What's wrong with the idea of having a huge computational network like in Watch Dogs to bruteforce encryption ?
I mean suppose having 500 or more million cores , how long does it actually take to bruteforce a 256 bit key ?

If you have 500m cores, they probably dont have 256 bit encryption

@sharktits @LastDigitOfPi thanks for the insights, so how much computational power would it take to get it down for like a minute or so

@LastDigitOfPi I could , but I need a calculator that can handle the numbers 😂

@Lahsen2016 i guess they already exist, like I am holding in my hands a quadcore 2.5GHz, in my drawer there a few phones too ... And the list goes on and on, processors are everywhere

@Lahsen2016 oh okay, thanks :p
Now I wonder why do we have 512 and 2048 and 4096 keys 😂

One-Time Pad FTW :D

I guess instead of bruteforcing the encryption you try and attack implementation instead?

uHm, what kind of encryption are you talking about?

@Lahsen2016 4Ghz CPUs don't exist yet? Uhhh I've been running Intel chips at 5Ghz overclocks for the better part of three years now with only one of those mediocre all in one liquid coolers, even the i7 7700HQ in my laptop can turbo up to 4 something Ghz on a single core, the future is now!

And the new Zen chips and most new Intel chips for any sort of serious prosumer /gamer run at 4Ghz minimum out of the box. My 8700k runs at 4.3 Ghz minimum out of the box on all threads before I took it to 5Ghz.

And maybe a more interesting question is how long would it take to break that encryption with GPUs, probably an infitely long amount of time still with more GPUs than have ever existed but would be interesting to run the math on that one. And I mean theoretically you could hit the number before you run through every possible permutation, in fact I would imagine if you were to run the numbers it might only take you half or a quarter or three fourths of the permutations to hit upon the correct number because it's equally likely that you get a correct answer on the first number you check as it would be on the last (if I recall stats correctly don't quote me on that one). But basically regardless it would still take many lifetimes to realistically crack encryption with the technology we have now.
