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 Ryan Lim's patch for JTR to support -MPI. MPI allows you to use multiple processors on a system or even a cluster -of systems for cracking passwords using JTR. If you decide to apply this, you -will also need openmpi installed. JTR's author does not recommend using the -patch, so use it at your own risk - for more information, see this link: - http://www.openwall.com/lists/john-users/2005/08/24/4 -This script also contains an optional "jumbo" patch, which enables processing -of many password hash types and ciphers that are not otherwise supported. - -Note this will not build in parallel; unset MAKEFLAGS if you have problems. +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.
