John the Ripper is a fast password cracker, currently available for many flavors of Unix (11 are officially supported, not counting different architectures), Windows, DOS, BeOS, and OpenVMS. Its primary purpose is to detect weak Unix 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 is an updated version of Ryan Lim's patch for john the ripper to support MPI, in addition to a large number of third party patches to support additional ciphers and such.
MPI allows you to use multiple processors on a single system, or a cluster of systems for cracking passwords using john the ripper. Incredibly usefull in these days of multi core processors.
A compatible MPI implementation is required.
This has currently been tested on Linux/AMD64 and Linux/x86 using mpich2-1.0.2
Note: make generic seems faster on AMD64 than the actual amd64 make target, especially if your using gcc 3.4.
