SSH Key Setup

1. Generate an SSH Key Pair Open your terminal (Command Prompt, PowerShell, or VS Code terminal) and run: ssh-keygen -t ed25519 -C "your_email@example.com" • If your system doesn’t support ed25519, use: ssh-keygen -t rsa -b 4096 -C "your_email@example.com" • When prompted, press Enter to accept the default file location. • Optionally, set a passphrase for extra security. ________________________________________ 2. Start the SSH Agent and Add Your Key Run the following commands: # Start the SSH agent eval "$(ssh-agent -s)" # Add your SSH private key to the agent ssh-add ~/.ssh/id_ed25519 • On Windows, the key path may be C:\Users\YourUser\.ssh\id_ed25519. ________________________________________ 3. Copy the Public Key Copy your public key to the clipboard: • On Linux/macOS: cat ~/.ssh/id_ed25519.pub | clip • On Windows (PowerShell): Get-Content $env:USERPROFILE\.ssh\id_ed25519.pub | Set-Clipboard Or open the file and copy its contents manually. ________________________________________ 4. Add the SSH Key to Your Git Provider For GitHub: 1. Go to GitHub SSH Keys settings. 2. Click New SSH key. 3. Paste your public key into the field. 4. Give it a title and save. For Azure DevOps: 1. Go to Azure DevOps SSH Keys, then User Settings > SSH Public Keys. 2. Click Add. 3. Paste your public key and save. ________________________________________ 5. Test Your SSH Connection Run: ssh -T git@github.com • For Azure DevOps, use: ssh -T git@ssh.dev.azure.com You should see a success message (e.g., "You've successfully authenticated"). ________________________________________ 6. Use SSH URLs for Git Operations When cloning or adding remotes, use the SSH URL, e.g.: git clone git@github.com:username/repo.git ________________________________________ You’re now set up to use SSH keys for Git authentication!
