But it’s not the company itself putting those assets up for sale. It’s the court-approved or court-appointed bankruptcy trustee of that company, executing transactions approved by the court. That’s why bankruptcy has to go through court, but it also provides a level of immunity (commonly called “exculpation” in bankruptcy cases) to the individuals actually doing the things ordered by the court.

If it’s illegal to do, a court shouldn’t be ordering it, so the affected people should have to fight the court order before it happens. But it’s not illegal to sell anonymized user data like this, and not illegal to sell employee work-related data, either, in the U.S.

It needs to be a system and a contractual framework that complies with the medical privacy regulations of the place where it’s being used (in the US, HIPAA). I have some doubts about whether specific companies or people will actually comply, or the enforcement of those laws by certain governmental authorities, but I don’t think it’s conceptually impossible to have this kind of tech be compliant with those types of regulations.

on average peoples’ computers

Average people don’t have self-administered computers anymore.

People have work laptops administered by their work IT departments, or they have phones and tablets running iOS/Android. Some children have school-administered Chromebooks, and may never own a normal laptop running a traditional desktop OS.

The main people operating self-administered traditional computers are PC gamers (a dying breed during the current price crisis), freelance/independent workers in the fields who still benefit from a mouse and keyboard for productive work and aren’t provided a computer by an employer, and tech nerds.

Raw lichess data shows that 13% of their games involve a pawn promotion too. Maybe the main character is a pawn who gets promoted, and that’s the plot of the game.

Anybody who believed that quantum computing posed a risk to symmetric encryption was fundamentally misunderstanding how encryption works and what quantum computing might be good at one day.

Asymmetric cryptography is primarily used for the secure exchanging of symmetric keys: use a public/private key pair to exchange secure messages of what symmetric key to use for their session, and then both sides switch to the symmetric key for actual communication of a real payload.

A public/private key pair is two keys that have some interesting mathematical relationship, such that it is easy to confirm that someone possesses the right private key using the public key or to encrypt something that only the correct private key can decrypt. And that mathematical relationship, relating to the product of two very large prime numbers, is at the core of modern asymmetric cryptography.

Quantum computing may make number factorization much, much easier. So once a product of two large primes becomes possible to factor, the public/private key pairs might not be as secure anymore.

But none of this has anything to do with symmetric encryption, or hash functions. Quantum doesn’t move the needle on that particular math.

The real risk, though, is for an adversary to eavesdrop on an encrypted key exchange (which uses asymmetric cryptography) and then the message itself (which uses symmetric cryptography) and then be able to take the two steps of getting the secret symmetric key from the intercepted key exchange over a compromised asymmetric protocol, and being able to decrypt the symmetric portion of the communication too.
