  • Combo of
    • Perl for Installation,
    • ssh-keygen for key exchange.
    • udev for actions
    • bash for locking/unlocking/key checking.
  • udev add/remove/change events
    • add event does not allow access to drive
    • change event was not allowing unlock.

Compromise was unlock, then lock if key check fails.

Great technique

Thanks so much for the tip!
