SSH stands for Secure Shell, which is a network protocol used for secure remote access to a computer or a network device.
The SSH protocol is used to establish a secure encrypted connection between two devices, typically a client and a server, over an unsecured network such as the internet. This allows users to securely log in to a remote computer or device and execute commands, transfer files, or perform other tasks as if they were physically present at the remote location.
SSH uses public-key cryptography to authenticate the remote device and encrypt the communication between the devices. This means that even if someone intercepts the communication between the client and server, they would not be able to read or modify the data because it is encrypted.
SSH is widely used by system administrators, developers, and other technical users for remote server administration, software development, and other tasks that require secure access to remote resources.
