#4General question, since I never before read up on why to use Argon:
Why can't programs like Hashcat treat virtual memory (which is just disk space) as "on board memory", and then get 1000 attempts out of each TB?
I would think the calculations themselves are relatively minor, if you are using that amount of RAM.

You need to do random access to the memory buffer, and random access to virtual memory is slower than random access to actual ram, by enough to make it slow.

Governments are formidable adversaries to have. They have amongst other virtually unlimited funds and resources.

My guess would be contact information. He is apparently an anarchist imprisoned for setting fire to cars.

The algorithms are designed, at each step, to need a random memory location — the idea is you had some data, then use that data as the index into your memory.
This means the speed of the algorithm is measured in random memory accesses, and that speed is much slower for discs than RAM, even with SSDs.

Even with the smallest instance types that's around 8 million in compute cost.
Doesn't sound like something you would spend on a small crime?

Multiple possible scenarios:
- He actually gave his password himself as part of a deal with the police which includes this as a cover up.
- The police got his password through another mean they don’t want to disclose and are using this as a cover up.
- They really want a list of his contacts and what they were discussing because they are scared than one of them could be tempted to do more than burn a few cars.
- France has a more computationally effective way to decrypt these drives which has yet to be released.
