Copy public key to your server
Now we will need to take our authorized_keys file and store it on the server, if we can currently login via SSH to our server we can use rsync over ssh to securely copy the public key to the server, Although this key is displayed to anyone who attempts to login to your server it is smart to use SSH or another secure method to copy it up to the server to ensure that the key is not tampered with while it is being transmitted.
Below is an example using rsync to copy the authorized keys file to its destination on the server and removing it from your local computer.
Your web server uses thesigned certificate for HTTPS.As an alternative to using a CA, you can use the AWS CloudHSM dynamic engine for OpenSSLtocreate a self-signed certificate.
