+Send your public key to trusted parties by copying the output below.  Code Talkers should email them to [[mailto:netcmnd@jonathanhaack.com|netcmnd]]
+  cd ~/.ssh/
+  cat id_rsa.pub
+If you emailed me your key, I can add you to the Code Talkers Hacking Club Git Lab.  Now, you should enable your digital ocean vps for ssh as follows
+  ssh-copy-id username@xxx.xxx.xxx.xxx
+That's it - you should now no longer need to enter your password.  If this is not working, check your configuration using the commands below and try again.  You might need to enable public key authentication.
+  cd /etc/ssh/
+  sudo nano sshd_config
+  sudo systemctl restart sshd.service
+  sudo systemctl restart ssh.service
+Keep those public and private key pairs protected.  If you did not change anything, they have the permissions below.  But we all make mistakes!
