# DeDRM_tools
DeDRM tools for ebooks
This is a repository that tracks all the scripts and tools for removing DRM from eBooks.

This is a fork of Apprentice Harper's version of the DeDRM tools. Apprentice Harper said that the original version of the plugin [is no longer maintained](https://github.com/apprenticeharper/DeDRM_tools#no-longer-maintained), so I've taken over, merged a bunch of open PRs, and added a ton more features and bugfixes.
The provided plugins should work with both Calibre 5.x/6.x (Python 3), as well as Calibre 4.x and lower (Python 2).<br>
If you encounter issues with the plugins in Calibre 4.x or lower, please open a bug report.

The latest stable (released) version is v10.0.3 which [can be downloaded here](https://github.com/noDRM/DeDRM_tools/releases/tag/v10.0.3). The latest beta is v10.0.9, as a release candidate for v10.1.0. It [can be downloaded here](https://github.com/noDRM/DeDRM_tools/releases/tag/v10.0.9).
The original repository of Apprentice Harper [is no longer maintained](https://github.com/apprenticeharper/DeDRM_tools#no-longer-maintained), so I've taken over, merged a bunch of open PRs, and added a ton more features and bugfixes.

The latest alpha version is available [at this link](https://github.com/noDRM/DeDRM_tools_autorelease/releases). This version is completely untested and will contain the latest code changes in this repository. With each commit in this repository, a new automatic alpha version will be uploaded there. If you want the most up-to-date code to test things and are okay with the plugin occasionally breaking, you can download this version.
## FAQ

Take a look at [the CHANGELOG](https://github.com/noDRM/DeDRM_tools/blob/master/CHANGELOG.md) to see a list of changes since the last version by Apprentice Harper (v7.2.1).
You are urged to read the [FAQ](FAQs.md).

My version of the plugin should both work with Calibre 5.x/6.x (Python 3) as well as Calibre 4.x and lower (Python 2). If you encounter issues with this plugin in Calibre 4.x or lower, please open a bug report.
The most common issue you may run into is that you cannot load the nested archive with all the tools into Calibre.<br>
You need to unarchive the downloaded tools archive, to get just the archive with the standalone plugin.<br>
Beta versions may be just the plugin, don't unarchive that.<br>

# Original README from Apprentice Harper
There is also a general [README overview](ReadMe_Overview.txt).

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. (Except for the Requiem tools for Apple's iBooks, and Convert LIT for Microsoft's .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.
## Versions
The latest stable release is v10.0.3, [available here](https://github.com/noDRM/DeDRM_tools/releases/tag/v10.0.3).<br>

The individual scripts are now released as two plugins for calibre: DeDRM and Obok.
The DeDRM plugin handles books that use Amazon DRM, Adobe Digital Editions DRM, Barnes & Noble DRM, and some historical formats.
The Obok plugin handles Kobo DRM.
The latest beta is v10.0.9, as a release candidate for v10.1.0, [available here](https://github.com/noDRM/DeDRM_tools/releases/tag/v10.0.9).<br>

Users with calibre 5.x or later should use release 7.2.0 or later of the tools.
Users with calibe 4.x or earlier should use release 6.8.x of the tools.
The latest alpha version, completely untested, [available here](https://github.com/noDRM/DeDRM_tools_autorelease/releases).<br>
With each commit in this repository, a new alpha version containing the latest code changes will be automatically uploaded.<br>
If you want the most up-to-date code to test things and you are okay with the plugins occasionally breaking, you can use this version.

For the latest Amazon KFX format, users of the calibre plugin should also install the KFX Input plugin from the standard calibre plugin menu. It's also available from the MobileRead thread here: https://www.mobileread.com/forums/showthread.php?t=291290
## Tools

The individual scripts are released as two plugins for Calibre: DeDRM and Obok.

See the [plugin README overview](DeDRM_plugin_ReadMe.txt).<br>
For using the tools on CLI, see the [Calibre CLI README](CALIBRE_CLI_INSTRUCTIONS.md).

### DeDRM

The DeDRM plugin handles books that use Amazon DRM, Adobe Digital Editions DRM, Barnes & Noble DRM, and some historical formats, see the [DeDRM README](DeDRM_plugin_ReadMe.txt).

For the latest Amazon KFX format, users of the Calibre plugin should also install the KFX Input plugin from the standard Calibre plugin menu, or manually from [the MobileRead thread](https://www.mobileread.com/forums/showthread.php?t=291290).

Note that Amazon changes the DRM for KFX files frequently. What works for KFX today might not work tomorrow.

I welcome contributions from others to improve these tools, from expanding the range of books handled, improving key retrieval, to just general bug fixes, speed improvements and UI enhancements.
### Obok

The Obok plugin handles Kobo DRM, see the [Obok README](obok_plugin_ReadMe.txt).

## Changelog
Take a look at [the CHANGELOG](CHANGELOG.md) to see a list of changes since the last version by Apprentice Harper (v7.2.1).

I urge people to read the FAQs. But to cover the most common: Do remember to unzip the downloaded archive to get the plugin (beta versions may be just the plugin don't unzip that). You can't load the whole tools archive into calibre.
## Contributions

My special thanks to all those developers who have done the hard work of reverse engineering to provide the initial tools.
Contributions are welcome, including, but not limited to:
* Speed improvements and UI enhancements
* Expanding the range of books handled
* Improving key retrieval
* General bug fixes

Apprentice Harper.
Special thanks to all the developers who have done the hard work of reverse engineering and provided the first DeDRM tools.
