SSH, which stands for Secure Shell, is a cryptographic network protocol used for secure remote access and communication between computers.
It provides a secure channel for users to log into remote systems, execute commands, and transfer files securely over unsecured networks.
Key features of SSH include encryption, authentication, remote access, secure file transfer, port forwarding, and tunneling.
For example, running ssh username@remote-server initiates an SSH connection to the specified remote server using the provided username.
SSH is a crucial tool for administrators, developers, and users who need secure access to remote systems and secure data transfer.
