Step 1. open your web browser
Step 2. Type www.google.com into the browser and press enter
Step 3. Type "john the ripper tutorial bitcoin" into the Google search box and press enter
Step 4. Read/Watch Tutorials

This one seems to cover it pretty thoroughly: http://www.gobitgo.com/articles/1005/How-To-Recover-Your-Bitcoin-Wallet-Password/

Seriously? Did you even look at the guide I linked to?  Huh  It has all the commands and pretty pictures...

NOTE: You appear to have skipped step 6.2 where you extract the hash from the wallet...

you need gpu acceleration if you have a strong password to crack. It goes very quickly in the 100's of billions of possibilities... https://github.com/gurnec/btcrecover

They've already attempted to use btcrecover... https://bitcointalk.org/index.php?topic=2007159.msg19982862#msg19982862

Given that they seem to struggle with following guides/instructions, editing text files and using the command line... I don't hold much hope for this user recovering their bitcoins without (a lot) of external help... Undecided

Jhon the ripper is a CPU cracking program, which makes it very slow. Cracking passwords is like mining, you are looking for a password that fits the hash value. GPUs are better at finding hashes so you should use them for password cracking as well. I find that a program called hashcat does the best job. If you are were ever using some computer for mining then I suggest you just install hashcat(the GPU version) on them and not on your kali linux installation and you will be good to go ( you should do this because I assume they will have the best GPUs and the necessary GPU drivers installed). Don't forget to run "hashcat --help" to find everything you need, you have many options: brute-force,dictionary attack, hybrid attacks,...Good luck

Jhon the ripper is asking 16 hours, 18 minutes & 10 seconds for 100000 passwords to try. It is too slow process.
Thanks for cooperation.

hacking bitcoin  wallet passwords ae gpu intensive, using cpu bruteforce cracking method is very slow. i also heard about hashcat tools that can crack bitcoin paper wallet but it was tested in a BIP38 bitcoin wallet . i don't have an ideaa if what kind of BIPxxx bitcoin wallet you are using.maybe this tools is BIPxxx specific.

Honestly, if you managed to get John The Ripper working... you should be able to follow the instructions here: https://github.com/gurnec/btcrecover/blob/master/docs/INSTALL.md to get btcrecover and the required modules like pycrypto etc installed and working.

It should be able to test passwords a lot faster than John The Ripper.

You seem to have already generated a potential password list... so you can use that with btcrecover: https://github.com/gurnec/btcrecover/blob/master/TUTORIAL.md#the-passwordlist

Entering passwords in Bitcoin Core in an automated fashion would be even slower that Jhon the Ripper, which is, as I said, a CPU program. I guess it is using 4 of your cores there, which is way too slow compared to hundreds of cores on your GPU. This is a job for GPU, go get yourself a hashcat program and don't waste your time on that outdated program.

PS: You don't need Kali for password cracking. That is where I learned about these password cracking programs as well, but it not a good system for the job. You need a GPU driver for that, don't waste your time on anything else, Kali doesn't have as much of support for the drivers as other Linux systems. You use Kali if you are having a whole operation, since it has all of the things already packed in. You don't use it for a single purpose, usually.

Are there any good guides out there?  I found one a few days ago, but can't find it now.

Sure, here is my guide for it:
Code:
1. Don't use Jack the ripper for password cracking
2. Use a program that utilizes GPU like hashcat
3. Use an option -m 11300 for cracking Bitcoin wallet.dat in hashcat
4. Other options depend on your situation

Excuse my dumb question, but.. did you even read this thread?

Short summary:
  • JackTheRipper = CPU cracking
  • Hashcat = GPU cracking
  • GPU waaaay faster than CPU

But, to be honestly.. if you need to ask such questions on this forum.. i don't think you are capable of "cracking a wallet".
May i ask whether you have forgotten your password (which makes it easier to crack your wallet file if you remember parts of your password)?
Or are you trying to "make money" with cracking wallets? In this case, you can pretty much forget that and should turn over to something which isn't pure waste of time.


And for the future: Please google first. This forum (especially this subforum) is related to Bitcoin. Its not a guide on how to crack wallets. Particularly not if you are trying to do blackhat-stuff.

I was able to setup btc recover, and was getting 1400 pass / secs, but hashcats seems to be better even if I didn't tried it.

everyone is capable of cracking anything with the proper software, hardware and time, no need to be a arrogant, anyone included the best of the best were all beginners at some point what they now master. So there is no reason for the poster not to be able to achieve anything he wants.

If cracking wallet.dat password isn't part of this forum, nothing is.

What kind of though police school did you went? the one where you decided the rules, what is to be said and not?

I generally like to think the best of people... Besides, all the info I gave was readily available using Google and spending a bit of time reading...

In fact, all the info in this thread is readily available if you actually put some effort into researching the topic.

Unfortunately, it seems the vast majority of people can't be arsed putting the effort in, or have watched too many Hollywood movies where you can type "hackpassword.exe supersecretfile.dat" (usually into a command prompt with 30pt font) and it takes 30 secs to crack! Roll Eyes Tongue

Well, besides all of these information being available on the internet (probably less than 5 minutes yahooing googling),
he can't do anything with these information without also having access to a wallet.dat.

And maybe he isn't even trying to steal peoples coins. And even if he is.. he obviously doesn't have the mental capabilities to perform such a task.

I'd like to illustrate that more detailed:
There is a green matrix-like font running from the top of the screen to the bottom.
And after 1000 lines output read by the highly professional hacker per second and hammering on the keyboard without even typing words, the 'password of satoshis address' appears.

Hackers are magicians. Didn't know that?

Probably thats the reason some non-techy persons think they can type a few words, look at a green screen, and get fkin richt instantly..
