User Reviews

  • Yes, this product works fine for short password. But for long password.... 14 chars password took me 3 days to crack. It spends a lot of time for long password. Finally, I found Renee PassNow, it is easy to use and reset the password in seconds.
  • Почему нельзя загрузить изображение? Разработчик не отвечает :) . Загружаю через QEMU всё загружается (графический интерфейс), но при загрузке через комп выдаёт текстовый режим. Как с ним работать , что вводить?
  • The name of this beautiful piece of hand-crafted, Hackish software is as famous as its outstanding history and developers. Thank you for continuing work on this essential tool for us. It's beautifully written and developed and easy to use. =) I've always had a copy of this little gem installed no matter the OS, no matter what machine I'm using, since at least the mid-'90s or whenever I first read about it and glimpsed its masterstroke code.

  • Downloaded the ISO-File and burned it to CD. Booted the PC with that CD. Ophcrack did its thing and then booted itself into a window. After 25 minutes it showed me all accounts an their passwords. Quite simple. Thanks. PS: I didn't rate the support, because I didn't need it.
