How to connect to github via ssh

SSH (Secure Shell) is a network protocol used to establish secure connections in insecure networks. As a code hosting platform, Github provides the function of using SSH connection, which can improve the security of the connection. So this article will detail how to connect to Github via SSH.

Step One: Install git

We need to install git, a popular version control system, so that we can interact with the code on Github locally. If you already have git installed, skip this step.

For Linux users, execute the following command to install git:

sudo apt-get update
sudo apt-get install git

For Mac users, you can install through the Homebrew command:

brew install git

For Windows users, you can use Git Bash Or download the executable file to install. After the installation is complete, open a terminal and run the following command to verify that git is installed correctly:

git --version

If you can see the output, git has been successfully installed on your computer.

Step 2: Generate SSH key

We need to generate an SSH key for authentication when connecting to Github. Open a terminal window and enter the following command:

ssh-keygen -t rsa -b 4096 -C "youremail@example.com"

When prompted for a file name in the SSH key generator, you can use the default value (i.e. ~/.ssh/id_rsa).

After clicking the Enter key, the system will prompt you to enter your password. If you want to leave your password blank, just enter the Enter key twice.

After the key is generated, your SSH key can be obtained with the following command:

cat ~/.ssh/id_rsa.pub

Copy the entire contents of the public key to the clipboard, this will be used in the next step.

Step 3: Add SSH keys to your Github account

On the Github website, click the user avatar in the upper right corner of the page -> Settings -> SSH and GPG keys - > New SSH key. In the Title field, provide a title to identify the key. In the Keyword field, paste the SSH public key you just copied to your clipboard. Once done, click the "Add SSH key" button.

Step 4: Test SSH connection

The last step is to test your SSH connection to see if you can connect to Github normally. Enter the following command in the terminal:

ssh -T git@github.com

If everything is fine, you should see output similar to the following:

Hi yourusername! You've successfully authenticated, but GitHub does not provide shell access.

This indicates that you have successfully configured the SSH connection.

Summary:

In this article, we have detailed how to connect to Github via SSH. First you need to install git and then generate an SSH key. Then add the SSH key to the Github account and finally test the SSH connection. This will ensure your Github connection is more secure and reliable.
