Brainflayer : Brainflayer is a Proof-of-Concept brainwallet cracking tool that uses libsecp256k1 for pubkey generation. It was originally released as part of my DEFCON talk about cracking brainwallets (slides, video, why).

The name is a reference to Mind Flayers, a race of monsters from the Dungeons & Dragons role-playing game. They eat brains, psionically enslave people and look like lovecraftian horrors.

The current release is more than four times faster than the DEFCON release, and many features have been added.

If brainflayer is useful to you, please get in touch to let me know. I'm very interested in any research it's being used for, and I'm generally happy to collaborate with academic groups.

Usage:

Basic

Precompute the bloom filter:

hex2blf example.hex example.blf

Run Brainflayer against it:

brainflayer -v -b example.blf -i phraselist.txt

or

your_generator | brainflayer -v -b example.blf
