This Ansible role generates a unique public/private ssh keypair for each host (ssh client), and then copies the public key to an ssh server. This allows for quickly setting up ssh access to 1 server from many hosts in Ansible's inventory.
This would be useful when setting up ssh access for restic or borgbackup where you would need to setup many ssh clients with access to ssh into one target server.
