Jul 25, 2019 This post will be pretty straightforward and will cover Windows, Mac, and Linux on how to generate SSH keys for Git authorization. A straightforward post covering a step-by-step approach for Windows, Mac, and Linux users. Jul 09, 2018 “How to Add an SSH Public Key to GitHub from an Ubuntu 18.04 LTS System” covers the entire process of creating an SSH key pair on an Ubuntu 18.04 LTS system and adding the public key to GitHub. If you're unsure whether you already have an SSH key, check for existing keys. If you don't want to reenter your passphrase every time you use your SSH key, you can add your key to the SSH agent, which manages your SSH keys and remembers your passphrase. Generating a new SSH key. Open Terminal Terminal Git Bash. Generating a new SSH key Open the terminal. Paste the text below, substituting in your GitHub email address. When you're prompted to 'Enter a file in which to save the key,' press Enter. At the prompt, type a secure passphrase. For more information.

SSH keys are an access credential used in SSH protocol (Secure Shell) which is a network protocol that helps to login from one computer to another securely, as well as to manage networks, operating systems, and configurations. This snippet is going to help you add an SSH key to the ssh-agent, generate a new SSH key, learn how to find the SSH key of your PC and how to connect it with your GitHub/bitbucket account. You can also find information on the use of SSH keys.

Now let's find out how we can checkout PC's SSH keys.

Checking PC's SSH Keys

Type ls -al ~/.ssh so as to see your ssh keys:

By default, the filenames of the public keys are one of the following:

Generate a new SSH key

Type this below, using your GitHub's account email:

The following text will show up after which you can hit the “Enter” button:

In this section, you can hit “Enter” again or type the secure passphrase (more about passphrase).

Adding an SSH key to the ssh-agent

Now let’s find out how we can add the SSH key to ssh-agent. Before adding, check your ssh keys or generate a new key.

Be sure ssh-agent is enabled:
Add your SSH key to the ssh-agent. If you used an existing SSH key rather than generating a new SSH key, you would need to replace id_rsa in the command with the name of your existing private key file:

How To Add SSH Key To Github Account

Log into your Github's account. In the top right corner of any page, click your profile photo, then click Settings.
In the user settings sidebar, go to SSH and GPG keys.
Click New SSH key.
Type Title and your SSH Key.

You can get your ssh key by typing below.

Now you have added your PC's SSH key to your Github's account.

Back up old SSH keys

If there are existing SSH keys, but you do not want to use them for connecting to Bitbucket Server, you should back up these old keys running the following:

Why we need SSH key (for Linux and OSX)

If you use Git and want to clone anything from remote repositories, you have to choose one of these two ways: HTTPS or SSH. If you use HTTPS, you have to type your account access every time you communicate with the remote repository, or change your configs and fill your account data (access). Another modern way is to use the SSH authentication method. It is used in many Version Control Systems to have command line access into your servers, etc. SSH key pairs can be used for authentication instead of passwords. Each key pair consists of a private key and a corresponding public key. When you use SSH key for Git, you inform Git that this PC is authenticated for that Github account, and it will never ask you about any access again because you have already given it your SSH key.

1. The first thing that we need to do is create an SSH key pair to use. Creating this key pair will allow us to add the public key to GitHub. Open a terminal and enter the following command to create the SSH keypair:

2. After entering the command, a prompt appears with a default file path confirmation. Press Enter to accept the default file path.

3. Next, a password prompt appears. Our goal is convenience, since our public key is being created exclusively for GitHub. Leave the passphrase empty and press Enter.

4. Another prompt appears, this time asking for the passphrase confirmation. Leave this prompt blank as well and press Enter.

5. After passphrase confirmation, our SSH key pair is created and saved within the default file path that we accepted in step 2 of this tutorial. We will need to copy the entire contents of our public key to add to GitHub. To display the contents of the public key, enter the following command into the terminal:

6. The output of the previous command should display the contents of the public key like in the image below.

7. Highlight and copy the entire output of the previous command. Every part must be copied for the SSH key to work when added to GitHub.

8. Now that the public SSH key has been copied to the clipboard, open a web browser and navigate to GitHub, then log in to your account.

9. Click the account icon on the navigation bar on the top-right of the page. Select ‘Settings’ from the dropdown menu that appears.

10. Select ‘SSH and ‘GPG keys’ from the selection pane on the left of the page.

11. Click the green, ‘New SSH key’ button on the top-right of the page.

12. We are taken to the ‘Add New SSH Key’ page. First, enter an identifying title for the SSH key so discerning which computer the matching private key is on is easy.

13. Finally, paste the public SSH key that was copied in step 7 of this tutorial into the ‘Key’ text field.
