Hi All,

My cousin has a small situation, he uses keypass to keep his passwords nice a safe (and so he remembers them) as he uses strong passwords Capitals, lowercase and numbers. No extra punctuation.

Today his keypass wallet got corrupted and he didnt have a backup so now he has lost 11.7 BTC, unless someone can crack it.

He knows its none of his usual passwords as its a secure one generated on http://strongpasswordgenerator.com/ and could be up to 15 character long.

Now, he has told me he is either willing to get someone to crack it for him and give him some of the btc (25%) or sell the wallet for a fee just so he at least gets some of his money back.

Just wondering if anyone else has any suggestions? are there any crackers out there that can brute force it or reverse engineer it?

he only lost the password 15 minutes ago.

Thanks for any help

you have to try and restore your corrupted keypass files. May be offer a reward for fixing those, without giving away wallet.dat - someone may give it a try. Working on wallet.dat directly is pretty much hopeless in this situation.

Can he remember past of the password, or he has completely no idea what the password is?
If it is the latter case, I don't think it can be brute forced for a 15-character long password...

He thinks it starts with X0

If we are talking about 13 unknown characters in the password, your only bet is to restore the keypass files.

Thanks for the link.

He believes it is more like 8 - 10 characters long. he said it wasn't very big.

If it is 6-8 unknown characters (with 2 known), it is possible to brute force the password.
Good luck :)

Did he delete the files where his passwords were stored or was the file just corrupted for no reason?

If it was deleted there are tons of ways to recover files using a file recovery program.

Happend to me once and that's what I did.

Can I just ask who would buy this?

It sounds like the perfect scam.  Buy an encrypted wallet and try to crack it, after a while, who's to stop the seller from remembering it and just transferring it to another wallet to sell.

I don't know if it is a scam or not. I was just replying to help OP understanding the difficulty of brute forcing the password.
IMO, no one should and would buy a encrypted wallet.dat, but it is possible that OP send the file to a trusted person with ability to brute force it, and split the bitcoin inside afterwards.

It looks like that address has more activity than a lost one would have.

Wait a minute let me get my quantum server out the cupboard and cracked it for you in say 1 year

Has your friend tried to use Recuva to recover the file with the passwords? It's possible it's still recoverable.

Just post the private key and someone will eventually crack it.   ;)

Private key? Looks like it is a typo here. :)

I give you 0.001?

After this post the given address was still being used: https://blockchain.info/address/15Simt9rXvCLgfG7c3KcGWsWYrZfhGv6t1

So most likely a scam attempt ? Or he got his wallet/passwords fixed.

Anyway, no need to make offers ;)

I would buy it if I knew that the wallet truly contained 11.7 BTC. Or just wait for quantum computers to extreme brute force it open  ;D ;D

Bad idea.

I could make a wallet with 11.7 BTC in it with a good 30 character password and sell it to you.  You would never crack it.  Two years later I could then just move it. 

Imagine you spend all that time Decrypting it and the Wallet file is empty? lol.

go to suport and tell them all the information that you know about your acc example
e-mail
Your mobile phone number
old password
second password
try

an old backup before the password, insert that wallet.dat into the client, after removing previous, and he might be good to go - worked for me about 18 months ago

how it is possible to lose the password of the wallet or do you want to hack?

Indeed it is not rare to see people forgetting their password, especially when they created a special "secure long password just for their bitcoin wallet. :)

He found his password back, or it was just an effort to scam. This wallet is being used to receive and send funds.

You are right. There are multiple send and receive transactions on the same day that the thread was created and on subsequent days. The OP might have simply made up that story and posted a random address in order to scam other members. I believe we should err on the side of caution and have this thread reflect on his Trust rating. If he was being honest and the issue simply resolved itself on its own, then he could always post back on this thread with a message digitally signed with the posted address. Frankly speaking though, the OP's account looks like a shill account.

Considering that he disappeared around the time that everyone had called him out on his scam I really wouldn't be surprised that it was a shill. It is almost never worth it to believe these - the wallet they give you is likely not to contain the private key and you will never know until you crack the password. But then since the password is meant to be long and hard to crack by the time you uncover the scam the scammer will be long gone.
