: The simplest starting point is a dictionary attack using a wordlist like rockyou.txt . Replace /path/to/wordlist.txt with the path to your wordlist.
Open the wallet.hash file in a plain text editor (e.g., Notepad++). Remove anything that is not the hash itself — often the script may print console information or file names that will cause hashcat to fail. The file should contain exactly one line : the hash string beginning with $bitcoin$ .
: If you are using the bitcoin2john.py script as described, it will produce a hash compatible with Hashcat mode 11300 . You can verify your hash's format against the official Hashcat example hash: extract hash from walletdat top
Move your copied wallet.dat file into this same folder for easy access. Step 2: Run the Extraction Script
John the Ripper handles these hashes natively. You can run a basic dictionary attack using: john wallet_hash.txt --wordlist=passwords.txt Use code with caution. Option B: Hashcat (Recommended for Speed) : The simplest starting point is a dictionary
Install the required Python Berkeley DB library:
sudo apt-get update sudo apt-get install python3 python3-pip python3-bsddb3 # Ubuntu/Debian Use code with caution. 📥 Step 2: Download the Extraction Script Remove anything that is not the hash itself
To extract a password hash from a wallet.dat file for recovery purposes, the standard industry practice is to use the bitcoin2john.py script. This script converts the wallet's encrypted binary data into a format that password-cracking tools like Hashcat and John the Ripper can process.
