Secure Shell (SSH)

Secure Shell (SSH) (1995) is a cryptographic network protocol for connecting to ssh network services providing encrypted communication and authentication. Most popular implementation is open source OpenSSH.

OpenSSH includes the following binaries:

• ssh, ssh client to connect using Secure Shell protocol
• scp, a replacement for obsoleted rcp
• sftp, a replacement for not encrypted ftp
• sshd, the SSH server daemon
• ssh-keygen, a tool to inspect and generate the RSA, DSA and Elliptic Curve keys that are used for user and host authentication
• ssh-agent
• ssh-add
• ssh-keyscan, to scan a list of hosts and collects their public keys
• ssh-copy-id, to copy local keys to remote machine.

Ssh clients:

• PuTTY
• ssh (OpenSSH)
