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.
