So... I spontaneously forgot parts of my passphrase to my bitwarden vault which sucks. As I believe to remember most parts of it I hacked up a cracker, hoping against hope, to find the lost parts and gain my vault back.

I hope this is going to work.

How to use it

You need the stored keyHash for the target vault which can be found e.g. in %APPDATA%\Roaming\Bitwarden\data.json

example

user@system:~$ python3 bw_brute.py -e foo@domain.tld -w wordlist.txt -k keyHash

full help

user@system:~$ python3 bw_brute.py -h
usage: bw_brute.py [-h] [-j WORKERS] -e EMAIL -w WORDLIST -k KEYHASH

  -h           show this help message
  -j WORKERS   workers to start
  -e EMAIL     email address
