OpenSSH is free connection tool used for remote login via SSH protocol. It is used by developers and server administrators to access command-line tools and functions on remote servers and computers over the Internet.

OpenSSH encrypts all traffic by default to prevent attackers from listening or intercepting the connection, such as in man-in-the-middle attacks. It supports a wide range of different authentication methods and configuration options. Similar applications include MobaXterm and PuTTY.

What is the difference between SSH and OpenSSH?

SSH stands for Secure Shell and is a tool used to server administration, file transfer and remote communication over the Internet and other networks. It is called secure because the connection and transmission between machines is encryptedtherefore no one can see or follow what is being transmitted.

OpenSSH is easy an open source implementation of SSH. Open source means anyone can inspect the code used to create OpenSSH. This includes the ability to modify the code and create your own versions of it. This is important for security purposes to make sure the code is safe and secure.

Safe and secure remote access over unsecured networks

OpenSSH is completely free industry leading tool to securely connect machines over non-secure connections. It can be used by developers to transfer files between machines, administrators to run tasks on remote servers, and generate/sign cryptographically secure keys, just to name a few of its many uses.

Due to the nature of the use cases and target audience, OpenSSH is not very user friendly. Users tend to be technically competent developers or server administrators, which means that non-technical users will likely find it difficult to use OpenSSH. However, for its target market and specific use cases, OpenSSH is hard to beat.
