What is the closest crypto analog to this kind of key?
I think the physical key has the same blade shape on either side.
The companion software would decrypt the ciphertext but prevent exporting the cleartext, forcing the user to first re-encrypt the text first.

Also this clock design seems unnecessarily inefficient. Why divide 24 hours in multiple of 5 hours instead of the much more natural 6? This way it would be a lot easier to decode AM/PM.
I realize that it's about art more than practicality but I don't really understand why that encoding was chosen.

You can't leave through my (brand new, to-code) front door from inside without a key to unlock it first. It wouldn't be secure if you could open it without a key - isn't that the whole point of a lock with a key?

What country do you live in? In the US, almost every door I’ve ever seen can be unlocked from the inside (but not the outside) without a key.
I'm surprised some houses still use this. As it's impossible to leave the building without a key in case of a fire. I suspect it may even be illegal today.
As an American living in Switzerland one thing that has consistently surprised me is the difference in fire safety rules: not having any smoke alarm or fire extinguishers in homes is common, and it's also common to be able to lock people inside rooms/apartments/buildings so that they can't leave without having a key. It's possible to lock someone in my apartment even if they have the key if the door is locked with th…
However in the end you are responsible for your own safety. If you are in a room with a lock, make sure you don't lock yourself in. Locking people in is a bad idea regardless of situation (and I am pretty sure it is illegal to do so against their will).
