![]() You will also need to download the hashcat program. Sudo dnf install libdb-devel python3-devel (maybe with “sudo”, depending on your setup).įor the command above to work you also need to have Berkeley DB itself The script to work with Python 3 you need to install the corresponding module: – Since Python 3 no longer provides Berkeley DB support out of the box, to get – The bitcoin2john.py script is compatible with both Python 2 and Python 3. – This procedure also works with many altcoins historically forked from Bitcoin. Run john on the output of the bitcoin2john.py script.ģ. Run bitcoin2john.py on Bitcoin or some altcoin wallet file(s).Į.g./run/bitcoin2john.py wallet.dat > hashesĢ. To quote Bitcoin2john creators Openwall…ġ. In particular, you must already have a compatible version of Berkeley DB installed, because wallet.dat files are actually Berkeley DB files. John The Ripper needs some extra work to be able to crack wallet.dat files. Hashcat is a more modern cracker that supports NVIDIA CUDA, has a higher performance than Bitcoin2john, and natively supports cracking Bitcoin wallet.dat files.It does not natively support wallet.dat files (some dependencies need to be installed). John The Ripper is the classic program that can crack passwords via OpenCL GPU language and Intel AVX, AVX2, and AVX512 instruction sets.Choosing Your Weapon Of ChoiceĪs we mentioned above, the two programs you can use for brute forcing Bitcoin wallet.dat password hashes are John The Ripper and Hashcat. ![]() Nevertheless, Bitcoin2john does support Python 3. For a long time, Pywallet was based on Python 2, and Bitcoin2john code was actually forked from it. ![]() The reason is to avoid the Berkeley DB dependency installation process when you run Bitcoin2john on Python 3. It is recommended (but not required) to have Python 2 installed to run Bitcoin2john. Or just copy and paste the file from Github:.run/bitcoin2john.py (If you are on Windows then install Git for Windows first to get git) Run git clone, and the Bitcoin2john script will be available under the path.Obviously, you must also have Bitcoin2john on your computer, which you can get in one of two ways: It also works with some wallet.dat files of altcoins derived from Bitcoin (e.g. Bitcoin2john prerequisitesįirst of all, because Bitcoin2john only works with Bitcoin Core wallet.dat files, this is the file from a you must have. It is a more advanced alternative to John The Ripper. But in the case of Bitcoin wallets, Hashcat is the tool of choice. Usually, the program used for hash recovery is John The Ripper (hence why it’s called Bitcoin2john). When it extracts the hash, then you use a hash recovery tool to recover the lost passwords. Where to get the Bitcoin2john script from?īitcoin2john is a small Python script that extracts the hash out of Bitcoin core wallet.dat file. You can learn here how easily you can recover your wallet password through this simple program. To most people, those wallets are inaccessible, but there is still a chance that we may recover those wallets using a program named Bitcoin2john. This could be because we have forgotten their passwords. We may have old wallet.dat files which we are unable to access or recover funds from.
