SSH (22)

Secure Shell (SSH) is a cryptographic network protocol for operating network services securely over an unsecured network.

Typical applications include remote command-line, login, and remote command execution, but any network service can be secured with SSH.

On Linux systems, SSH keys are usually stored in ~/.ssh/.

The private key is stored in ~/.ssh/id_rsa and the public key in ~/.ssh/id_rsa.pub.

Commands​

ssh-keygen -t rsa -b 4096 -C "<email>"

Connect to a remote host​

ssh <user>@<host>
