HPR3231: USB Key

Script and instruction at

https://james.toebesacademy.com/USBKey.html

• 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.
