The mining process is basically cracking the system and once a certain amount of effort has been reached trying to recover a wallet, it is time to hang it up.  It is up to you when you get to that point and lost funds do suck, but that same amount of effort posting here, searching files and this and that can be applied to getting new funds and that becomes the best path at some point.

Butense, can you pass your wallet.dat into this script? https://github.com/stricture/hashstack-server-plugin-hashcat/blob/master/scrapers/bitcoin2hashcat.py

syntax should be: bitcoin_hash.py wallet.dat > wallet.hash

then post here the content of the wallet.hash file, it should be a string like this: $bitcoin$96$d011a1b6a8d675b7a36d0cd2efaca32a9f8dc1d57d6d01a58399ea04e703e8bbb44899039326f7a00f171a7bbc854a54$16$1563277210780230$158555$96$628835426818227243334570448571536352510740823233055715845322741625407685873076027233865346542174$66$625882875480513751851333441623702852811440775888122046360561760525

It's useful to pass the info to hashcat in the correct syntax.

However, cracking speed seem very slow with this algorithm, so brute force is impossible (except for very short passwords). The only realistic possibility is try possible variations of the list of password you posted in the first post.

bump, can you do this Butense? I know it would be difficoult to find the password, but I want to try.
I see the 0.155 haven't moved, so nobody found the password until now

I apologize for the late response.  Here is the result from that script

$bitcoin$96$3ce2900d6c2df58a1cfa9ea1755a1599e0b60001fcd29d730c298de7538e3a0709e4fdb738d8ac61b5b03c582d724214$16$d07e66c2606ae4fc$80062$96$0d19a16dcbaa53570214fbeea16c65721f5dc28513053de870c7f8437222e3620be2ee0c92b4e3fdd1ef61ef7f20ae96$130$04fec0d307bdda75bc9cd4861a519d92814ef934cae6bddfac84ccf79356d93bc6399d1ca0e6f25dd6b3bb6b5db7d2d505e985e99c6cec46c8604ec203ce7f487e

let me know if you need anything else.  like i said earlier, i doubt that any of the passwords i put on the first page are related to this wallet password, and i cant remember any more, so i can't really help you anymore on that front.  Best bet is to just bruteforce it. 

I will split half of the entire wallet balance (~3.11 BTC amongst two addresses--1.5 BTC/$6300 reward!!!) to whoever solves it.  I think that $6k is a big enough bounty for people to throw real power at it.  If you manage to find the password, I'm happy to use a middleman to mediate the transfer.  At this point any bitcoin is better than none.  Good luck all, i can't think of anything else that could be helpful

thank you, i'll give a try but my hardware seems slow.
To be secure i've set-up properly the software, can you create another (empty) wallet on bitcoin-core and encrypt it with a very simple password like "123" or similar? So i'll crack it to see if the cracking software is working right

I´m constantly having segmentation fault errors when trying to use a wordlist of just 1mb (not even thinking about using crackstation one that´s over 4gbs). I cropped the list removing every non-alphanumerical password, converted from utf8 to ascii or added the --utf8 when running, etc.

Has anyone had success using large wordlists / tokenlists?

I´m running btcrecover under Ubuntu 14.04 with 6 x RX 570s. It works smoothly with small tokenlists over 20kp´s.

Butense, can you give any information regarding on how you usually generate passwords? At least in private? This would help reducing enormously the passwords space.

I tried many variation of the passwords in the first page, but they didn't worked.
Brute force is useless, it takes too many time also for very short passwords

Good try. You can use the mkey with btcrecover as outlined above.

Also, does anyone have any time approximations for bruteforcing according to password length? Such as

5 char = xx min
6 char = xx min
7 char = xx min
and so on.  doesnt have to be exact in any sense im just trying to wrap my mind around how long it would take (assuming gpu acceleration)

For a case sensitive alphanumeric password (a–z, A–Z, 0–9), using a GPU cracking setup at around 20k pwds/second, it will take:

Length   Time (days)
5      0,5
6      33
7      2038
8      126354

So very difficult without some dictionary guessing.

Here is the information for the address

   {
            "addr": "12KGAcU47BhCSQJCN9r2dHAvhDALMVsJkk",
            "balance": "15508294",
            "compressed": true,
            "encrypted_privkey": "f912462631805fb602ad6ce5763d6394f25d6374e71a55be1dfe3948bc1f483a256685238ce6459 7ff0afe69b03a8183",
            "label": "Slush",

            "reserve": 0
        },

EDIT: Was told that this information is necessary, so here you go

    "mkey": {
        "encrypted_key": "3ce2900d6c2df58a1cfa9ea1755a1599e0b60001fcd29d730c298de7538e3a0709e4fdb738d8ac6 1b5b03c582d724214",
        "nDerivationIterations": 80062,
        "nDerivationMethod": 0,
        "nID": 1,
        "otherParams": "",
        "salt": "d07e66c2606ae4fc"
    },


There is also another address within the wallet that has 3 btc that i am hoping to recover.  I will give the person who produces the successful password 0.5 in addition to the address above, but I guess youll have to trust me on following through.  

Crack this wallet and feel free to take the money, but please message me the password! Or post it here

I forgot the password i used back in 2013 and im dying to figure it out so i can take funds from the other addresses in the wallet.  I really don't remember anything about the password but it wasnt very long

Also, does anyone have any time approximations for bruteforcing according to password length? Such as

5 char = xx min
6 char = xx min
7 char = xx min
and so on.  doesnt have to be exact in any sense im just trying to wrap my mind around how long it would take (assuming gpu acceleration)


Mods, if this is in the wrong subforum feel free to move it!

Here coindesk featured an article on him, I believe his name is Dave and runs a wallet recovery service for cases much like yourself: https://walletrecoveryservices.com/

Goodluck and let me know if this was any help to you!

At least read the first page of this tiny thread before posting.

Even for a million dollars it's not possible to bruteforce your password if it's uppercase/lowercase/numbers and 15 chars long without ANY information about the password contents.
It's not MD5 or SHA, the amount of iterations makes bruteforce extremely slow.
How is it possible to not remember anything about pwd you used? Try hypnosis Cheesy

Did you used this wallet multiple times? If not, have you tried all possible refuses?
Like "fromwge" instead of "fromage"... some people tend to repeat the same refuses when they tipe passwords

Stupid question, but how do I use the information provided by OP to get started? Where can I import this encrypted private key in that format?

I'm not trying to bruteforce it, but I think based on the provided passwords I may have a hunch.

I have 5.54 bitcoin in one 33 character address from 2010, the wallet.dat file had been created with bitcoin-0.3.14-win32-setup.exe. I have a similar problem trying to find my private key from the "encrypted key", the wallet.dat file was overwritten, so I scanned drive with pywallet and it gives me the "encrypted key" string. How does one convert the encrypted key to the bitcoin format? Thanks for any help.

Thanks for replies. Have just now installed btcrecover and will run it, but wanted to know what will convert the encrypted password to WIF format.
as in the original example in this thread.
 "addr": "12KGAcU47BhCSQJCN9r2dHAvhDALMVsJkk",
            "balance": "15508294",
            "compressed": true,
            "encrypted_privkey": "f912462631805fb602ad6ce5763d6394f25d6374e71a55be1dfe3948bc1f483a256685238ce6459 7ff0afe69b03a8183",

            "reserve": 0
How does one convert this "encrypted_privkey" to wallet import format? If one had the key how to deal with the encrypted key? Thanks.

You need to read the instructions, it's very well explained there. Not only that, but you are missing some more information.

Check the OP again, and the next few posts after that one.

I can help you to restore/recover your wallet or password.

OK, did more reading, although I don't have a complete grasp of this.  I ran
C:\btcrecover-master\extract-scripts>extract-bitcoincore-mkey.py c:\btcrecover-m
aster\wallet.dat
Partial Bitcoin Core encrypted master key, salt, iter_count, and crc in base64:
YmxxxxxxqaVIxxxxxxxx6PjjUxxxxxxh/Jaxxxxxx8x/GCitxxxxxxxxDxxxxxxx21

and got above long string
then ran:
C:\btcrecover-master>btcrecover.py --data-extract --passwordlist
Starting btcrecover 0.17.9 on Python 2.7.13 32-bit, 16-bit unicodes, 32-bit ints

Please enter the data from the extract script
> YmxxxxxxqaVIxxxxxxxx6PjjUxxxxxxh/Jaxxxxxx8x/GCitxxxxxxxxDxxxxxxx21
Please enter your password guesses, one per line (with no extra spaces)
Use exit() or Ctrl-Z plus Return to exit
password1
password2
password3

exit
Wallet difficulty: 61,696 SHA-512 iterations
Using 1 worker thread
5 of 7 [#################################--------------] 0:00:09, ETA:  0:00:03
Password found: 'xxxxxxxxxxxxxxxxxxxxxx'

How do I get the private key out of the script?  More reading ? Smiley Thanks for all your help.
Tried pywallet --dumpwallet on it again but was no help.
I think I have the answer bitcoin-tool ... but having trouble compiling it.
