Output for: btcrecover hashcat John the Ripper

btcrecover wants a token list; hashcat and John the Ripper want a flat wordlist (one candidate per line). Pick your tool and the output formats itself.

How long will testing take?

Pick the wallet format and hardware you will test on — the estimate uses the measured speeds from the benchmarks page. It updates every time you generate a list.

Wallet format

Hardware: Ryzen 9 9950X CPU RTX 5090 GPU i7-10700K CPU

Generate a list to see the estimate.

Keep it safe: The generated file is your candidate list — store it offline with your wallet files and never upload it to a public checker or unknown website. Fragments and variations are fine; a full password or a seed phrase never belongs in any tool or website.
