This repo contains a utility that helps you crack the 25th word of your seed phrase. You still need to know the first 24 words, and you also need a guess at the 25th word. Finally, you need either your c-chain or p-chain address to match against.
I haven't done any work on typos.py to validate how good it is. I stole it from this repo: https://github.com/alexbowe/bitcoin-passphrase-cracker
That repo is a bit out of date for the bip_utils library version, so I updated the
code and simplified it a little. I also added support for matching against p-chain
addresses.
I tested this with a sample seed and passphrase and it seems to work at least for small differences. I ran this with python3.9, but I think it should work with most py3 versions.
If you need to install python, follow these directions: https://linuxize.com/post/how-to-install-python-3-9-on-debian-10/
You'll also need to install the dependencies in requirements.txt:
pip3.9 install -r requirements.txt
You'll need to edit the contents of crack_key.py to contain the 24 words you know,
your best guess, and your p-chain address.
Finally, run the job using:
python3.9 crack_key.py
This could take a very long time to run. If your guess is bad, or you have the wrong 24 seed phrase words, it won't work at all.
Python is single threaded, but if you have multiple guesses, you can run them in parallel. Just copy/paste the script and make sure each includes the guess you want to try.
