3. Click the "Link to ADE account" button
|
||||
4. Enter your AdobeID and password, then wait a couple seconds for the success message.
|
||||
5. The settings window should now say "Authorized with ADE ID X on device Y".
|
||||
6. Click the "Export account activation data" and "Export account encryption key" buttons to export / backup your keys. Do not skip this step. The first file (ZIP) can be used to re-authorize Calibre after a reset / reinstall without using up one of your Adobe authorizations. The second file (DER) can be imported into Alf.

7. Download an EPUB ACSM file from Adobe's test library and see if you can import it into Calibre: https://www.adobe.com/de/solutions/ebook/digital-editions/sample-ebook-library.html

|
||||
IMPORTANT:
|
||||
|
||||
- I would suggest creating a new dummy AdobeID to use for Calibre so just in case Adobe detects this and bans you, you don't lose your main AdobeID.
|
||||
- Combined with that I suggest importing the DER file into the Alf plugin to make sure that losing your AdobeID doesn't also mean you'll lose access to all your eBooks. See the section "Combining with Alf" below.
|
||||
- Combined with that I suggest importing the DER file into the DeDRM plugin to make sure that losing your AdobeID doesn't also mean you'll lose access to all your eBooks.
|
||||
- This plugin doesn't yet work with PDFs. Importing an ACSM file for a PDF book will just result in the ACSM file being imported, it won't be converted into a PDF.
|
||||
- This software is not approved by Adobe. I am not responsible if Adobe detects that you're using nonstandard software and bans your account. Do not complain to me if Adobe bans your main ADE account - you have been warned.
|
||||
|
||||
## Combining with Alf
|
||||
|
||||
In order to combine this plugin with Alf, you'll need to go to Alf's settings and import the DER file you've just exported from this plugin.
|
||||
|
||||
Also, there's a small code change needed to Alf's plugin to make it work together with this one. Open up the `__init__.py` file in Alf's ZIP file and search for "file_types". You'll find a list of supported file types. Add "acsm" to that list, save the file, put it back into the ZIP file, then re-import the Alf plugin into Calibre. This is needed due to a bug in Calibre - even though this plugin converts the ACSM file into an EPUB on import, Alf still "thinks" it's an ACSM file and doesn't do anything with it. By forcing Alf to accept ACSM files it will work correctly (since it'll then notice that it's actually an EPUB).
