Bitslice DES S-box expressions using AVX-512's "ternary logic" (actually, 3-input LUT) instructions (the _mm512_ternarylogic_epi32() intrinsic).On x86(-64): AVX2, AVX-512 (including for second generation Xeon Phi), and MIC (for first generation Xeon Phi).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. Its primary purpose is to detect weak Unix passwords.
