SSH

SSH (Secure Shell) is a cryptographic network protocol for securely operating network services over an unsecured network, primarily used for remote login and command execution on servers. It provides strong encryption, authentication, and data integrity to protect against eavesdropping and tampering, commonly implemented through tools like OpenSSH.

Also known as: Secure Shell, sshd, OpenSSH, ssh-client, ssh-server

Why learn SSH?

Developers should learn SSH for securely managing remote servers, automating deployments, and accessing cloud infrastructure, as it is essential for DevOps, system administration, and backend development. It is critical in scenarios requiring secure file transfers (via SCP or SFTP), tunneling, and remote debugging in production environments.
