@ -41,3 +41,7 @@ List of changes since the fork of Apprentice Harper's repository:
- Add code to support importing multiple decryption keys from ADE (click the 'plus' button multiple times).
- Improve epubtest.py to also detect Kobo & Apple DRM.
- Small updates to the LCP DRM error messages.
- Merge ignobleepub into ineptepub so there's no duplicate code.
- Support extracting the B&N / Nook key from the NOOK Microsoft Store application (based on [this script](https://github.com/noDRM/DeDRM_tools/discussions/9) by fesiwi).
- Support extracting the B&N / Nook key from a data dump of the NOOK Android application.
- Support adding an existing B&N key base64 string without having to write it to a file first.
