Some observations regarding my previous entry, which received WAY much more attention than I had expected :-)
- John Dowdell (who works for Adobe), Duane Nickull and some commenters on this blog were quick to point out that the term “PDF DRM” is maybe a bit wide. That is, the circumvention trick only works with PDF files with an “owner level password” (preventing you from printing, or copying snippets). On the other hand, “user level password” protected PDF files (the ones that prompt for a password when you want to open them) and Adobe’s server side rights management setups are obviously NOT affected by the hack I described.
- There were quite a bit of incoming links from Asian (mostly Chinese) blogs and forums — first time that happens.
- Apparently, there is a Firefox extension that does the exactly the same thing: check out PDF Download 0.6.
- Several people pointed out that circumventing PDF copy/print restrictions is possible in a number of other ways, KPDF being one of them.
