Create Key Pair
---------------
A **key pair** is the public key and private key of
`public–key cryptography`_. They are used to encrypt and decrypt login
information when connecting to your server.

them as above and then using the find methods to get the appropriate
resources.
Ideally you'll also create a server using a public/private keypair so you can
login to that server with the private key.
Ideally you'll also create a server using a keypair so you can login to that
server with the private key.
Servers take time to boot so we call ``wait_for_server`` to wait
for it to become active.
