The cryptography behind SSH keys ensures that no one can reverse engineer your private key from the public one. Generating an SSH key pair. The first step in using SSH authorization with GitHub is to generate your own key pair. You might already have an SSH key pair on your machine. At Creating a SSH key for GitHub: Open PuTTygen, generate a key and save your private key. Mark the key in the text area and paste it into your github account settings (SSH Public Keys→Add another public key). Check out the GitHub SSH guide for PuTTygen (keep your passphrase empty by the way) (give your key any name on GitHub).
