it back encrypted with the server’s public key. The basis for encrypting the ensuing data transmission is this encrypted session key.


An essential part of the SSH operation is authentication. Users can authenticate themselves using various techniques, including the more secure key-based authentication or the conventional username/password combo. In the latter case, users have two cryptographic keys: a matching public key shared with the server and a private key safely kept on their client computer.

Session Multiplexing

SSH allows multiplexing, which enables many communication channels to run over a single encrypted connection to maximize resource use and boost efficiency. As a result, users can handle multiple tasks at once inside a single SSH session.

Port Forwarding

Port forwarding takes the front stage in extending SSH’s reach. While remote port forwarding enables the server to forward a remote port to a different port on the client, local port forwarding provides secure access to services on a remote server. This fosters secure access to local services much easier.

X11 Forwarding Process

SSH shows off its graphical capabilities by enabling users to run and view local graphical apps on a remote server. This operation makes it possible to communicate with graphical interfaces without issues through a secure SSH connection.
