1. What is Git Config SSH Key?

In the realm of Git version control system, Git Config SSH key or Git SSH key refers to the SSH (Secure Shell) key used for secure authentication between a local Git repository and Git hosting services (such as GitHub, GitLab, and Bitbucket) while performing various Git operations.

Unlike HTTPS, which requires constant authentication during remote repository interaction, Git SSH keys provide a more seamless and secure approach by using cryptographic key pairs. These key pairs consist of a public key that resides on the Git server and a private key stored locally on the user’s machine.

When you configure Git with your SSH key, it allows you to authenticate your Git actions without repeatedly entering usernames and passwords, creating a convenient and secure environment for managing your codebase.

2. Generating SSH Keys

Before diving into configuring SSH keys in Git, we first need to generate the key pair.

To generate SSH keys, you can follow these steps:

  1. Open your terminal or command prompt.
  2. Enter the following command:

“`shell$ ssh-keygen -t rsa -b 4096 -C “”“`

This command generates a new SSH key pair using the RSA algorithm with a bit length of 4096. You can provide your email address as a comment to identify the key later.

Next, you’ll be prompted to choose a secure passphrase for your private key. While optional, using a passphrase adds an extra layer of security to your SSH key.
