John the Ripper Linux Password Cracker
This module uses John the Ripper to identify weak passwords that have been acquired from unshadowed passwd files from Unix systems. The module will only crack MD5 and DES implementations by default. Set Crypt to true to also try to crack Blowfish and SHA implementations. Warning: This is much slower.
