I also would like such an option (this could be attempted after trying what -w does now)

I just installed pdfcrack to try a few modifications of a password that's not working as it should, but although Evince and Inkscape tell me that the file is encrypted, pdfcrack tells me "Error: Encryption not detected".
Evince and Inkscape do say "weird encryption info".
I've looked for the "trailer" markers, and apparently there are none.
I've first tried...

I have been using version 0.8 with no success (probably I set the wrong set of characters or simply it's longer) so I downloaded version 0.11.
Right now on the very same file it tells me
found user-password: ' '
which is not possible.
Can somebody help me?
The acrobat version I use is 4.0 and I need to find again the password I cannot remember to use on my own files.

I wonder if this can be done with named pipes.

Instead of (or in addition to) adding newfangled password attacks, how about allowing another application to feed passwords to pdfcrack? Passwords could be printable, but might also be binary.
This would help those who have some idea of what form the password takes. For example, if someone knew that the password was a dictionary word followed by some digits, he could hack some awk/whatever...

Very good improvement, thanks a lot ! It goes about 1.74 times faster with with dual core.
Why don't you put it as a new release in source force ?.

Thanks.

Hi guys,
what does the last param of fseek do? In pdfparser.c, function getEncryptedInfo()
> fseek(file, 0L, SEEK_END-1024)
See: http://www.cplusplus.com/reference/clibrary/cstdio/fseek/
Thanks
Peter.

Can someone explain me why pdfcrack on windows is much faster then on linux? I have tried a dozens of compiler flags in no vain. Does anybody observed this phenomenon or is it just me?.
