This guide goes through setting up SSH keys on macOS Mojave 10.14 back to Mac OSX 10.11 and also a secure password-less SSH connection between a local macOS workstation and a remote server also running a Linux variant operating system.

The process requires generating a public and private key on the local computer and then adding the public key to the remote servers authorised list. What is great about this is that it allows a password prompt free session, handy for a lot of uses.

First thing that you need to do on your macOS machine is to create a directory that will store your SSH keys. Then you will generate a public and private key for your account, launch the Terminal and punch in some commands:

Create a .ssh Directory

SiteGround uses key pairs for SSH authentication purposes, as opposed to plain username and password. More information on SSH keys is available here. You can generate an SSH key pair in Mac OS following these steps: Open up the Terminal by going to Applications - Utilities - Terminal. Apple Root Certificates. Apple established the Apple Root Certification Authority and the Apple PKI in support of the generation, issuance, distribution, revocation, administration and management of public/private cryptographic keys that are contained in CA-signed X.509 Certificates.

Apr 09, 2014 In this tutorial, you will learn how to generate a key pair on a Mac OS X system. The key pair generated here is used for testing purposes only and is self-signed. The public certificate generated can then be used for testing SSL Mutual Authentication from a browser to Forum Sentry. In Mac OS X, key pair generation, storage and management is. The CSR public key you will give to a Certificate Authority (CA) for signing and the private key will remain hidden on the Apple Mac OS x 10.6 system where the CSR request is made. With Mac OS X you will first create your own self signed keypair, and then extract your CSR from it in order to give your your Certificate Authority (CA) for enrollment of a SSL certificate.

Change to the home directory

Public Key Example

• MacOS is based on the Unix operating system and on technologies developed between 1985 and 1997 at NeXT, a company that Apple co-founder Steve Jobs created after leaving Apple in 1985. The 'X' in Mac OS X and OS X is the Roman numeral for the number 10 and is pronounced as such.

Create a SSH directory name .ssh and move into it

Make sure that the file permissions are set to read/write/execute only for the user

Create your private and public key, the blank quotes at the end of the command gives the private key no password, so allowing for passwordless logins!

Change into the .ssh directory and list the contents of that .ssh directory

Thats your SSH keys created, the private key is the id_rsa and the public one is the id_rsa.pub, don’t give out the private one always keep that one only on your local machine.

Sharing the Public Key

Create an authorized_keys in the .ssh directory of the remote computer that you want to connect to.

You can create automatic logins by adding the contents of your public key to the authorized_keys file on the remote device.

What Is Public Key

To see and copy your public key use the cat command and copy the contents:

On the remote computer if needed, change the permssions on the authorized_keys file to write to add the public key, on a new line paste in your public key, and change permissions back to read only after for security.

Allow write on authorised_keys

Paste the entire id_rsa.pub content with vi or nano into the authorized_keys file, if using nano use the -w flag to not use incorrect line breaks.

If the remote host does not have an “authorized_keys” file simply create one and after the public key is pasted in don’t forget to takeaway write permissions.

Going Both Ways

So now when you connect via SSH no password is prompted as the remote computer has your public key which is only decrypted by your private key held in your local .ssh/ directory. If you want the communications to be bilateral then repeat the process in the opposite order between the two.

Now the two computers can securely connect with no password prompting, making it ideal to script between the two for file copies or back ups.

Doing it Quicker

Now instead of typing in

Make an alias in your bash shell you could alias it to

Reload the the shell

Then all you have to type in is the alias
