Users with calibre 5.x or later should use release 7.2.0 or later of the tools. The DeDRM plugin handles books that use Amazon DRM, Adobe Digital Editions DRM (version 1), Barnes & Noble DRM, and some historical formats. The individual scripts are now released as two plugins for calibre: DeDRM and Obok. lit ebooks.) This includes the tools from a time before Apprentice Alf had a blog, and continues through to when Apprentice Harper (with help) took over maintenance of the tools.

(Except for the Requiem tools for Apple's iBooks, and Convert LIT for Microsoft's. This is a repository that tracks all the scripts and other tools for removing DRM from ebooks that I could find, committed in date order as best as I could manage. I shall be using noDRM's version of the tools from now on. I am delighted to find that someone else has taken on the task of keeping the tools updated, and making releases. I just want to be able to save my favorite books so I don't lose them.I have not had the time to devote to this project in recent years that I would have liked. The only reason I'm trying to do all this is because of stories about ebook sellers that suddenly decide to delete a user's entire library. I navigated to DeDRM_calibre_plugin > DeDRM plugin > allcrypto_src which has an empty file called allcrypto_src. Then went back to Calibre > Preferences >Plug Ins > Load plug in from file. I ended going into File Explorer and found this file and unzipped it. When I tried to unzip this file, I got an error message saying it does not contain a top-level init.py file.

I opened DeDRM_calibre_plugin > DeDRM_plugin and saw a zipped file called allcrypto_src. The website said to open Calibre, click on Preferences, Plug Ins, and then Load plug in from file.

Then clicked on DeDRM_calibre_plugin and DeDrm_plugin and clicked on the Extract All button. I downloaded Calibre and then downloaded DeDRM_tools_6.6.1.zip and unzipped it.
