Bitcoin2John is a vital tool in the cryptocurrency security ecosystem. While it poses a risk to wallets protected by weak passwords, it serves as the primary mechanism for legitimate password recovery. Its existence underscores the critical importance of using strong, unique passphrases for Bitcoin Core wallets. A modern RTX 4090 GPU can test roughly
