Enter the following command carefully: ssh-keygen -t rsa -b 2048 -C 'John Smith' -f johnJust replace John Smith with your own name (keeping the quotation marks, they're important!). ssh pwdThis should then echo this back to you: /Users//.sshNow we need to generate your keypair. Once Terminal is open, we need to change change directory to the hidden.

Create the keys Open the Terminal application from the Applications/Utilities folder, or press - and search for Terminal using Spotlight.

You can open them in TextEdit.app if you are curious! The key files are just plain text - nothing magical. Because only you have the private key you can always regenerate the public key again from it. It doesn't matter if your public key gets stolen or lost.

The public key can be freely installed on remote systems. The private key remains on your computer and should be kept safe from unauthorised access. Public/private key authentication, as the name suggests, uses two special cryptographic files (called keys) to authenticate your login. MacOS is derived from Unix style operating systems, so understandably, the tools to manage SSH connections are already built in. If prompted, type the passphrase created in 1: Create and save the SSH key files.ДЇor 24-hour assistance any day of the year, contact our support team by email or through your Client Portal.How to use public/private keys for SSH and SFTP (MacOS).If ssh key authentication is functioning properly, you will log in successfully. Issue the following command: ssh Select Yes to accept the key fingerprint.Run the ssh-copy-idcommand with the same arguments used for connecting to the server using the sshcommand: ssh-copy-id the connection If you are not a Nexcess Cloud client, the easiest method-of-transfer uses the ssh-copy-id command.If you cannot find your login credentials, either click Forgot Password? on the login page, or contact our 24/7 support team.

If you lose access to your server due to a lost key, contact our Support Team for assistance. A lost private key cannot be replicated therefore, the user cannot access the server until an administrator generates a new key pair. Users should take special care to not lose the private key.

Each key is useless without the other therefore, only individuals withВ bothВ the private and the public key can gain access to the server, and the private key is never revealed to the server. The private key is known only to the userвЂ™s computer the public key will be known to the server. The process involves generating a pair of SSH key files containing a private key and a public key. See What are the advantages of using SSH keys to control access for multiple users? for details. If you require SSH access for multiple users, the use of SSH keys instead of individual logins can bypass many of the headaches involved in user management without violating PCI DSS.

This longer string has many more possible permutations and therefore takes much more time to crack with a brute force attack.

While a password of eight characters is 72 bits long, SSH keys are often 2048 bits or longer. Keys are more secure than passwords because they are significantly more complex. Each вЂњkeyвЂќ is actually a key pair consisting of a public key and a private key. SSH keys are a means of authenticating a user to an SSH server without using a password.
