Just because they pass a virus scan, or cost a lot, does not mean they are safe.
New viruses, bugs, and backdoors are made all the time. At least with open source there are many eyes presumably reviewing the code. The mere presence of source code does not guarantee absolute safety. Therefore, the best security practice is to review and compile the code for oneself, or rely on a trusted software distribution center, or distro, to review and compile the code and provide signed binaries for download. Our research indicates that there are at least three broad, general types of protections for PDF files.
PDF unlocker programs found on the Internet today only deal with user password and owner passwords. None of these programs deal with PDF files that encrypt the content using 3rd party plug-ins but we can remove the plugins using free and open source tools, provided that we can use the password first to unlock and permit the plugin to download the secret content.
PDF files with 3rd party plug-ins have a login page on page 1, where the viewer enters their username and password. The remaining pages appear blank until they are unlocked.
This requires an active Internet connection. If the computer is offline, Adobe Reader will respond with a not-so-friendly " unknown error " and can't open the PDF.
Once connected and the unlock request finally gets through, the 3rd party server verifies the login and either responds with the actual content, or exchanges a certificate to unlock the file contents for viewing. From that point on, Adobe's reader may prevent access if the file has been copied to another device, or even to another location on the same PC.
Additional JS may track the file whenever and wherever it is opened, reporting potential Copyright violations. Usually a document that uses 3rd party JS is also restricted using one or more of the following security signatures as well. According to PDF Rights Management , Adobe's questionable implementation of Digital rights management DRM controls and security signatures started with allowing the creation of documents with any of the following restrictions:.
Later PDF restriction possibilities were refined to include restricting assembly, extraction for accessibility, commenting, filling in form fields, signing, or template creation.
Starting with PDF 1. Students using the popular Bookshelf online ebook viewer web page can print copies using "print frame" or "save frame" techniques.
Bookshelf's print button may say something like, "printing of this title is restricted to two pages at a time," with restrictions set by publisher. Simply open the book in Bookshelf's online viewer, right-click on the frame containing the book or chapter, choose "this frame", and either "print frame", or "save frame". All pages are printed or saved. Not using Bookshelf?
Find an unencrypted copy of the ebook viewable or downloadable online. With so many file sharing sites, ebook readers, and search engines out there, one can find earlier versions, or unencrypted copies of just about anything free or cheap.
FTP it. Usenet still exists Proprietary Viewers. This requires purchase and activation of Bookshelf app on up to two machines.
It is doubtful that the resulting downloads can be copied or shared as they would remain encrypted and controlled within the Bookshelf downloads folder where they can spy on users and report on their whereabouts when opened.
Bookshelf apps appear to be proprietary and not recommended. This method entails first downloading the PDF ebook, and running qpdf on the download using the --qdf option to normalize and uncompress the data. Once normalized and uncompressed, the PDF may be unlocked from within Adobe Reader and printed to file. The resulting PostScript file is unprotected and may be freely redistilled converted back to PDF with Ghostscript 's ps2pdf.
No more "Redistilling encrypted PDF is not permitted" message! This method entails using Adobe Reader to unlock the file via the Internet in the usual way and then print to file. The resulting PostScript file is protected and has to be hacked with sed before it can be redistilled converted back to PDF with Ghostscript 's ps2pdf.
The conversion process runs very slowly because of PostScript errors introduced from the sed hack, but it is good for small chapters when technique 1 does not work, or when qpdf can not be installed on the system.
If somebody creates a PDF and then loses the password, they can recover the password with the pdfcrack command line password recovery tool. The tool leverages a brute force attack against the PDF password until it opens.
The attack proceeds offline and nothing is exchaned via the Internet. Owner passwords can be found with the -o switch. Password cracking of longer passwords can take days or weeks to crack, so we limit the password length to 9 characters.
This hack can not and does not work over the Internet with content locked by a 3rd party JS plugin. How could it? It would have to hack into the 3rd party server to do that!
Google will convert the PDF for viewing online. Google Drive limits uploads to 2Mb. This hole may become patched in later versions.

Caveat emptor buyer beware. These programs do not really unlock 3rd party JS plugins.
Some demos available online even spend a minute conducting a fake test that pretends to open the file. They say the PDF can be unlocked, but then, after purchase, these programs unlock file passwords only. They do not actually work against 3rd party JS server passwords. How could they? They would have to hack the server to do that.
