Hi, Walter.
The NR3 files are standard PDF files, in the sense that they completely follow the specifications set by Adobe. However, the Adobe specifications allow for the possibility that the content of the PDF file is stored in an encrypted form, and that the decryption algorithm is in a plug-in. The specific plug-in that we use, the FileOpen plug-in, verifies that your specific machine (as defined by hardware configuration and stored subscription information) is authorized on a specific subscription. If it is authorized, it decrypts the file (all within Adobe Reader). If not, not. So your statement that anyone with the plug-in can read the file is not correct -- they also have to be subscribers.
There is no such thing as perfect security, and we are certainly not attempting that -- there are at least several holes in the above security model. But, for now, it seems good enough to allow an acceptable business model and let us offer NR3 online. If the FileOpen security model ever got seriously broken, we would probably have to remove NR3 from the web, which would be too bad for legitimate users (and for us!).
Cheers,
Bill P.

What Is FileOpen? FileOpen document rights management is a flexible SaaS system for encrypting and authenticating digital documents at scale. Built upon standard document formats and application security frameworks, FileOpen allows you to deploy enterprise-grade document security with a lightweight footprint for both administrators and end-users. From the Finder find Applications:Adobe Acrobat/Reader; Select the launch icon for the viewer, click Apple+I; From the list of options select Plug-ins; Find FileOpen.acroplugin and choose Remove ('-' on 10.5) You may have a folder in your Library:FileOpen, which can be deleted. Download usb extreme ps2. Type: 'chrome://settings/content' into the URL bar. A 'Content Settings' box will appear. Scroll to the bottom of the 'Content Settings' box and select 'Open PDF files in the default PDF viewer application' option. Click on the 'Done' button in the bottom right corner of.

A large amount of useful content is now encoded as PDF (PortableDocument Format) files, including files marketed for eBook documentreaders. Unfortunately, some of this content is not usable in all thelawful ways a purchaser desires, due to access control mechanismscreated by Adobe and adopted by content publishers to the detriment oftheir customers. Computer professionals who have examined thesemechanisms have found them easy to defeat. This web site will publishinformation about Adobe's access control mechanisms and the remediespeople have devised to deal with them. Here are directories of linksfor removingPDF security and PDFpassword tools. You can, for example, purchase Eltima's Recover PDFPassword for Mac or RecoverPDF Password for PC.ineptpdf (Google it) is a tool for bypassing fileOpen PDF encryption.

June 2010: new fileOpen circumvention tool available from Tetrachroma:click herefor information.

A while back, an anonymous contributor sent the source for fileSaveAs.c a program that 'reads a pdfencrypted with the fileOpen plugin, and attempts to write a plainpdf.' I have no way to contact the author, but you can send bugreports to me and I'll post them here.

Xpdf is an open-source PDF viewer for Unix, VMS, OS/2, and Windows,available at http://www.foolabs.com/xpdf.The documentation of the decryption feature says: 'If anysecurity features are turned on by the creator of a PDF document, thePDF file will be encrypted. These security features let an authordisallow printing, copying text/graphics, editing, and/or addingannotations.'

David E. Smith at technopagan.org has created a patch to Xpdf that disables thesecurity features. The patch (revised July 24, 2001) is available here. Mr. Smith writes: Patch xpdf (thediff is against 0.92 but should be easily adaptable to future version)and feed '--enable-antikick' to 'configure'. The patch is bigger thanit should be; all but the bottom twenty lines or so are diffs to the'configure' script itself. The name 'antikick' came from HarlanEllison's 'Kick Net Piracy' campaign, btw. Ironically, I fully supporthim in this..

HansNieuwenhuis has contributed an Xpdf patch for version 0,93,also available at http://vzzbx.xs4all.nl/files/xpdf-0.93-ro-remove.patch. See his web page onthe patch for more information. (Older 0,92 version here and here.)Mr. Nieuwenhuis writes that the difference between Mr. Smith's patchand his are that his does not disable printing protection, it onlyre-enables copy and paste. FreeBSD incorporates this patch into theirxpdf port.

An anonymous correspondent has sent generic Xpdf patch instructionsthat work in versions 0.92 and 0.93 and should be easily adaptable toall future versions, and another anonymous reader sent in a patch file for xpdf 3.00. Yet anotheranonymous correspondent had a comment about printing protection.

Erik Hovland contributed this patch for XPDF version 3.02p12.

Poppler is a PDFrendering library based on the Xpdf 3.0 code base. Eriv Hovland hasthis patch for poppler release0.6.4.

A helpful reader wrote in to remind me that: 'GhostScript/GhostView.. handle PDF just fine and have been completely bypassing itsrestriction schemes for quite some time without much fanfare. Thereare precompiled versions for most popular OSes, donwloadable from manyplaces.

The home page for Ghostscript is http://www.cs.wisc.edu/~ghost/

The sourceforge project page for Ghostscript is http://sourceforge.net/projects/ghostscript/

Geoffrey Keating's EncryptedPDFs page offers appropriate patches to Ghostcript for readingencrypted PDF files. For versions 4.01 and higher, use pdf_sec.ps

Kyler Laird's PDFutilities build on Geoffrey Keating's work. Laird offers a webform you can use to convert PDF files to Postscript, and a hack for turning on printing for encrypted PDFfiles. Thanks to reader Rashkae, who adds: 'You can then doa pdf2ps and back again with ps2pdf to generate a clean, unencrypted,printable, PDF file.'

Rusty Mase, a professional cryptanalyst, challenged KylerLaird to crack a sample PDF file he supplied. To Mase's surprise,Laird did it. See if you can do it too.

An anonymous contributor tells how to Convert aprintable Adobe eBook to an unprotected PDF file by following these simple steps.

Marc Hoffman announced(see March 3, 2002 entry) that the document previewer bundled with MacOS X allows one to strip the security features from a PDFautomatically simply by printing the document to a Postscript file andredistilling it. Read his report, Disabling Security Settings in AcrobatFiles. The claim in the report that password protection willprevent PDF unlocking turns out to be untrue; the version of thedocument provided here, by a third party, has the password removed.The document is posted with Mr. Hoffman's permission.

Another correspondent wrote in January 2006 that she didn't even needto save the document as a Postscript file; it sufficed to 'print' itas a PDF under a different name.

But in February 2006, someone informed me that Preview Version 3.0.4(398) under Mac OSX 10.4.5 does not permit these operations onpassword-protected PDF files.

An anonymous informant writes: The Adobe Acrobat Access Plug-in4.05 enables vision-impaired users to read Adobe PDF documents inAcrobat 4.0x or Acrobat Reader 4.0x.

The Access plug-in supplements the standard Acrobat and Reader displayof PDF documents with an alternative view that supports screen-readingapplications for Microsoft Windows 95, Windows 98, and Windows NT.This view presents the textual content of a PDF file in a separatewindow. The window contains the text in an approximated readingorder. Standard Acrobat features, such as hypertext links, notes,bookmarks, sounds, and movies, are available in the Access view.

Once this is installed, press control + 4 to move to 'TEXT' mode.This mode enables you to copy it to a text2speech program .. orwherever you want. I've tested it in Acrobat 4 and it works. Youthen press Control + e to move back to the standard viewing mode.

An anonymous source hasprovided instructions for removingsecurity from Amazon-purchased eBooks. This requires Acrobat 6;Acrobat 7 reportedly does not work.

Another anonymous source writes: 'I tried using Scansoft PDF creatorto print to a PDF file. I then found I could read the printed PDFfile in other machines.'
