Adobe ADEPT DRM for PDF circumvented

The common denominator among all those that turned out this way is that they are downloaded thru .acsm and not ebx.etd...
Then, I tried with a test file from diesel-ebooks (using .acsm) and I was able to open it... Yet, I got the previous error with the books I bought from there.

This will only work with books downloaded or activated with Digital Editions, but should work for all of them. If you (or anyone else) has a PDF which opens in DE but doesn't decrypt properly, please e-mail your key file and the PDF file to <i.u2665.cabbages@gmail.com> and I'll try to sort it out.

Sure. Bought from ediesel w/Acrobat Reader 6 years ago. Imported into DE when DE for Sony Reader came out, opens fine in DE on Windows as well.

I really want topaz next, all the books I want on Amazon are in topaz.

Thanks, man, that's excellent news!
I've yet to try it but I'm sure it'll do nicely, as the ePub one! Thanks again!!

Aah, I bet that's it. PDF files downloaded by Acrobat 6 and Acrobat 7 are slightly different than those downloaded directly by Digital Editions. The old "find 'Print First' in the PDF file and modify it, then open it in Acrobat 6" trick wouldn't work in Digital Editions-downloaded files, because there was no "Print First" line to find.

If there's no way to re-download the PDF with Digital Editions, it may require another version of the script to strip the DRM...

Yea... if he is old enough to drink.

One remark:

Of course the script doesn't remove (personal tracking) ids in the content (not the metadata) of the PDF. That means if the ebook provider inserted some tracking URIs (check for the codeword with a hex editor or search for hyperlinks) you have to remove and substitute it yourself. The same occures with watermarks or similar methods.

I have found a personal tracking id in an URI in my providers pdf so it is recommended to check for that before you 'loose' your ebook to somebody else (to be clear: of course I don't support piracy) ...

Alternatively you can add the substitute command in the

def escape_string(self, string):

function (worked for my provider).

We all assume you are doing the right thing and only using this on eBooks that you have purchased for your own use and you aren't passing out ebooks after you decrypt them.

If you aren't "loosing" the books, as you shouldn't be any way there is no need to worry about identifying info on the files.

You're right in that point (over the time I have bought over 200 drm'ed ebooks for myself) but I still was shocked that they included some tracking items in my ebook.

Its none of their business how long I read which ebook. I'm very concerned about my privacy.

They aren't putting some wireless account reading devices on paperback books.

That doesn't sound so bad to me, actually. I think I might be a fan of "social DRM." It doesn't prevent you from using the file in any particular way or sharing it with any particular person, but provides some disincentive for out-right piracy (yarr!).

Think about a device which records when you're sleeping, when you're eating, when you're at the bathroom and when you're having sex.

Well, for some people that is not a problem but in my opinion it's none of their business what I do in my free time (as long as it's in the law).

And think about the possibilities. Imagine they would get that you were reading a book about sex longer than the average pearson. How long would it take that somebody will call you and make you an offer related to that ...
