… the ability to instantly brute force AES-256 encryption.
I’m confused by this. It can’t be this elaborate troll?

Calculate time taken to break AES key
A 256 bit AES key is required to be broken using the brute force method on a 2GHz computer. How long would it take to break the key in the best case and in the worst case situations? Assume that 1000
To put it another way: The Sun will die out in a paltry 5* 109 years. In that time, the ratio of the progress you’ve made to the total amount of work you have to do is within a couple orders of magnitude of the ratio of the mass of one hydrogen atom to the mass of the supermassive black hole at the center of the galaxy. However, Wikipedia lists the heat death of the universe as occurring at earliest in 10*100 (10 to the hundredth power) years, so you will crack it by then.
Illuminating?

I guess that even using a quantum computer it would take a few thousand years to break aes 256 key. Or a few seconds if you make a right guess.

NIST Announces First Four Quantum-Resistant Cryptographic Algorithms
Federal agency reveals the first group of winners from its six-year competition
existing crypto algorithms may be vulnerable in a world where general purpose quantum computers exist. Jam’s link above is applicable to X86_64 CPUs. It is functionally impossible to brute force current algorithms which allows us to establish federated trust relationships knowing that who we want to have access can have access and we keep out everyone else. If this trust breaks down … its a very bad day.
Quantum computers don’t work on the same principles and have the ability to do some types of calculations significantly faster than we can today. Work has been underway for over a decade (that link highlights a 6 year contest) to attempt to make these algorithms resistant, and let’s hope they’ve done that. Problem is nobody really knows what quantum computers may be able to do since they’re still essentially lab only type machines.
for example, did any of you imagine the world you’re in now the first time you fired up quake 2 on your lets see back then celeron 300 or intel 333? think about all the advancements in languages, advancements in raw horsepower, GPUs, or the fact that your phone is significantly stronger than the computer you played quake 2 on.
we’re working to make the algorithms ‘resistant’ to what we think the first few generations of functional (outside of a lab) Quantum computers may be able to do. we have no idea how quickly quantum computing may advance though as now we have generative AI. What if you’re running GenAI on a Quantum stack? Can you iterate through the design process and go from a 1.0 product to 10.0 in a year or two? Nobody knows. If that were to happen though, the amount of power that would represent is pretty scary in the wrong hands … or even the right hands.
Imagine having the ability to take all the Lithu coins in existence and make it appear to the block chain to be valid requests.

you’re basing this assumption off what exactly? CPUs/GPUs today aren’t quantum computers. They’re significantly slower in the types of math cryptography requires, which is why crypto works.
Qbits aren’t bound by the same constraints.

You hit all the tech buzzwords in that post…quantum, AI, blockchain…even named your preferred cryptocurrency! Congrats!

i am wondering if it is worthwhile for me to be a’scairt for y’all.
as for me, i am unhackable. well, except for LOT, i guess,

I’m basing it on an article I read a couple of years ago. I’ll try to find it but it doesn’t matter, I don’t know shit about encryption, so I’m not sure if I should even speculate, really.

How can you not be sure you should speculate? It’s been required here for years!

i gave you the link to the actual experts that are tasked with maintaining what little trust we can rely on. NIST are the standard bearers.
“NIST constantly looks to the future to anticipate the needs of U.S. industry and society as a whole, and when they are built, quantum computers powerful enough to break present-day encryption will pose a serious threat to our information systems,” said Under Secretary of Commerce for Standards and Technology and NIST Director Laurie E. Locascio. “Our post-quantum cryptography program has leveraged the top minds in cryptography — worldwide — to produce this first group of quantum-resistant algorithms that will lead to a standard and significantly increase the security of our digital information.”
Now the post I specifically responded to above, about the government regulations. The reason they all ‘suspiciously match word for word’ is likely because NIST believes the work they’ve done will stand up to 34 qbits worth of computing power is my informed guess. Anything above that they’re not sure about, yet. Meaning, the language came from NIST.

CCC | Second Factor SMS: Worse Than Its Reputation
Der Chaos Computer Club ist eine galaktische Gemeinschaft von Lebewesen für Informationsfreiheit und Technikfolgenabschätzung.
It’s been common knowledge for years that SMS isn’t safe. Why do banks and major tech companies still push it?
“Add your phone number to avoid being locked out of your account!”. No you irresponsible and ignorant cunts.

As a tech demo vid, the above fails pretty hard in an amusing way.
First there’s the obvious cut to not show how long it took Gemini to work out the answer to the question.
Second there’s the way they sped up the footage to not show how slow the gimped robot moved (but somehow made it look slow despite that.)
Third there’s the pained look of sadness on the engineer’s face in the video thumbnail:

The company I work for is affected by this:
Computers crashing and then can’t reboot. People where I work have been told to attempt to boot in safe mode and, if that fails, BYOD (use their own PCs). I’m a contractor so already use my own laptop and I wouldn’t put that shit on my machine even if I’d heard of it before today.
I’d hate to be a CrowdStrike employee right now.
