#17 Options to specify character set as Latin-1 or full Unicode

Kjetil Kilhavn — Fri, 08 Dec 2023 06:10:18 -0000

Thanks for the command line trick - I'll copy that to my ReadMe.pdfcrack file :-)

It's soon 30 years since I last coded anything in C. Haven't looked at the source code yet (just downloaded it), and with the tasks for the marching band and an archery club there's not a lot of time available.

This is a stereotypical 'scratch my own itch' situation, and national holidays are coming up to celebrate the end of the year (or 'turning of the sun'). Maybe I can find time to brush the dust off my C knowledge.

#17 Options to specify character set as Latin-1 or full Unicode

Thanks for the request!
I posted a response in the bugticket how to handle those, but I would not be reluctant to patches for the same if anyone would bother coding them up.

In case sourceforge ever manages to mess up the links to bugs, here is the trick:
* Put the charset you want in a file (usual UTF8 encoding, should probably be standard nowadays)
* Use iconv to convert the file to your chosen encoding (here ISO-LATIN-1):
iconv -f UTF-8 -t ISO-8859-1 latin1.txt > latin1-actually.txt
* Read in the file as a variable and make use of that:
CHARSET=$(cat latin1-actually.txt); pdfcrack -c "$CHARSET" -f filename.pdf

Options to specify character set as Latin-1 or full Unicode

With reference to https://sourceforge.net/p/pdfcrack/bugs/13/ I propose two new command-line options to specify which character set to use.
* One to specify the full Latin-1 (displayable or printable) character set
* One to specify the full Unicode (displayable or printable) character set

#16 Please van you kindly add support to 256 bit encrypted PDF files

Unfortunately no news, pdfcrack is basically in maintenance mode for me as I have little interest or update it (although I do update for bug-fixes still, if reported).
The latest PDF standard is at least added to now poppler (probably xpdf also, that pdfcrack was based on) so those libraries could exemplify how to support it if someone puts some time into it.
Patches are welcome, but currently I have no real interest in doing it.

Any news on this request? PDFcrack seems great but I used it for the first time today and it returned "The specific version is not supported (Standard - 6)" which apparently means that 256-bit uncryption is not supported. So I am looking forward to the next update...
Many thanks for the work already done!

Hi.

1st of all, let we say congrajulation for your return to project after long inactivity time ! I was very exited when I detected few days ago that there are new recent release & fix ....

Currently, your great program not support 256 bit encrypted PDF files. This is very disappointing as many modern PDF have such encryption level. It will be very useful to see pdfcrack support 256 bit encryption.

#6 Multi-Core!

BlueGroper — Wed, 03 Feb 2016 03:29:48 -0000

Right now I have a pdfcrack (version 0.14) background job running on small CentOS 7 (RHEL clone) server.
Nothing special about setup, just yum install pdfcrack as normal.
Monitorix shows this job is using BOTH cores of an Athlon dual core CPU.
Log shows average speeds around ~ 82,000 w/s.
YMMV

#12 Feature request: option to log output to file as well

BlueGroper — Wed, 03 Feb 2016 03:22:29 -0000

In linux you can write and watch the logfile :

$ pdfcrack myfile.pdf > mylogfile.txt &
$ tail -f mylogfile.txt

HTH
