* Package name : libzc Version : 0.3.0 Upstream Author : Marc Ferland <marc.ferl...@gmail.com> * URL : https://github.com/mferland/libzc * License : GPL-3.0 Programming Lang: C Description : Fast, portable and high-quality zip cracking library featuring bruteforce, dictionary and plaintext attack modes. libzc is a fast, portable and high-quality zip breaking library. It targets exclusively the earlier PKZIP-2.0 cipher (just like fcrackzip, and pkcrack). It is entirely written in C (no assembly language, so very portable) and has very little dependencies. Currently, only zlib and libcheck (for unit tests) are required to build it. The bruteforce algorithm uses threads to scale with the number of cores available (unlike fcrackzip) and is written in a way that is easily vectorizable by modern compilers. The library also implements the full plaintext attack described by the Biham & Kocher paper (like pkcrack). Last, a simple dictionary attack is also offered. As an added bonus, a command line client (yazc, Yet Another Zip Cracker) also comes bundled with the library. So in conclusion, it compares to both fcrackzip and pkcrack, only faster, cleaner and more portable. Benchmark using the zip file from fcrackzip (cpu is an Intel Core i7@ 3GHz): $ time fcrackzip -b -ca -u noradi.zip real 0m18.011s user 0m17.972s sys 0m0.008s $ time yazc bruteforce -t8 -a noradi.zip real 0m1.962s user 0m15.440s sys 0m0.012s libzc was 9x faster in this test than fcrackzip. I've never packaged anything for Debian so I need a sponsor to get this uploaded. Regards, Marc
