BookLive decryption

Question / bug report

Hi team, purchased a Japanese art book for my artist roommate. Trying to strip the DRM so she can read it just as a PDF.

The DeDRM plugin seems to complain "file is not a zip file" when attempting to decrypt it.

Running file on it from a Linux machine spits out

0_EB100027174500100101502021.epub: ISO Media, OMA DCF DRM Format 2.0 (OMA-TS-DRM-DCF-V2_0-20060303-A)

For fun I also tried running strings on it. There's a string that reports back application/vnd.oma.drm.dcf which seems to reinforce that it's using "OMA" (Open Media Alliance?) for its DRM method.

Is there any way I can get the DRM free version of this title, or am I better off trying to track down a Kindle or other version with "easier" DRM?

Which version of Calibre are you running?

7.22.0 (Win64)

Which version of the DeDRM plugin are you running?
