Installing

Download the standalone jar or

Build from Source

• git clone https://github.com/isentropy/ethcracker.git
• cd ethcracker
• mvn package

The compiled jar will be in the 'target' dir.

Running

You can use the included wrapper script: ./ethcrack.sh [wallet file] [passwords file]

or run with java: java -jar ethcracker-0.1.jar [OPTIONS]

Options

• --wallet [FILE] : the wallet file to crack [required]
• --pwfile [FILE] : newline separted list of passwords to try [optional, uses stdin if absent]
• --out [FILE] : a file to write the password, if found [optional]
• --threads [N] : # consumer threads [optional, chosen automatically as 2*num_cpu_cores]

Checking Results

The discovered password is written to stdout as "FOUND PASSWORD: ...", but consider using the --out option, which outputs it to a file automatically.

Ethcracker exits with retcode 0 if it found the password and 1 if it ran without error but didn't find password. Other return codes indicate an error.
