PW recovery: fcrackzip. -p switch won't work

sinnerman · 04-23-2005, 10:22 PM

I'm running a brute force fcrackzip on a file on a linux box. I have
to stop the process and when I start it again, I don't want to have to
start over from the beginning of the alphabet. According to the man page there's a -p
switch that is supposed to specify the beginning string, but it doesn't
seem to work.
if I remember correctly the command I ran (I know it doesn't include the -p) is:

Code:

<mylinuxbox@localhost>$fcrackzip -v -c a1! -l 7 documents.zip

Anyone have a detailed example (command line code) on
how to get fcrackzip to start on something other than "a". thanks

when you stop fcrackzip it should generate a log file.........and the log should tell you what letters/numbers the process stopped at........so, when you restart you just use the -p switch and include the letters that were last processed according to that log.........IE

Code:

 mylinuxbox@localhost>$fcrackzip -v -c a1! -p billyjo -l 7 documents.zip

freakyg - thanks for the reply. I'll try it when I actually have to stop the prog. I didn't know it output a log file...my confusion was coming in with the fact that even though I was using the -l switch (when I tried to restart say at "n" or "s"), the -p character number wasn't increasing.

Quote:

The starting password given by the -p switch determines the length. fcrackzip will not currently increase the password length automatically, unless the -l switch is used.

cheers,
