Free Book About PHP Available

[Janina Sajka]

Brian:

The XPDF home page at http://www.foolabs.com/xpdf/cracking.html says the 
following:


   "If any security features are turned on by the creator of a PDF 
document, the PDF file will be encrypted. These
   security features let an author disallow printing, copying 
text/graphics, editing, and/or adding annotations.

   "The Xpdf package honors these permission settings. Specifically:
     * xpdf will not copy/paste from a PDF file which disallows copying 
text/graphics
     * xpdf and pdftops will not print (convert to PostScript) a PDF file 
which disallows printing
     * pdftotext will not convert a PDF file which disallows copying 
text/graphics
     * pdfimages will not extract images from a PDF file which disallows 
copying text/graphics

   "I occasionally get email asking if I can explain how to crack a PDF 
file, or if I can help decrypt a PDF file. I won't
   help these people because I believe that an author's requests relating 
to the use of his/her work should be honored."

Of course, there are patches out there to inhibit these restrictions and a 
soon to be published paper from AFB will demonstrate that people who are 
blind have the legal right in the U.S. to circumvent such measures. Some 
of these patches are referenced at the page entitled "A Gallery of Adobe 
Remedies," which is at http://www-2.cs.cmu.edu/~dst/Adobe/Gallery/, though 
I have not succeeded in getting the ones I've tried to work.

Are you saying that the Debian distribution of XPDF inhibits these 
restrictions by default?
