Its popularity stems from its simplicity as all that you have to do is download, login with the right credentials, and start accessing remote systems. PuTTY is a popular open-source SSH client that can also be used for SFTP, Telnet, rlogin, and more. Let’s move on to some of the best SSH clients for Windows. So, that’s a brief overview of the client-server model used by SSH. First, the client and the server should agree on common encryption standards for communication, and second, the server verifies the clients’ credentials. The client, on the other hand, uses a TCP handshake to establish a secured symmetric connection and sends its credentials for verification.Īs you can see, there are two steps to establish a secure connection. Once the client sends a message, the server authenticates the client and provides the right shell environment if the verification is successful. The server will listen in on port 22 (you can configure any other port too) for incoming requests from the client. SSH uses a client-server model to facilitate authentication between two systems and encrypts the data that passes between them. Before moving on to the best Windows SSH clients, let’s briefly see how it works. Since it comes with strong encryption to protect communication between systems, more people today turn to SSH to continue their work seamlessly from any place. It also executes commands, supports tunneling, transfers files securely, allows TCP port forwarding, and more.


The Secure Shell protocol, or SSH for short, facilitates remote logging. Logging into office networks from home or other places has become the de facto mode of working in today’s COVID-19 world, and this makes SSH an essential tool in your work-from-home arsenal.
