Quantum computers could feasibly do it. However, even Google’s project willow at 105 qubits is not enough. Because if it were, we would have much bigger problems like, oh, I don’t know, the encryption that protects your bank account and HTTPS connections.
Comment on Is there any security in the communication with Voyager I?

I don’t know the exact numbers off the top of my head, but I believe all the computing power on Earth right now would take on the order of at least thousands of years to brute force a good password hash (assuming a strong password), and that’s assuming the attacker already has the salt. This makes it less of a budgetary constraint and much more of a practical one.

Post-quantum encryption is a thing.

That’s true. I just don’t know of a lot of mainstream things that have deployed it quite yet. Like I do not think HTTPS is post quantum secure, or at least not that I’m aware of.

Correct. But also xkcd.com/538/ . Hence why I said “or bribes and kidnappings”.
