# What is the SSH protocol?

## The SSH protocol

SSH stands for _Secure Shell Protocol_. It is a cryptonet protocol that allows services to be performed securely even on an unsecured network. It is generally used to execute online commands and establish remote connections.

SSH applications use a client-server architecture. This architecture directly links the client’s browser to the site’s server.

SSH does more than provide a secure connection between computers, both local and remote. It also manages virtualization platforms, routers, operating systems, server hardware and even file transfer applications. 

The SSH protocol connects to servers, performs downloads and makes changes using dedicated tools or directly from the terminal.

SSH keys automate direct access to servers. They are often used in scripts, backup systems and configuration management tools.
