Date: Mon, 19 Dec 2011 00:40:25 +0400 From: Solar Designer <solar@...nwall.com> To: announce@...ts.openwall.com, john-users@...ts.openwall.com Subject: [openwall-announce] John the Ripper 1.7.9-jumbo-5; 1.7.9 for Windows re-release Hi, There's finally a -jumbo based on 1.7.9. The latest is currently 1.7.9-jumbo-5. (-jumbo-1 through -jumbo-4 existed for some hours only.) Available at the usual places are 1.7.9-jumbo-5 tarballs, as well as a binary build for Windows, including with OpenMP support. I've also re-released the Windows build of plain 1.7.9 correcting an issue in cygwin1.dll that affected external mode runs (and maybe more) with john-omp.exe (the re-release is john179w2.zip - with the "2"). Please download these at: http://www.openwall.com/john/ Here's a summary of changes in 1.7.9-jumbo-5 made since 1.7.8-jumbo-8: * -jumbo has been rebased on 1.7.9, thereby including the enhancements made in the main tree since 1.7.8. (magnum) http://www.openwall.com/lists/john-users/2011/11/23/2 * Support for cracking of RADIUS shared secrets has been added. (Didier ARENZANA, JimF) http://openwall.info/wiki/john/Using-john-to-crack-RADIUS-shared-secrets (currently these instructions are for Didier's original contribution, not updated for 1.7.9-jumbo-5 specifically yet) * Raw SHA (SHA-0) support has been added. (magnum) * MSSQL (old and 2005) and MySQL (SHA-1 based) hashes computation has been optimized (these are 3 times faster on linux-x86-64i now). (magnum) * Lotus5 hash computation has been optimized, and optional OpenMP parallelization has been added for it (now 12 times faster on an 8-core linux-x86-64 machine). (Solar) * x86-64 builds now make use of SSE2 intrinsics for more of the hash and cipher types. (magnum, JimF) * More i-suffixed make targets have been added (which use an icc-generated assembly file for SSE2 intrinsics), including for 32-bit x86 builds (previously, this was only available for x86-64). (magnum, JimF) * MD4 implementation in hand-written assembly for x86/SSE2 and MMX has been added. (Bartavelle, magnum, JimF) * Assorted changes to dynamic formats (previously known as "generic MD5") have been made. (JimF) * The "pix-md5" format has been converted to be a wrapper of "$dynamic_19$", which used much faster code. (JimF) * An alternate implementation of NTLM hashing has been added (--format=nt2), using Bartavelle's SSE2 intrinsics instead of Alain's explicit assembly code. (magnum) * The NSLDAPS and OPENLDAPS formats have been obsoleted in favor of the salted-sha1 format. (magnum) http://www.openwall.com/lists/john-dev/2011/11/15/1 * A binary build of 1.7.9-jumbo-5 for Windows (including with OpenMP) has been made. (Solar) There's a known reliability regression with HMAC-MD5, and known reported-performance regressions with NTLM and CRC-32. For HMAC-MD5, you may want to use 1.7.8-jumbo-8 for now. For NTLM there's probably no actual slowdown, but you may try --format=nt2 and see if that is faster (on some systems/builds, it should actually be faster). For CRC-32, performance does not actually matter. Overall, this new version is faster. Non-OpenMP on E5420 (using one CPU core only), "make linux-x86-64i", 1.7.8-jumbo-8 to 1.7.9-jumbo-5: Number of benchmarks: 153 Minimum: 0.81602 real, 0.81602 virtual Maximum: 6.70472 real, 6.63777 virtual Median: 1.00484 real, 1.00384 virtual Median absolute deviation: 0.01990 real, 0.02303 virtual Geometric mean: 1.10899 real, 1.10841 virtual Geometric standard deviation: 1.33332 real, 1.33278 virtual The 18% slowdown is for CRC-32, which does not matter, whereas there's also a 6.7x speedup. The geometric mean suggests an 11% overall speedup. Same machine (2xE5420), same make target, OpenMP enabled: Number of benchmarks: 153 Minimum: 0.79342 real, 0.56158 virtual Maximum: 12.03732 real, 8.47542 virtual Median: 1.00202 real, 1.00271 virtual Median absolute deviation: 0.01500 real, 0.01710 virtual Geometric mean: 1.16469 real, 1.06979 virtual Geometric standard deviation: 1.57763 real, 1.35698 virtual The worst slowdown of 20% is again for CRC-32, whereas the best speedup is now 12x, for Lotus5. The geometric mean suggests a 16% overall speedup. (A few benchmark results were excluded from the comparison because of format name and other changes. 1.7.8-jumbo-8 actually reports 160 individual results and 1.7.9-jumbo-5 reports 162, but only 153 of those could be directly compared.) Enjoy, and please provide your feedback on john-users. Alexander
