SSH clients

SSH, or Secure Shell, is a cryptographic network protocol that provides a secure way to access and manage devices over an unsecured network. Developed to replace insecure protocols like Telnet, SSH ensures confidentiality and integrity of data exchanged between a client and a server.

Key features of SSH include encryption, authentication, and secure data communication. When a user initiates an SSH connection to a remote server, the protocol encrypts the communication, preventing unauthorized access to sensitive information. Additionally, SSH uses public-key cryptography for authentication, enhancing security by requiring both a private key on the client side and a corresponding public key stored on the server.

SSH is widely used for remote administration, file transfers, and tunneling, making it an essential tool for system administrators, developers, and anyone needing secure access to networked devices. Its versatility and robust security measures have contributed to its adoption as a standard for secure communication in various computing environments.

Difference between VPN Connection and SSH Connection.

VPN provides network-wide secure communication, while SSH is a protocol for secure remote access and file transfers on a server.
VPN encrypts entire network traffic for privacy, useful in scenarios like browsing. SSH, a protocol, encrypts specific communication, ideal for secure remote administration, file transfers, and tunneling between devices.

Lets check different clients on different systems.

Linux & Mac

Both Linux and Mac have had a great console/terminal with SSH support. I do not recommend to install additional software if you already have a nice


Thought newer windows OS’es include an ssh compatible PowerShell, I do recommend to use one of the many other applications that provide a SSH client. Here a short list of SW that i personally have used in the past.


PuTTY is a widely used open-source terminal emulator and SSH client for Windows. Originally developed by Simon Tatham, it has become a standard tool for secure remote access to Unix-like systems. PuTTY supports various network protocols such as SSH, Telnet, and SCP, providing a straightforward interface for connecting to and managing remote servers.

Key features of PuTTY include its lightweight design, simplicity, and portability.
