Name        : john

Summary     : John the Ripper password cracker
Description :
John the Ripper is a fast password cracker. Its primary purpose is to
detect weak Unix passwords, but a number of other hash types are
supported as well.

Update Information:

* Added optional parallelization of the MD5-based crypt(3) code with OpenMP.
* Added optional parallelization of the bitslice DES code with OpenMP.
* Replaced the bitslice DES key setup algorithm with a faster one, which
significantly improves performance at LM hashes, as well as at DES-based
crypt(3) hashes when there's just one salt (or very few salts).
* Optimized the DES S-box x86-64 (16-register SSE2) assembly code.
* Added support for 10-character DES-based tripcodes (not optimized yet).
* Added support for the "$2y$" prefix of bcrypt hashes.
* Added two more hash table sizes (16M and 128M entries) for faster
processing of very large numbers of hashes per salt (over 1M).
* Added two pre-defined external mode variables: "abort" and "status",
which let an external mode request the current cracking session to be
aborted or the status line to be displayed, respectively.
* Made some minor optimizations to external mode function calls and
virtual machine implementation.
* The "--make-charset" option now uses floating-point rather than 64-bit
integer operations, which allows for larger CHARSET_* settings in params.h.
* Added runtime detection of Intel AVX and AMD XOP instruction set
extensions, with optional fallback to an alternate program binary.
* In OpenMP-enabled builds, added support for fallback to a non-OpenMP
build when the requested thread count is 1.
* Added relbench, a Perl script to compare two "john --test" benchmark
runs, such as for different machines, "make" targets, C compilers,
optimization options, or/and versions of John the Ripper.
* Additional public lists of "top N passwords" have been merged into the
bundled common passwords list, and some insufficiently common passwords
were removed from the list.
* Many minor enhancements and a few bug fixes were made.
