Linux Basics: How To Create and Install SSH Keys on the Shell

Linux Basics: How To Create and Install SSH Keys on the Shell

SSH keys offer a highly secure manner of logging into a server with SSH as against mere dependence on a password. While a password stands the risk of being finally cracked, SSH keys are rather impossible to decipher using brute force. As a matter of fact, generating a key pair offers users two lengthy strings of characters corresponding to a public as well as a private key. Users can, thus, place the public key on any server, and subsequently unlock the same by connecting to it with a client that already possesses the private key. Upon matching up of the two keys, the system unlocks without any irksome dependence on a password. The security may be further smartly firewalled by guarding the private key with a passphrase.
