is a utility tool used to extract hash data from a Bitcoin wallet file (specifically wallet.dat ). Its primary purpose is to prepare a Bitcoin Core wallet for password cracking. By isolating the cryptographic hash and salt from the wallet file, it allows security researchers and penetration testers to use tools like John the Ripper or Hashcat to recover lost passwords or audit wallet security.
If you forgot the password, you must guess millions of passwords, hash them, and compare them. This is "cracking." But John the Ripper cannot read a .dat file directly. It needs a text string. provides that text string. Bitcoin2john
