bruteforce-wallet

bruteforce-wallet is designed to find the password of an encrypted wallet file by either generating all possible passwords from a specified charset or using a dictionary file with one password per line. It supports encrypted wallets from Peercoin, Bitcoin, Litecoin, and similar cryptocurrencies.

The tool operates in two primary modes: exhaustive mode, which is useful when partial password knowledge exists (e.g., beginning, end, or length constraints), and dictionary mode for trying passwords from a file. Features include multi-threading for faster cracking, progress reporting via USR1 signal, and customizable character sets based on the current locale.

This package is particularly helpful for recovering access to wallet.dat files when passwords are forgotten but some details are remembered, though exhaustive cracking of strong, unknown passwords is computationally infeasible.

In exhaustive mode, bruteforce-wallet systematically generates and tests passwords within specified constraints (minimum/maximum length, prefix, suffix, charset) against one encrypted address in the wallet to decrypt it. Dictionary mode reads passwords line-by-line from a file and attempts each one. Multi-threading accelerates the process, and a USR1 signal triggers progress output to stderr without halting execution. The tool targets the wallet.dat format used by various cryptocurrencies.
