Unfortunately I cannot help you there as I do not have windows and do not distribute the windows binary. It depends possibly more on compiler version than options but some good things to try apart from different compiler could be -Os or -O2 instead of -O3. Other -march and skipping -fno-reorder-functions might also have an impact.
My own compiler flags are usually not set for speed but to...

Hi there,
The speed differences are within 15% which I suspect are due to different compile flags and/or different compiler versions.
The platform should not really matter anything noticeable for pdfcrack as it only does number crunching and no disc or platform specific usage.
To make a proper benchmark on two different platforms you need to use the same compiler and compiler flags and...

Yes, if it is password protected and latest pdfcrack says that it is not I would appreciate if you could send me the pdf or upload it somewhere so I can investigate what the cause is.
I have not seen any such pdf before so I have been unable to look into it.

Hi Rick,
Unfortunately I do not have enough information from that to say what the cause of your problem is.
Would it be possible to provide the following information?
1. pdfcrack version (run "pdfcrack -v")
2. Either a link to the pdf if online or possibly sending it to me by e-mail (it will be kept confidential and only used for internal testing when fixing the problem)...

Ops, a small correction...
The _R_ and V values are used for determining the correct routine.

Hi Bryan,
I assume you mean the values that are spit out when pdfcrack have parsed the pdf, right before starting the cracking (which is also seen in the state files when saving state).
V = Version of the Security Handler
R = Revision of the Security Handler
P = Permissions of the document, as a integer
The P and V values are used to determine which routines that are used and the...

Hi Marek,
I know, the missing multithreading is the number one requested feature but unfortunately noone has stepped up to do it, and I simply lack motivation and time at the moment.
The difference between OS X and Windows is quite interesting, but I need a bit more details to actually find out what it could be.
First a few things you should know about pdfcrack:
1. The reported...

Null pointer dereferences fixed in pdfcrack-0.11.
There is still something weird in the pdf which I would like to investigate, but without further information I cannot look into it.
Please open a new report or contact me privately if you wish to follow up on this.
Sincerely
Henning Norén.

Thank you for the detailed report!
I have resolved the issues but I wonder if there is some other underlying parsing issue as this specific codepath should never be hit for a normal document.
This means that there is some kind of encryption object referenced in the trailer but pdfcrack does not find it correctly, or there is something obvious I missed.
Would it be possible for you to...

Fixed in v0.10.
