brute-force-cryptowallet

• This is a tool for those of you who've somehow lost your Ethereum wallet password.

• It's essentially a stripped-down version of pyethsaletool. In addition you can have passwords be read from a newline-delimited file, and/or provide a specification to be used to generate passwords. The multiprocessing library joblib is used to test out passwords using all the cores on your machine.

• This tool is compatible with both Python 2 and Python 3. It depends on the following libraries

Example1

Let's say you have a wallet file named ethereum-wallet.json protected by the password correct horse battery staple. You enter your guesses into a file named passwords.txt, like so:

shelly sells seashells down by the seashore
It was the best time of times, it was the worst of times...
Password1
correct horse battery staple
mean mr mustard sleeps in the park

If you run the utility like so...

./pyethrecover.py -w ethereum-wallet.json -f passwords.txt

...you should get back something like this:

shelly sells seashells down by the seashore
It was the best time of times, it was the worst of times...
Password1
correct horse battery staple

Your seed is:
abc123abc123...

Your password is:
correct horse battery staple

Example2

Let's say you have a wallet file named ethereum-wallet.json and you remember that you password is a greeting in some language followed by the name of an american president. Say you're not sure if the president is addressed with a title, but if he is you're certain it's either "president" or "mister". You would create a file password_spec.txt like so ...

[
    ('hello', 'bonjour', 'hola'),
    ('', 'mister', 'president'),
    ('smith', 'jefferson')
]

and call it like so...

./pyethrecover.py -w ethereum-wallet.json -s password_spec.txt
