Generate SSH Public & Private Keys for GitHub Actions Workflows

To generate a new SSH key pair, run this on Local PC with OpenSSL installed:

ssh-keygen -t ed25519 -f id_ed25519

• This will create id_ed25519 (private key) and id_ed25519.pub (public key) in your current directory.

Store the Private Key as a GitHub Actions Secret

• Go to your repository secrets:
  https://github.com/your_repo/settings/secrets/actions
• Add the contents of your private key (id_ed25519) as a new secret.

Add the Public Key to the Droplet

• Copy the entire contents of your id_ed25519.pub file.
• On your droplet, append it to /root/.ssh/authorized_keys:

cat id_ed25519.pub >> /root/.ssh/authorized_keys

This setup allows GitHub Actions to connect securely to your server using SSH keys.
