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...

Today i am going to explain one more software cracking tutorial to crack Adobe software or products manually. By using this trick you can crack all adobe software's like Adobe Photoshop, Adobe Creative Suite, Adobe Dreamweaver, Adobe Lightroom, Adobe Fireworks, Adobe Premiere Pro, Adobe illustrator, Adobe Flash, Adobe Director etc.

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:

Fileopen Plugin For Adobe Cracker

'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/

Also see the GNU Ghostscript page.

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.'

Putting A Lock On E-Books, MSNBC.com article (July 19, 2001) bySiva Vaidhyanathan.

I am interested in receiving and publishing the following kinds of information:

• Technical descriptions of the access control and encryptionmechanisms associated with PDF files and/or eBooks.
• Technical descriptions of remedies for these mechanisms, e.g.,patches, key recovery algorithms, modified plug-ins, etc.
• Source code for implementing these remedies.

Mail submissions to DaveTouretzky. Anonymous submissions are fine.

Note: this web site is for discussion of purely technical informationof interest to computer scientists and lawful content users. I amnot interested in receiving rants about Adobe or the DMCA. Go to theBoycott Adobe site for that. RTMPE.txt file In 2009 Adobe used a DMCAtakedown notice to SourceForge to suppress an open sourceimplementation of a network protocol called RTMP. Here is the technical specification and the source code. More info is availablehere.

Thecurrent technology leader in Adobe remedies is a Russian companycalled ElcomSoft.Unfortunately their best-known programmer, Bauman Moscow StateTechnical University computer science Ph.D. student Dmitri Sklyarov,was held in the US for several months in 2001, pending prosecution under theDigital Millennium Copyright Act, and is no longer speaking publiclyabout these issues.

ElcomSoft has announced a new PDF password recovery tool.Details available at their web site and this articlein Wired.

Summaryof Sklyarov's results, by Bruce Perens.

Cryptome mirror ofElcomSoft's AEBPR (Advanced E-Book Processor) software version 2.2,which decrypts 25% of an E-book as a demonstration. Note: ElcomSoftis no longer distributing this software.

And Justice forAdobe, an article by Lisa Rein at O'ReillyNetwork Weblogs, nicely summarizes the case through July 2001.

Anonymous sources have confirmedthat adding the following entry to the Windows registry will unlock the software so that itwill decrypt 100% of a document:[HKEY_LOCAL_MACHINESoftwareElcomAdvanced eBook ProcessorRegistration] 'Code'='LEPR-T2K7-NA8Z-3DUE-EVDQS-TMPV-MBAUB'.

From someone who has personally verified that this works: 'Usingthis program I was able to convert a locked Adobe eBook to PDFformat. I then purchased an ebook from Barnes&Noble only because Ihad a copy of AEBPR. I will not distribute copies of the unlocked PDFfile, but I would not have purchased an ebook in the Adobe format whenit is locked to an operating system on a single computer.'

Problem report:'I downloaded the free trial version ofAEBPR, then edited the registry as indicated in your 'Adobe Remedies'site, and it worked beautifully on the free ebooks I had downloadedpreviously (using Adobe ebook Reader 2.1). I then bought an ebook;however, it was necessary to update to Adobe ebook reader 2.2.Unfortunately, the attempt to decrypt the new ebook resulted in theerror, 'Bad data in the son.dat. Error 2.' Then, 'No EBX booksavailable.'

Adobe has disabled the earlier version 2.2 of their eBook reader, sothat it can no longer be installed on new machines. Theircertification server does not give a certificate for this versionanymore. According to an anonymous reader, a solution to the problemis as follows: Find someone who already has version 2.2 build 200 installed andactivated. Ask him to send you all files from his 'DataVouchers' folder. Put these files in your DataVouchers folder, overwriting your ownones. Run the Reader. It will show the following message: Call Adobe, give them the Challenge, and receive an activationcode. Enter that code into the Reader -- it will updated. Now you canpurchase the books from that version, and use AEBPR to convert them toPDF. I don't have these DataVouchers files,and I don't know anyone who does, so please don't email me asking howto obtain them. -- Dave Touretzky

The old fix to the son.dat problem, sent in by an anonymous reader,was as follows: 'Don't use the current version ofeBookReaderInstall.exe (size: 10,621,400 bytes or 10372 KB.) Insteaduse the earlier version (also named 2.2 build 200!) which has a sizeof 10,582,776 bytes (or 10334 KB). You can find a copy of the earlierversion at: http://www.itacainformatica.it/Download/Programmi/Windows/eBookReader/eBookReaderInstall.exe.If you already have installed the later version of this program,you'll have to uninstall it and remove the DATA folder beforeinstalling the earlier version. Then verify your installation with afree e-book from amazon.com.'This no longer works, since Adobe changed their certification server to block it.
