Dunno about you, but I'd trust two pilots, 150 passengers, and six
terrorists over one maybe suicidal pilot and some complex crypto B.S.
any day.

It'd make way more sense to just have a button on the outside that WILL
open the cockpit door in 60 seconds that also sets off a very loud alarm
that clearly states someone is trying to get into the cockpit - the
chance of the passengers not being able to overpower any hijackers in
the event such an alarm is triggered is way smaller than the chance of
another Germinwing happening.
