coreos-cryptagent is the utility used by Container Linux to unlock encrypted disks at boot time, directly in initramfs.
It is meant to complement Ignition first-boot setup, taking care of activating volumes on subsequent boots.
On typical a run, there is no direct user interaction. Unlocking is triggered via udev events, and volumes are automatically processed based on relevant configuration entries.
To report bugs, please use the common CoreOS bug tracker.
