RSA key format is not supported #377

Question / bug report

I bought a book from a french vendor and I got a URLLink.acsm file. I've been trying to import this book into Calibre. Initially, I used Adobe ADE to import the book (through wine). At first I did an anonymous authentication. I can see the book in ADE, ADE generates a 7.5 MB epub file somewhere called "ePub made using QuarkXPress.epub". I tried opening this file with all the readers I could find, with no luck.

I then installed the DeACM plugin in Calibre. I got the account and key info. I imported all these settings into DeDRM. When I try to import my acsm file, the import doesn't work and I still can't open the book. I tried the stable and master versions of DeACM and DeDRM. It's always the same error. Here are the logs:

I believe the important line is:

ValueError: RSA key format is not supported

Could you please give me a hand? I'm willing to test and make PRs.

Which version of Calibre are you running?

6.23.0

Which version of the DeDRM plugin are you running?

v10.0.3 and master

If applicable, which version of the Kindle software are you running?

No response

Since you originally downloaded the book with an anonymous authentication, the DRM will be tied to that installation of ADE. You can read the book there? I'd try installing Windows calibre with DeDRM where ADE is installed. You'll need older calibre 4.23 and DeDRM 6.8.1.

mathesst commented 4 months ago

Hi, got the same error. I have the newest versions of DeACM and DeDRM installed in calibre. And I am getting the same error. It dosen't matter if I import the ebub or the acsm file. As from the logs I assume that DeACM is working fine, but DeDRM runs into an error of unsupported RSA Key. In my wine environment I can open the files in Adobe just fine.

DeACSM v0.0.16: Plugin returned nothing - skipping
ElleKayEm commented 4 months ago

Are ADE and DeACSM set up with the same Adobe ID? If not, then they'd have different keys. That would explain DeACSM's key not working on ADE's epub. Maybe try saving the key from DeACSM and importing it into DeDRM's customization.

mathesst commented 4 months ago

It is the same, and the last try was importing the key in DEAcm from the ADE install in Wine, which was successful (the import of the key). But still get the RSA error.

ElleKayEm commented 4 months ago

I don't know. When I've seen that error before, it was when the books had been downloaded with ADE on a different machine than the one where calibre/DeDRM was installed. Once they installed calibre/DeDRM on the machine where the books were downloaded, it worked.

mathesst commented 4 months ago

today I installed calibre on Windows and it extracted the key from ADE automatically. This Key I exported and then imported in calibre in my Linux installation. With that key I was able to decrypt the ebooks even under Linux. So there seems to be an issue between the key retrival from wine.

Yup, that what all this from the log is about:

I don't know what all you need to have installed under wine to get the key scripts to run there and get the key from ADE. Some people are able to use DeACSM to avoid using ADE. I don't know why that didn't work for you. Once you have the key in the Linux installation of calibre, DeDRM is fine because the rest of the scripts are then able to use calibre's built-in Python. With Windows calibre, DeDRM is able to also use calibre's built-in Python to run the key retrieval scripts.
