In light of the recent plane crash in Pakistan, reports suggest that it will take 6-7 months to decode the black box.
The company that made the black box surely knows how to decrypt their encryption, so why would it take so long?
Also, assuming the encyrption is super-complicated, what sensitive data would warrant such encryption? Is it just voice recordings, or something more?

Im no black box expert, but from what I know, it’s basically a log of all of the aircraft’s sensors and all of the things the pilots did. Imagine a massive excel file with hundreds of columns(vertical) . Each column is a sensor, be it altitude, aircraft nose angle, air speed, engine power, amount of fuel, door closed sensors, etc, anything you can imagine that an aircraft might have. Then every second, the value of all the sensors fills out a row(horizontal) in that excel file. Well, that’s a shitload of data, and looking through an hour or more of that pure data is going to take a lot of time. You’d be looking for abnormalities in sensor readings or weird combinations of sensor values, sensors that stop working, pilot actions that didn’t result in the expected sensor response, etc. It’s probably just a ton of crap to go through, and unless you find a real “smoking gun” figuring out what exactly happened would take a lot of time a knowledge of the entire aircraft. That make sense?
