How to Use SSH Keys

1. Save Private Key

Save the private key to ~/.ssh/id_rsa (or appropriate name) and set permissions:

chmod 600 ~/.ssh/id_rsa

2. Add Public Key to Server

Copy the public key to the server's authorized_keys file:

cat ~/.ssh/id_rsa.pub >>  ~/.ssh/authorized_keys

3. Connect

You can now connect to the server using SSH without a password.
