By default ssh-keygen uses an insecure password encryption method on the ssh key.
This change will add options to better protect the key.
See this page for more detail: https://latacora.singles/2018/08/03/the-default-openssh.html

Even if the user does not set a password, using the `-o` option needs to become
the new standard way to run `ssh-keygen`, since the default behavior is insecure.
Your help in establishing this option will be greatly appreciated and will help
improve overall security for your users and ssh users in general.
