  1. Hi,
    I tried to use fcrackzip before, but it took too much time. I wonder if it even worked properly and try to used it on zip file with password I know and it didn’t find it. Syntax I used was something like that:
    fcrackzip -b -c a1A -l 5-10 -v ZIP_FILE
    Now I hit this site and re-write my command and it starts to work, but I don’t know why. I just added -u switch to command, can you explain this?
    working syntax:
    fcrackzip -b -c a1A -l 5-10 -v -u ZIP_FILE

  2. the password is asd123 I create, after use fcrackzip in kali, it give me alv as password, then I try alv to open the zip file, it’s correct, why?
