Securing Your GitHub Account with SSH Keys

Working with source control in your own public or private GitHub repository will be a common occurrence for most system administrators. Through the use of standard SSH tools, the student will learn how to generate a special SSH key that can be used to secure access to a private repository. At the end of this learning activity, the student will know how to generate, add, and use this SSH key to secure their access to private repositories.

Challenge

Create the SSH Key to Use to Secure Access to GitHub
Creating a specific key to be used to authenticate the 'cloud_user' account on the provisioned system with your GitHub account can be done as follows:
```
ssh-keygen 
```
Now we need to view the contents of the file that was created:
```
cat .ssh/id_rsa.pub
```
Let's copy it. Over in our GitHub account, if we get into our account's Settings, there's a menu option (on the left) for SSH and GPG keys. In there, we can click New SSH key. There's a web form here. Let's give our key a meaningful name (like lab server) in the Title spot, and paste our key's contents into the Key spot.
Challenge

Create a Git Clone
Now we can create a Git clone:
```
git clone [email protected]:linuxacademy/content-source-control-git.git
```
After we run that, we'll get the usual The authenticity of host... message. We can just type yes here, and should see the Git repo get cloned locally.
