|

- 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.
|
||||
- Support adding an existing PassHash / B&N key base64 string without having to write it to a file first.
|
||||
- Support extracting PassHash keys from Adobe Digital Editions.

<li>B&N: The NOOK Android application supports / accepts user-added CA certificates, so you can set up something like mitmproxy on your computer, tunnel your phone's traffic through that, and extract the ccHash key data from the server response. You can then add that hash through the "Base64-encoded PassHash key string" option.</li>
|
||||
<li>If you already have a copy of the Nook ccHash key string (or, more general, the PassHash key string) in base64 encoding, you can either click on "Import existing keyfiles" if it's a file in b64 format, or you click on the "Base64-encoded PassHash key string" option while adding a new PassHash key.</li>
|
||||
<li>For retailers other than B&N that are using the PassHash algorihm as intended, you can click on "Adobe PassHash username & password" to enter your credentials while adding a key. This is the same algorihm as the original credit card number based key generation for B&N.</li>
|
||||
<li>Windows only: If you've successfully opened a PassHash-encrypted book in Adobe Digital Editions by entering username and password, you can dump the stored credentials from ADE.</li>
