>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

>user	0m17.972s

>$ 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
