1 --- 2 title: "Removing ACSM DRM from E-Books" 3 date: 2018-11-24T10:22:00 4 tags: ["Books", "Guides", "Software", "Windows"] 5 --- 6 Recently I found a rare-ish e-book available via the Internet Archive's [Open Library](https://openlibrary.org/) project, there was a waiting list and I wanted to read this on my Kindle without needlessly tying it up for other people wanting to read it. 7 The combination of these two circumstances leads me to stripping the DRM from this file so I could work with it how I wanted. 8 9 Firstly, you'll need to install [version 2.0.1 of Adobe Digital Editions](https://www.adobe.com/support/digitaleditions/downloads.html) as newer versions use a newer encryption scheme. With this installed, authorise your computer and open your `acsm` file to verify everything's correct with the book. 10 11 Next, you'll need to install [Calibre](https://calibre-ebook.com/) which you should probably already have installed if you're working with Kindles in any real manner. 12 13 Next, you should grab the latest release of the excellent [De-DRM Tools](https://github.com/apprenticeharper/DeDRM_tools/releases) by Apprentice Harper. With this downloaded, extract the contents of the file, open Calibre and add the plugin via Preferences > Plug-ins > Load plug-in from file. The file you want is `DeDRM_plugin.zip`. Restart Calibre and the plugin should be installed. 14 15 Lastly, grab the plain `epub` file from your `%userprofile%\documents\My Digital Editions` directory. Import this into Calibre by dragging it into the main window and you're done. A file you can work with at long last. Now return that book so other people can read it.
