# GRIDCRACK v20140822 by 1N3 @ http://xerosecurity.com
#
# USAGE: ./gridcrack <crack/status/setup> <format>
#
# ABOUT:
# GRIDCRACK is a Linux grid based password cracker used to leverage multiple servers to crack a single hash file.
#
# REQUIREMENTS:
# 1) Two or more Linux based servers running John The Ripper (john)
# 2) root SSH keys setup for automatic login/authentication via SSH keys
# 3) A large masterlist dictionary file to split amongst the configured nodes
#
# HOW IT WORKS:
# Running ./gridcrack setup will launch the initial setup of gridcrack which will prompt for the masterlist.dic file (a large wordlist of your choice..).
# From there, it will proceed to split the file into equal parts based on the number of configured nodes in this script (NUM_NODES). Next, It will transfer
# the individual parts of the split wordlist to each host via SCP. From here, the user can copy/paste their hashes into the hashes.txt (/pentest/gridcrack/hashes.txt)
# and run the appropriate command to begin the brute force attack (ie. ./gridcrack crack NT). From here, gridcrack will first copy the hashes.txt to each node first,
# then proceed to run john on each node simultaneously using the format specified (ie. NT). Results are then displayed back to the central server as
# each node finishes. A status mode is also included to show the status of john on each node (ie. ./gridcrack status NT).
