John the Ripper Pro password cracker for Linux

John the Ripper Pro password cracker for Linux 1.7.3

John the Ripper is a fast password cracker, currently available for many flavors of Unix, Windows, DOS, BeOS, and OpenVMS. Its primary purpose is to detect weak Unix passwords, although Windows LM hashes and a number of other password hash types are supported as well.

On Linux, the features currently specific to Pro versions are:

* Pre-built and well-tested native package (RPM), which may be installed with a single command - no need to compile

* Automatic detection of processor architecture extensions such as SSE2 and MMX for much faster processing, with transparent fallback on older CPUs

Also included is a pre-built RPM package for 64-bit capable systems, which makes use of 64-bit mode extended SSE2 (new in 1.7.3 Pro)

* A large multilingual wordlist optimized specifically for use with John the Ripper (4, 106, 923 entries, 43 MB uncompressed) is included in the package, and John the Ripper is pre-configured for its use

* Official support for Windows NTLM (MD4-based) and Mac OS X 10.4+ salted SHA-1 hashes (new in 1.7.3 Pro), in addition to all hash types supported by the free version (please see below for a full list)

* The included documentation is revised to be specific for the given package on Linux rather than generic, making it easier to understand

* As a bonus, the full source code sufficient to rebuild the package is also provided (can be downloaded separately)
