Support keys generated using -O no-touch-required with ssh-keygen #167
Description
I am not able to use keys generated using -O no-touch-required option with ssh-keygen. One of the nice things of Onlykey is that I need to authenticate against the device, so an unlocked Onlykey means that I already confirmed I know the PIN. From then on, it is convenient to not have to confirm presence for every SSH operation.
I use during my development work and it adds friction to automated flows to require me to touch the device on operations like pushing commits to Git repos or running ansible playbooks.
