Bitslice DES implementation supporting more SIMD instruction sets than before (in addition to our prior support of MMX through AVX and XOP on x86(-64), NEON on 32-bit ARM, and AltiVec on POWER):.

Benchmark using all-different candidate passwords of length 7 by default (except for a few formats where the length is different - e.g., WPA's is 8 as that's the shortest valid), which resembles actual cracking and hashcat benchmarks closer.

These include avoidance of unnecessary parsing (some of which creeped into the loader in prior jumbo versions), use of larger hash tables, optional use of SSE prefetch instructions on groups of many hash table lookups instead of doing the lookups one by one, and data layout changes to improve locality of reference.

Optimizations for faster handling of large password hash files (such as with tens or hundreds million hashes), including loading, cracking, and '-show'.

Updated to 1.9.0 core, which brought the following relevant major changes:.

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. John the Ripper is free and Open Source software, distributed primarily in source code form. Besides several crypt(3) password hash types most commonly found on various Unix systems, supported out of the box are Windows LM hashes, plus lots of other hashes and ciphers in the community-enhanced version.

The license has been relaxed.Its primary purpose is to detect weak Unix passwords. The formats interface has been made more GPU-friendly. Reconstruction of ASCII encodings of LM hashes has been implemented to save RAM. Cracking of bcrypt on 32-bit x86 with GCC 4.2+ and DES-based tripcodes has been sped up. Bitmaps have been implemented for faster comparison of computed vs. Trivial parallel and distributed processing has been implemented with new -fork and -node options. More speed metrics have been added to the status line. Changes: Incremental mode's efficiency has been improved, and its length and character set limitations in default builds have been lifted. On top of this, many other hash types are added with contributed patches, and some are added in John the Ripper Pro. It supports several crypt(3) password hash types commonly found on Unix systems, as well as Windows LM hashes. Its primary purpose is to detect weak Unix passwords. John the Ripper is a fast password cracker, currently available for many flavors of Unix, Windows, DOS, BeOS, and OpenVMS.
