🔑 SSH Keypair Setup for GitHub (or GitLab/BitBucket, etc)

🏞️ Create the Repository

Make sure there is at least one file in it (e.g., README.md).

🗝️ Generate an SSH Key Pair (private/public)

Generate a new SSH key using RSA:

ssh-keygen -t rsa -C "[email protected]"

Generate a new SSH key using RSA with even better security:

ssh-keygen -t rsa -b 4096 -C "[email protected]"

Generate a new SSH key using ED25519:

ssh-keygen -t ed25519 -C "[email protected]"

⚙️ Create SSH Config

Bash or MacOS:

touch ~/.ssh/config

Windows:

type nul > ~/.ssh/config

Add the following content to the config file:

Host *
  AddKeysToAgent yes
  IdentityFile ~/.ssh/[key_generate_file]

or you can specific host

Host github.com
  HostName github.com
  User git
  IdentityFile ~/.ssh/[key_generate_file]

📋 Copy the Contents of the Public SSH Key

Copy the contents of the file ~/.ssh/id_rsa.pub to your SSH keys in your GitHub account settings (https://github.com/settings/keys).

🚀 Copy the Public SSH Key to GitHub

Paste the contents of your SSH public key into your GitHub account settings (https://github.com/settings/keys).

🧪 Test SSH Key

Run the following command to test your SSH key setup:

ssh -T [email protected]

result:

Hi [Your GitHub Name]! You've successfully authenticated, but GitHub does not provide shell access.

🔄 Update Repository Remote URL

Change directory into the local clone of your repository (if you're not already there) and run:

git remote set-url origin [email protected]:username/your-repository.git

Now try editing a file (e.g., README) and then do:

git add .
git commit -m "Update README.md"
git push

If it works without asking for a username or password, your SSH key is correctly configured. ✅
