List the contents of /.ssh directory. Check the ssh client version. YouвЂ™ll be asked to enter a file name for the key pair.SSH set up for git on Mac OS. If you donвЂ™t see any keys in your SSH directory, then you can run the ssh-keygen command to generate one. The default SSH public and private key names on a MacBook are idrsa.pub and idrsa. Pub extension and private keys have no extension.

Generating a key pair provides you with two long string of characters: a public and a private key. A key pair will be generated on your local PC. If theВ key-pair matchesВ then a shell session is spawned or the requested command is executed. Each key pair consists of a public key and a private key.The private key is retained by the client on his local machine and should be kept absolutely secret.В 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.В As an additional precaution, the key can be encrypted on disk with a passphrase.The public key is uploaded onto the remote server that you want to be able to log into with SSH.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. SSH keys prove to be a reliable and secure alternative.SSH key pairs are two cryptographically secure keys that can be used to authenticate a client to an SSH server. It stores your passphrase in macOS keychain and add SSH-key in SSH-agent, and persist until we restart the system.Modern processing power combined with automated scripts make brute forcing a password-protected account very possible since passwords generally are not complex.

The private key should never be copied toВ a machine. You can also disable the root password after the SSH keys are set up.$ ssh-add ~/.ssh/id_rsa Step 3 вЂ“ Copy the Public Key to yourВ nodeNow you can copy and add your public key id_rsa.pub file, to set up SSH on your node under MyAccount.You can usually get this key by copying the results of: cat ~/.ssh/id_rsa.pubPaste the results generated from id_rsa.pub to the SSH section under MyAccount.YouВ may add multiple SSH keys &В can provide a label to each SSH key for easy identification & management purpose.Copy the public key directly to a server (Alternate Approach)The command ssh-copy-idВ can be used to install anВ authorized keyВ on the server.IfВ you donвЂ™t have SSH access to the server then it willВ require aВ root password which is shared with you in the email.Once the key has been authorized for SSH, it grants access to the server without a password.Use a command like the following to copy SSH key:Enter the following command to copy your public key to your Node: ssh-copy-id will copy your public key to the authorized_keys file on your server.Make sure to replace xxx.xx.xx.xx with your actual Ip address and replace user with your actual username in the above command.Once you enter the ssh-copy-id command, you will see information similar to this: The authenticity of host 'xx.xx.xx.xx (xx.xx.xx.xx)' can't be established.RSA key fingerprint is b1:2d:33:67:ce:35:4d:5f:f3:a8:cd:c0:c4:48:86:12.Are you sure you want to continue connecting (yes/no)? yesWarning: Permanently added '12.34.56.78' (RSA) to the list of known password:Now try logging into the machine, with 'ssh and check in:To make sure we haven't added extra keys that you weren't expecting.Only the public key is copied to the server. The system will unlock only when the two keys match. Every time you access your node, the SSH system will look up for the private key pair of the public key added to it. The corresponding private key pair will be saved on your local PC.
