brute_force_bip38

C++ implementation of the brute-force decoder of BIP38 encrypted private keys written by countzero/brute_force_bip38.

Build

./scripts/build.sh

Configuration

1. Edit the config.txt with the publicAddressHex (in hex format) and the encryptedPrivateKey (BIP38 encoded private key) you know.
2. Edit the secrets.txt file with all secrets you want to test.

Start

./build/brute_force_bip38

The application will now utilize all available CPUs to test each secret against your BIP38 encoded private key. If a valid secret has been found it will be logged out to valid_secret.txt.
