FCrackZip-Free Zip Password Cracker for Windows and Linux


FCrackZip is linux version Free/Fast Zip password cracker/recovery tool.  it also has a windows compiled version supplied by RubyPDF.

Features,

  • FREE
  • It doesn’t cost anything, it will run on many architectures, and the source is freely available, so you can customise it to your needs. If you make improvements, don’t hesitate to mail them to me, and I will include them in fcrackzip!
    One goal of fcrackzip was to provide a free but still fast zipcracker, so that other people can improve and contribute it further, in an open developement style.
    Other programs, like fzc, come not only without source, but the executable is even encrypted, so improving it or customizing it is difficult at best. (Maybe the programmers of other crackers don’t want that people see how crappy their code actually is? Nobody knows for sure, but I see no other reason for this strange, but common, behaviour)

  • FAST
  • On my old machine (a pentium-90), the portable C version is 12% slower than fzc, the fastest cracker I could find. Small parts of fcrackzip have been converted to x86 assembly, so it performs a bit faster (around 4%) than fzc now, on the same hardware (note: this is highly os/compiler dependent). Since the author of fzc claims that it is written fully in assembler, further improvements might well be possible. Incidently, on my new P-II machine, fcrackzip is almost twice as fast as fzc ;)

  • PORTABLE
  • fcrackzip was written in ISO-C, and should run on most platforms, even 64 bit ones (maybe after some tweaking). I’ll be glad to hear about portability problems so I can fix them.

  • FEATUREFUL
  • fcrackzip will, at some later stage at least, support many more useful operation modes than other crackers. It already supports multiple zip files with multiple files. Remember that the code is only a few hours old!
    However, since version 0.2.0 fcrackzip also includes a mode to brute force cpmask’ed images, something no other program (that I know of) can do, so at least there is one feature other crackers don’t have.And you can always implement your own modes.
