Encryption Cracking

[Guest]

I've been told that some encryption algorithms can take up to something like a hundred years to crack, and I was wondering

 

Would it be possible to just copy the data onto a different device/devices and then have each device try using a set of methods that would attempt cracking the encryption? Like to save time, each device handles a different set of cracking attempts. 

 

I have a feeling the obvious answer will be no because it's such a basic question but I figure I would be sure and ask

Even if you do it,with all the devices in the world combined it would still take hundred or even a thousand years to crack,let alone a single device

 

If you want to crack something like that,just use a Quantum Computer as it will be MUCH MUCH MUCH MUCH MUCH MUCH MUCH¹⁰⁰⁰ faster

From what I've heard, back with the encrypted iPhone issue (where a shooter was supposedly affiliated with a terrorist organization and the US government wanted to decrypt his phone), the company that broke the encryption simply cloned the iPhone onto another iPhone, had a program attempt some pin combinations, and if the device got locked, it would just clone the original again.

 

Being that this is a 4 digit pin, and assuming it takes 1 second per combination attempt, it would take about 2.7778 hours (10^4 combinations, not including the time it takes to clone the device).
Sure, it'd be more efficient to spread the workload across multiple devices, but cutting down from a thousand years down to a hundred is still pretty pointless.

 

As keNNYSOC said, quantum computers would be the only real way to decrypt most things in your lifetime, unless you have hundreds of spare computers with an enough processing power to rival a modern super-computer.

I feel that your statement may be flawed as I did not specify exactly what type of encryption, just an estimate

I'm confused on your transition there

 

You started off by saying the iPhone got cracked and it was encrypted and then went on to say that quantum computers would be the better idea

 

I seem to disagree with the idea of quantum computing

Oh I think you mean that the encryption itself being cracked is pointless, but rather to find another way in would be a better idea if it were the case as you said with the case with the iPhone. My understanding is that the encryption itself would be solid standing but another method to use instead would be a better idea, such as password/passcode cracking.

That's the only fast way your gonna crack something that takes thousands of years for all computers to do something like RSA4096

Yeah, what I meant was that encryption uses keys, and using an example of a typical iPhone pin being 4 digits (AKA the key being 4 digits), it's still very difficult to crack its encryption. Diverting the work to multiple devices helps, but quantum computing blows everything else out of the water in every way possible. If articles I read are true, Google's quantum computer is roughly 100 million times faster than an average laptop, so you can imagine cutting down the time to brute force an encryption by 100 million times is amazing.
