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.

Issue the following command at a shell prompt (by default, Mac OS Terminal uses a bash shell): ssh-keygen -t rsa -b 2048 This will create a RSA public/private key pair in the.ssh directory below your account’s home directory. Sep 26, 2019 To generate SSH keys in macOS, follow these steps: Enter the following command in the Terminal window. Press the ENTER key to accept the default location. Type in a passphrase. You can also hit the ENTER key to accept the default (no passphrase). Create an SSH key pair. Use the ssh-keygen command to generate SSH public and private key files. By default, these files are created in the /.ssh directory. You can specify a different location, and an optional password (passphrase) to access the private key file. If an SSH key pair with the same name exists in the given location, those files are overwritten. How do SSH keys work. A key pair will be generated on your local PC. Generating a key pair provides you with two long string of characters: a public and a private key. The public key will be added to your node. The corresponding private key pair will be saved on your local PC. 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 system will unlock.

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

Change to the home directory

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.

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

Generate Ssh Key Aix

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

Generate Ssh Key Windows

Reload the the shell Generate a public key mac.

Then all you have to type in is the alias
