Adobe Digital Editions is ebook reader software from Adobe Systems built using Adobe Flash. It is used for acquiring, managing and reading eBooks, digital newspapers, and other digital publications. The software supports PDF, XHTML (through the nonproprietary .epub file type specification), and Flash-based content. It implements a proprietary scheme of Digital Rights Management, which since version 1.5 (May 2008) allows document sharing between multiple computers and user authentication through Adobe ID.

Windows and OS X versions of Adobe Digital Editions were released on June 19, 2007. The software requires version 9.0 of Adobe Flash Player. Adobe originally announced a Linux version would be published at the end of 2007 but later changed their mind. [1]. All promises of future versions have now been removed from the Adobe's official FAQ.

[edit] Digital rights management

Adobe Digital Editions uses the proprietary ADEPT (Adobe Digital Editions Protection Technology) digital rights management scheme, which is also implemented on some e-book readers such as the Sony Reader. The software locks content to up to 6 machines and allows the user to view the content on each of them. It is not so much an encryption system as one of obfuscation.

In March 2009, the author of the reverse engineering blog i♥cabbages claimed that he had broken the scheme.[2]
