Adobe ADEPT DRM for PDF circumvented

i♥cabbages · 02-25-2009, 10:41 PM

Déjà vu time! I have successfully and reproducibly circumvented Adobe's ADEPT DRM system for PDF files. A discussion of the system and the circumvention is available in a blog post I've made on the subject: Link removed

I don't have any DRM'd PDF's anymore, but I tried it out on Whiskey Rebels (one of the free Random House books) and it worked perfectly.

I get "Error -5 while decompressing data." This PDF was downloaded with Acrobat 6.0 Professional; perhaps you have to download with Digital Editions? I'll find out.

Yep, it works fine when downloaded with Digital Editions. So those who have been using the old Acrobat 6.0 extract trick will have to re-download their files with Digital Editions.

i♥cabbages - we love you too! Thank you - so many really good library books are available only in Pdf. We mobi people now have a new world of pdf thanks to you.
Works like a charm - Much appreciated!

Interesting. Decrypts recently loaded (via DE) pdf's just fine. Can't decrypt the file that was bought ages ago and imported in DE. Error message is "can't find book session key".
