PDFCrack source code has been released over a month, but there is still no windows binary version, so I decide to do it, and it come to the world.

http://blog.rubypdf.com/pdfcrack/

I do noting, but use Cygwin to compile PDFCrack under Windows XP
If you want source code, please download from PDFCrack project page.

Features available in this release (check TODO for features that might come):
* Both owner- and user-passwords with the Standard Security Handler, rev 2 & 3.
* Search by wordlist
* Search by bruteforcing with specific charset
* Optimized search for owner-password when user-password is known (or empty)
* Extremely simple permutations of passwords (makes first letter uppercase)

- currently only useful for bruteforcing with charsets:
* Auto-save when interrupted (Ctrl-C or send SIGINT to the process)
* Loading saved state

- currently only for bruteforcing with charsets:
* Minimum length of password to start at
* Maximum length of password to try

Sort your wordlist by length for best performance and consider that almost
all passwords in PDFs are in iso latin 1 so use the correct character encoding
in your terminal and/or wordlist when using special characters.

This tool can not decrypt a Password Protected PDF.
Look up the pdftk toolkit which can do that, when you know the password.

PDFCrack - A Password Recovery Tool for PDF-files

From OpenOffice.org 3.0 Beta Features I noticed some great features about PDF,
*PDF/A Support

In addition to the ISO standard OpenDocument Format (ODF), OpenOffice.org also supports the the popular ISO standard PDF/A. While ODF is used for editable documents, PDF/A is popular for archiving read-only versions of documents.

*Enhanced PDF Export

The PDF export feature in OpenOffice.org provides a huge set of formatting and security options; so that PDF files can be customized for many different scenarios.

*PDF Import Extension

The PDF Import Extension allows modifying existing PDF files for which the original source files do not exist anymore. PDF documents are imported in Draw and Impress to preserve the layout and to allow basic editing. It is the perfect solution for changing dates, numbers or small portions of text. Native PDF forms are not yet imported.
The next development step will focuses more on the edit capabilities and less on layout by using the Writer.
The PDF Import extension will also enable the PDF export into a hybrid PDF file, which is a PDF with the embedded source file as ODF. Hybrid PDF files will be opened in StarOffice as an ODF file without any layout differences, while users without StarOffice can open the PDF part of the hybrid file.
This is just a beta version and it requires the OpenOffice.org 3.0 beta 2 to work. Please help us to optimize this Extension, any feedback is important for us. Find details about the preferred channel in thisGullFOSS article
