Generating ssh key (public and private)

1. Open terminal
2. Run ssh-keygen command
3. When prompted for filename to save, press enter for default location
4. When prompted for passphrase, you can either put in a passphrase (highly recommended), or just leave it empty (not recommended)
5. Your public key is /home/username/.ssh/id_rsa.pub, and your private key is /home/username/.ssh/id_rsa
