John the Ripper v1.7.9 Released
John the Ripper is free and Open Source software, distributed primarily in source code form. If you would rather use a commercial product tailored for your specific operating system, please consider John the Ripper Pro, which is distributed primarily in the form of “native” packages for the target operating systems and in general is meant to be easier to install and use while delivering optimal performance.
- 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.
