This is a old thread that got bumped.  OP has not logged in since:

We all know it is very hard and not going to happen without significant cost.  But even if you were able to do it OP has not logged in for anyone to get hash from him.

This thread should be allowed to sink to the depths of the forum Smiley

I can do that, but 1000$ prize can not cover electricity expenses for
cracking your hash. Sorry.

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.


nice exclamation

This to me is further proof that the sha256 used in Bitcoin is bulletproof or it could have been cracked and the OP did not report back, due to criminal intent. Out of curiosity, did any of the members attempt this or did the OP not respond to your request for more information?
There was a guy on reddit who posted his BIP38 paper wallet {Address & Private Key} and challenged people to Bruteforce it, and I wonder how successful that was?

I prefer Zakir over Muhammed when mentioning me!
Please check the date. OP isn't online since January. This bounty is not active. Please don't bump this anymore.

PM me the hash.  I wont waste compute time but I have a list of hashes generated from common dictionary words and phrases that I can see if there is a match.

Please do not PM me loan requests!
I can try this if you like, send me any unsalted hashes and I'll give it a try.

I think it's really not possible unless you have big CPU power
It has a chance of working if it was generated with a phrase.

IMO better off guessing the hashes than actually trying to work out the algorithm lol.  Don't have too good of a chance to crack SHA-256 even with the fastest group of supercomputers anyways.

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

There $1000 bounty would cover nowhere near the power needed to run and maintain the computer xD
Maybe some super efficient computer with 10 PHz running on 1 W of power  Tongue

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.

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

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

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

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

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

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