crack my sha256 hash, reward of up to $1000 USD

I would prefer to leave it at 1 BTC, but definitely up to $1000 USD

I can't find anyone to do it for me

[DeathAndTaxes]

It is not economically feasible.  Not at $100, not at $1,000, maybe at $100,000. 

[tacoman71]

Well I got nothing better to do so can you PM me the hash?

[Flashman]

I just read somewhere that the energy required to brute force a SHA256 hash is greater than that available from the Sun... in total... ever.

However, if this is not some random bounty for a very randomly chosen hash, and you might have used English words and phrases to generate a passphrase seed for the hash, then it might be possible to break it in a less than infinite time frame.

If you've got any clues as to the sources of phrases, i.e. "Might be something from a Harry Potter" book, then someone might even manage it this year. Most clues you can give, the higher chance of success, assuming this is attempting to recover a wallet with forgotten passphrase.

Anyway, good luck with that, as they say.

In his countless other threads OP indicated it is 10 digits random (A-Z,a-z,0-9).
So 10 digits @ 64 values per digit  64^10 = 83,929,936,5868,340,224 combinations
7970 is ~ 1 billion SHA-256 attempts using hashcat.

83,929,936,5868,340,224 / 1,000,000,000 / 60 / 60 / 24 / 365 = 26 GPU years.  50% chance in half that so 13 GPU years.   Someone with a 13 GPU farm running 24/7/365 for an entire year would have a 50% chance of cracking it.

$1,000 is a joke.

[Wipeout2097]

Are you guys really experienced at cracking in the real world?

[keysersozeTx]

Hah, this cannot be a serious request.. Wouldn't even be ROI+ with the cheapest GPU enhanced botnet in history at $100k

okay you're a joke

clearly someone using just 1 gpu should just give up

why don't you mine bitcoins with just your ass cpu

[ampbuster]

maybe she could have done it without relying on electricity

Math vs insults I will side with the math.  
Not sure if it was a reading comprehension problem (nothing in there was about CPUs) or delusion.

[Taras]

I can try this if you like, send me any unsalted hashes and I'll give it a try.

[mineradam]

I think it's really not possible unless you have big CPU power

[jerelimZ]

I might try, but you have to give some hint to these 10 digits random characters/digits

[RogerMendes]

u need to have at least a clue of what the password was... like, number of characters, possible beginning, possible ending, contains letters... without that it's just unfeasable

[nahtnam]

Why don't you post a few below and we can see the hashes.

[geeo]

good luck with this one!

[greenlion]

What could possibly be the purpose of paying somebody $1000 to crack a SHA256 hash other than some misguided criminal enterprise?

[Lauda]

Maybe if you hacked the worlds biggest supercomputer and used that.

Was there a reason why you started this topic, other than trolling/insulting others?

There $1000 bounty would cover nowhere near the power needed to run and maintain the computer xD

[KGBSlim]

Am I the only one thinking this OP has someone elses wallet and wants the contents??? lol....Sorry OP if thats not the case but if you know what SHA-256 truly is, which most non beginners in the bitcoin world do, you would not even be asking the question. If it was that easy, bitcoin wallet hacking would be a widespread olympic event in the Hacker world.
