Working with SSH keys

On your computer, generate a key with the following command:
- ssh-keygen -t rsa
Walk through the steps, passphrase is optional.

Publish the key to remote:
- cat ~/.ssh/id_rsa.pub | ssh user@123.45.67.89 "cat >> ~/.ssh/authorized_keys"
When you get the output that the folder does not exist, use the following command:
- cat ~/.ssh/id_rsa.pub | ssh user@123.45.67.89 "mkdir ~/.ssh; cat >> ~/.ssh/authorized_keys"

Verify that it all works with:
- ssh user@123.45.67.89
