John the Ripper is a fast password cracker. Its primary purpose is to detect
|
|
|
|
|
weak passwords. Besides several crypt(3) password hash types most commonly
|
|
|
|
|
found on various Unix flavors, supported out of the box are Kerberos AFS and
|
|
|
|
|
Windows NT/2000/XP/2003 LM hashes, plus several more with contributed patches.

This script includes an option to apply the community-enhanced "Jumbo" patch,
|
|
|
|
|
which integrates lots of contributed patches adding support for over 40
|
|
|
|
|
additional hash and cipher types (including popular ones such as NTLM, raw MD5,
|
|
|
|
|
etc.), as well as some optimizations and features. Unfortunately, its overall
|
|
|
|
|
quality is lower than the official version's. To include the Jumbo patch,
|
|
|
|
|
simply pass JUMBO=1 to the build script:
|
|
|
|
|
JUMBO=1 sh john.SlackBuild
|
|
|
|
|
|
|
|
|
|
This script also includes an option to merge the /usr/share/dict/words
|
|
|
|
|
dictionary into the standard password list, which marginally improves results
|
|
|
|
|
compared with the default password list. To include this, simply pass
|
|
|
|
|
MERGEWORDS=1 to the build script:
|
|
|
|
|
MERGEWORDS=1 sh john.SlackBuild
|
|
|
|
|
|
|
|
|
|
The options can be used in combination as well:
|
|
|
|
|
JUMBO=1 MERGEWORDS=1 sh john.SlackBuild
|
|
|
|
|
|
|
|
|
|
