0.50 BTC reward for a valid password.

[WOW777]

Hello. I’ve been trying to open my wallet 1GRth6rP4uaPXdw2T6HcGmi7f1RzW4xV94 for almost a year now. I know the password characters, I also have a saved password that is inappropriate.
According to the advice of the moderator https://bitcointalk.org/index.php?topic=5209037.msg53342672#msg53342672
I bought the software https://www.thegrideon.com/bitcoin-password-recovery.html#speed

Name:
Sergey Vintachenko
Key:
000017-XEXF24-RP0QH2-EB58KT-J6X0C1-CXPNZ4-JUY931-020ADE-4J893X-6TEYA4

This is not what you need and it didn’t work because it goes through all the letters and characters.
Now I want to try this tip https://bitcointalk.org/index.php?topic=5208559.msg53340427#msg53340427
I used bitcoin2john.py and got a hash string. When I try to start this, nothing happens.

Hi,


can you clarify a bit more, please? Do you have the wallet.dat file backed up somewhere? if not do you have any private keys backed up?

Hi,

I have a wallet.dat file and a text document with an invalid password.

[posi]

I didnt understand the language in the link you provided in the OP because it a Local thread but for you to get the required answer i will need you to answer some few questions.
What is the name of the wallet you lost it password?
Is the wallet.dat file in good condition?
Why the use of hashcat ( cause it was used in password hack) ?

[Csmiami]

Is the wallet truly yours, or did you buy it in a website to try to crack it?

If it's the latter, then it's almost impossible to crack it open, as many people are already on it, and you see the results they are having....

If the wallet is truly yours, and you know the lenght and "some" of the characters used, then there's a chance of cracking it

The wallet is called the Bitcoin core, I have the wallet.dat file and the wrong password, which does not work.
I was advised a hackcat for hacking. I suspect that a typo in the password is possible, and I want to check it on the processor.

My wallet is not bought. That's why I'm trying to access coins.

Why would you post the public key of the product that you've bought? Now people would just abuse it and get the product key deactivated. Remove it from the OP immediately.

The software is a python script and you'll need to install python first, together with its dependencies. If you don't want to deal with the hassle of setting everything up, extract the key and contact them[1].

What I understand until now is that you have transferred the bitcoins from Electrum to Bitcoin Core wallet back in 2013, with the screen shots you provided in the other threads and you don't have the password for the wallet for the Core.
I'll post the picutres here :
Electrum >



Bitcoin Core >



I hope this helps at least a little

Let the community use it, I do not mind, I paid $ 30 for it. The service wants a file.

I also restored 20GB text files hoping to find the keys, in one I found a password that says Bitcoin core, but the password is not accepted.

The service wants a file.

You can submit the hash only to the service. It does incur quite a hefty fee so it could be your last resort.

Since you roughly know the generally structure of the password with the characters, would it be a better idea for you to use a tailored program for this? BTCrecover is quite good for this[1].

[HCP]

Hashcat with appropriate rules would probably run faster than btcrecover.

In any case, I would highly recommend you contact https://walletrecoveryservices.com/ and negotiate a deal with them. They are specialists in this field and have had quite a bit of success. It's fairly safe as they only require the "password hash" extracted using bitcoin2john.py... they do not need your wallet.dat, so will not be able to access your coins.

The downside is that they can be quite expensive. However, it's likely to yield better results than someone who doesn't know what they're doing messing about with hashcat, btcrecover and various rulesets/token files

20% - 30 bitcoins is a lot of money to just give away.

[BitMaxz]

While it is very difficult, I use this program https://www.thegrideon.com/bitcoin-password-recovery.html

Honestly, I never heard the tool from thegrideon.com it seems a software that can brute-force the password of wallet.dat file.
Make sure to run this software on offline mode for your wallet safe.

Alternatively use BTCrecovery which is already mentioned above.

Why not watch a video on youtube how to use the BTCrecovery?

Here are some videos that you can follow
- Recover your lost Bitcoin password with btcrecover - Install Guide
- Recover your Bitcoin Core wallet password with btcrecovery

[HCP]

20% - 30 bitcoins is a lot of money to just give away.

Fair enough... but another way to look at it is that at the moment, you effectively have 0 bitcoins... which is better 0BTC or 120BTC?

When I try to start this, nothing happens.
How to run a hashcat on a processor?

Ok, so what do you mean by "nothing happens"?

To run hashcat, you need:

1. The password hash generated by the "bitcoin2john.py" script
2. Some idea of what your password is

Code:

hashcat.exe -m 11300 -a 3 <$bitcoin_hash_goes_here> <password mask goes here>

For example you can test using the example hash from here that has the password 'hashcat':

Code:

hashcat.exe -m 11300 -a 3 $bitcoin$96$d011a1b6a8d675b7a36d0cd2efaca32a9f8dc1d57d6d01a58399ea04e703e8bbb44899039326f7a00f171a7bbc854a54$16$1563277210780230$158555$96$628835426818227243334570448571536352510740823233055715845322741625407685873076027233865346542174$66$625882875480513751851333441623702852811440775888122046360561760525 hash?l?l?l

-m 11300 == bitcoin wallet.dat format
-a 3 == bruteforce attack mode (word lists probably are not of use to you if you think you have a good idea of what your password actually is)
hash?l?l?l == password mask of text 'hash'+lowercase letter+lowercase letter+lowercase letter

That command should "quickly" find that the password is: hashcat

$bitcoin$96$d011a1b6a8d675b7a36d0cd2efaca32a9f8dc1d57d6d01a58399ea04e703e8bbb44899039326f7a00f171a7bbc854a54$16$1563277210780230$158555$96$628835426818227243334570448571536352510740823233055715845322741625407685873076027233865346542174$66$625882875480513751851333441623702852811440775888122046360561760525:hashcat

Your issue will be defining the 'mask'... you need to know how many characters in your password, and the characters used... ie. lower case, uppercase, numbers, symbols etc, then you can build a mask using the following table:

- [ Built-in Charsets ] -

  ? | Charset
 ===+=========
  l | abcdefghijklmnopqrstuvwxyz
  u | ABCDEFGHIJKLMNOPQRSTUVWXYZ
  d | 0123456789
  h | 0123456789abcdef
  H | 0123456789ABCDEF
  s |  !"#$%&'()*+,-./:;<=>?@[\]^_`{|}~
  a | ?l?u?d?s
  b | 0x00 - 0xff

So, say you think your password is 8 chars long, and uses a mix of lower, UPPER, numbers and symbols... you would use: ?a?a?a?a?a?a?a?a

If you are 100% of the characters at a position, ie. you know 100% the password starts with WOW, you could use: WOW?a?a?a?a?a
or if you know it has 2 numbers on the end: ?a?a?a?a?a?a?d?d

Obviously, the more specific you can be with your mask, the smaller the keyspace that needs to be searched and the less time it will take to find.

Refer here for more info regarding mask attack: https://hashcat.net/wiki/doku.php?id=mask_attack


NOTE: if you find you are getting "Token Length Exception" errors when trying to run hashcat, try using the BETA version from here: https://hashcat.net/beta/

Thank you very much, I will try, but I'm not strong on the command line, I prefer the application GUI.

[Pmalek]

While it is very difficult, I use this program https://www.thegrideon.com/bitcoin-password-recovery.html

That software has been mentioned on this forum a few times in the past. The info I could find is that it is closed-source and personally I wouldn't use it when there are better alternatives, like BTCrecover. Be careful what you use for such amounts.

Does BTCrecover refuse to work like a hash cat when I enter the string hashcat.exe -m 11300 -a 3 $ bitcoin $ 96 $ **** hash? ~? #? 5? C? L? T E K? F? Y? /? 5? r? this does not work. Now I am downloading the blockchain and making a video so that it is clear what I am doing.

[HCP]

your string looks a bit incorrect... it shouldn't have all the spaces in it...

Code:

hashcat.exe -m 11300 -a 3 $bitcoin$96$**** hash?~?#?5?C?L?TEK?F?Y?/?5?r?

But it looks like you're getting the position of the ?'s wrong... and you don't quite get what the ?'s mean.

?l == lowercase letters (ie. abcdefghijklmnopqrstuvwxyz)
?u == uppercase letters (ie. ABCDEFGHIJKLMNOPQRSTUVWXYZ)
?d == numbers 1234567890
?s == symbols !"#$%&'()*+,-./:;<=>?@[\]^_`{|}~
?a == All of the above

if you want to use a specific letter... you don't use ? at all... So, I'm not sure exactly what you are trying to use as your mask... but pretty much none of your ?'s make any sense...

So, that command as it is written isn't going to work.

[LoyceV]

You've spent the Bitcoin Cash without moving the real Bitcoin on October 30, 2017. Any chance you still have the private key imported into a BCH wallet you have forgotten about?

20% - 30 bitcoins is a lot of money to just give away.

You might be able to negotiate on that amount

[seoincorporation]

Usually the command line scripts run under one core on the CPU, I think we could use crunch to generate the passwords by range and use the GNU parallel tool to find it faster.

I haven't tried yet, but i will make some experiments and share the results. This should make faster the HCP way.
