Viewing your keys on macOS can be done in similar fashion as Linux. The above command will print out your SSH key on your Linux machine, without prompting you for your key authentication password. If you don’t want to have to memorize yet another command, you could simply use the cat command like so: cat ~/.ssh/id_rsa.pub Of course, that’s a lot of commands to remember, especially when you just need to view the contents of the public key.
You can then copy that and paste it where you need. Upon successful authentication, your SSH public key will print out in the terminal. The command is: ssh-agent sh -c 'ssh-add ssh-add -L' This is probably overkill for what you need, but it’s a good way to view the key, while requiring your SSH keypair password. The first method is a bit complicated, because it makes use of both ssh-agent and ssh-add commands. There are two easy ways to view your SSH public key in Linux.

To SSH to your EC2 instance from your Mac, just go back to your terminal (or launch it again if you’ve closed it already), navigate into the directory that contains your private key file, and then enter: ssh -i. Once you’ve launched the instance, take note of its Public DNS hostname or Public IP address, as you’ll also be needing either one when you connect via SSH. I won’t go into the details of creating a Linux EC2 instance, as that should belong to a separate post, but once you launch such an instance, you need to select the key pair you created so that Amazon EC2 will know what private key file to expect when you connect via SSH. You can now start using your private key to authenticate to your Amazon EC2 Linux instance via SSH. Navigate to the directory that contains your private key file and then enter: chmod 400 nameofyourpravatekey.pem

Although you can generate a public-private key pair using a third party tool and then import the public key on Amazon EC2, we are going to go through the usual route which is to generate keys from Amazon EC2 itself.
SSH logins are typically done through public key authentication, which requires users to have their private key on hand. We’re using a Mac, so some of our screenshots are going to be taken from a Mac UI. In this post, we’re going to show you how to connect to a Linux EC2 instance via SSH. having no graphical user interface (GUI), you need to access them through the command line. Since many of these Linux instances are headless, i.e. For quite some time now, Linux and its derivatives or distros have been the most widely used platform in the cloud.
