SSH

SSH (Secure Shell) is a cryptographic network protocol for operating network services securely over an unsecured network. It provides a secure channel for remote login, command execution, file transfers, and tunneling other protocols. SSH is widely used by system administrators and developers to manage servers, network devices, and cloud instances.

Also known as: Secure Shell, SSH Protocol, ssh, OpenSSH, SSH2

Why learn SSH?

Developers should learn SSH for secure remote access to servers, automating deployments, and managing infrastructure in cloud environments. It's essential for tasks like accessing Linux/Unix servers, using Git over SSH, and setting up secure tunnels for database connections or web services. SSH keys provide passwordless authentication, enhancing security and automation in DevOps workflows.
