Foldi-One on Briefcase Computer Is A Glorious Cyberpunk Build.


also took the time to wrap all of his findings up into a neat little tool called OMCStrip, which as you may have guessed, strips the DRM from ADEPT-protected eBooks with ease. After a bit of digging, he finds all the data he needs to strip the DRM from his books. The final part of discussion digs even deeper into the OverDrive Console’s inner workings, where he finds that the OverDrive Media Console stores quite a bit of information in an SQLite database. When he then tries to strip the ADEPT DRM layer from his books however, he discovers that OverDrive is using a non-compliant version of the ADEPT standard, which renders existing tools useless. The second part takes a close look at the OverDrive Media Console itself, where he uses the ineptkey and ineptepub utilities written by to pull the RSA cipher keys from the EPUB data he uncovered. The topic is broken down into three parts, starting with an introduction to the EPUB file structure, the OverDrive Media Console, as well as the aforementioned ADEPT DRM scheme. His research centers around Adobe’s ADEPT digital rights management scheme, which is used to protect the books offered on loan by OverDrive. He wondered what recourse users had if they wanted to view a book they have already checked out on a different, or unsupported piece of hardware. He checked out a couple of books, which got him thinking about how the copy protection scheme was implemented. Local library recently started lending eBooks via the OverDrive Media Console system.
