GeneratingSSH Keys

Westrongly recommend using an SSH connection when interacting with GitHub. SSHkeys are a way to identify trusted computers, without involving passwords. Thesteps below will walk you through generating an SSH key and then adding thepublic key to your GitHub account.

Tip:  Werecommend that you regularly  reviewyour SSH keys list  and revoke any that haven‘tbeen used in a while.

First, weneed to check for existing SSH keys on your computer. Open up the command line and type:

Check thedirectory listing to see if you have files named either  id_rsa.pub  or  id_dsa.pub . If youdon‘t have either of those files, go to step 2. Otherwise,skip to step 3.

Togenerate a new SSH key, copy and paste the text below, making sure tosubstitute in your email address. The default settings are preferred, so whenyou‘re prompted to "Enter a file in which to save the key", justpress Enter to continue.

Next,you‘ll be asked to enter a passphrase.

Tip:  Westrongly recommend a very good, secure passphrase. For more information,see  Workingwith SSH key passphrases .

Whichshould give you something like this:

Then addyour new key to the ssh-agent:

Openthe ~/.ssh/id_rsa.pub file with a text editor. This isyour SSH key. Select all and copy to your clipboard.

Now thatyou have the key copied, it‘s time to add it into GitHub:

1.      In the user bar in the top-rightcorner of any page, click  Account settings .

2.      Click  SSHKeys  in the left sidebar.

3.      Click Add SSH key.

4.      In the Title field, add a descriptivelabel for the new key. For example, if you‘re using a personal Mac, you mightcall this key "Personal MacBook Air".

5.      Paste your key into the"Key" field.

6.      Click Add key.

7.      Confirm the action by enteringyour GitHub password.

To makesure everything is working, you‘ll now try SSHing to GitHub. When you do this,you will be asked to authenticate this action using your password, which wasthe passphrase you created earlier.

Openup the command line and type:

You maysee this warning:

Don‘tworry! This is supposed to happen. Verify that the fingerprint in your terminalmatches the one we‘ve provided up above, and then type "yes."

If thatusername is yours, you‘ve successfully set up your SSH key! Don‘t worry aboutthe "shell access" thing, you don‘t want that anyway.

If youreceive a message about "access denied," you can  read theseinstructions for diagnosing the issue .

If you‘reswitching from HTTPS to SSH, you‘ll now need to update your remote repositoryURLs. For more information, see  Changing aremote‘s URL .
