The corresponding private key pair will be saved on your local PC.The public key will be added to your node.Generating a key pair provides you with two long string of characters: a public and a private key.
If the key-pair matches then a shell session is spawned or the requested command is executed. When a client attempts to authenticate using SSH keys, the server can test the client on whether they are in possession of the private key. The public key is uploaded onto the remote server that you want to be able to log into with SSH. The private key is retained by the client on his local machine and should be kept absolutely secret. Any compromise of the private key will allow the attacker to log into servers that are configured with the associated public key without additional authentication. As an additional precaution, the key can be encrypted on disk with a passphrase. Each key pair consists of a public key and a private key. SSH key pairs are two cryptographically secure keys that can be used to authenticate a client to an SSH server. SSH keys prove to be a reliable and secure alternative. Modern processing power combined with automated scripts make brute forcing a password-protected account very possible since passwords generally are not complex. The most basic of these is a password-based authentication, which is easy to use but isn’t the most secure. Why is a password-based authentication vulnerable?Ī server can authenticate & grant access to the users with different access methods. Cracking the security system of a node depending on SSH keys is nearly impossible since it secures your node in a more sophisticated way by the use of encoded keys.

Setting up SSH based security to access your server is a much more effective way than the use of a manual root password.
