What can X-PDF-Browser do?
Why should I embed files into PDF?
To transport attachments through overzealous firewalls/mail filters
Maybe you need to send some files in form of a ZIP or EXE, these days some emailer server block such attachments per se - even without looking inside or checking the contents and you cannot get your message through. However PDFs are in most cases not blocked - so just wrap your files into a PDF and send away with instructions to use X-PDF-Browser to extract. (Note to a receiver: You should perform a virus check after extraction! X-PDF will transport any kind of data and proper percautions should be performed just like the way when you receive a ZIP or other archive file. X-PDF-Browser does not execute attachments, it can only unpack them)
To attach files to a PDF in compressed form and secured by encryption
Imaging you are sending someone a PDF but you like to include the source documents e.g. Word DOCs or Excel Spreadsheet files that were used to generate the PDF or serve as additonal data - however you don't want anyone to access these source files. Normally you would create e.g. a ZIP archive with the PDF and the source files as content.
In this case X-PDF-Browser comes handy, it allows you to attach the DOC, XLS, QXP, ... files to a PDF without changing the visuals of the PDF - it still prints and show the same - and optional secure the attached content using strong encryption. Now you can send the other party just one file - the PDF containing all the other files deep inside - and only people knowing the passwords can access the embedded additonal data.
What are the costs for X-PDF-Browser?
X-PDF-Browser is free for personal and educational use.
What are the limits of the 1.0 release?
What encryption does X-PDF-Browser use?
Currently Twofish 256 bit in CBC mode. Public key variants are planed for the next version.
Can such file attachments be extracted by other programs?
Since the encryption is stronger than the default encryption of Adobe Acrobat and the method uses a different approach, attachments to PDF created by X-PDF-Browser cannot be seen by other PDF reading programs. For them the PDF is still fully valid but seem to contain no attachment or additonal data at all. Please understand that X-PDF-Browser does not actively hide the attachments, it only embeds them in a special way so they are ignored (as defined by the PDF specification).
