When you set up the DeDRM plugin you also have to find your personal decryption key which will be stored somewhere by ADE after you log into it, and copy that into the plugin. Finally you point Calibre+DeDRM at the encrypted epub file and it decrypts it. Then you load the ACM file into your old version of ADE, and it downloads the encrypted. The way it works in practice is that books stores will let you download an "acm" file for the protected book, which is a pointer to the book in ADE. I used to used this as my main method, but the hassle of getting the old version of ADE to install and run reliably has caused me to give up on it. This is because newer versions use an encryption method that hasn't been broken, and if you download a book through the newer version it will be locked to that newer version. HOWEVER, in order to make it work you have to find and install a VERY OLD version of the ADE software (version 2.0). I'll relate my experience with the three I have used.Īdobe Digital Editions: this has the advantage that it works with most stores that sell epub (so everybody _but_ Amazon) and supports getting the books directly on your computer without having to have a device. The DeDRM tools are actually made up several plugins that deal with different kinds of DRM used by different ebook stores. If you just search for DeDRM you'll tend to find the Apprentice Alf version, but you really want the noDRM version which is more up to date. The best source for the DeDRM plugins is - these plugins used to be maintained by Apprentice Alf, but they no longer have the time. After you install Calibre, the next step is to install the DeDRM plugins. It also supports plugins for doing various things, and one of those is stripping DRM. Calibre is an application for managing libraries of ebooks, and converting them between formats.
