Combination of deACSM and deDRM creates blank pdf (DRM not removed) #40

Closed SchmidL closed 1 year ago

Bug description

hi,

I just tried, as several suggested, to use deACSM plugin in combination with DeDRM from this repo.

Unfortunately this just loaded a blank pdf, as normally happend when loading a pdf from ADE without removing the DRM.

Also the log show that a IndexError in de DeDRM: index out of range is thrown. But, When the ACSM is opend in ADE (with my Adobe ID) -> the PDF gets imported into calibre -> DeDRM removes the DRM. What not works is:

Also when I then try to redownload the fulfilled PDF from deACSM, with my Adobe ID, it cannot be opened in ADE, as E_LIC_ALREADY_FULFILLED_BY_ANOTHER_USER

I asked already the DeDRM community for help, but I think something doesn't work with deACSM https://github.com/noDRM/DeDRM_tools/issues/195

How can I help to find the bug?

Operating system

MacOS

Which version of Calibre are you running?

6.5.0

Which version of the ACSM Input plugin are you running?

v0.0.16

That's going to be tricky if it's not clear whether the issue is in my ACSM Input plugin or in the DeDRM plugin ...

So you took one ACSM file and downloaded it both through ADE and through my plugin, both authorized with the same AdobeID? Then you should have two PDF files with DRM (one from ADE and one from my plugin) that should be identical.

In an ideal world the files would be 100% identical, but they should definitely be syntactically / semantically identical.

So can you try disabling the DeDRM plugin so that it doesn't get into the way, then download the ACSM once with ADE and once with my plugin and see if the resulting PDF files are identical?

Or, if you want (since the files are encrypted anyways and unreadable for me without your key), you can also send the two files (PDF with DRM from ADE, and PDF with DRM from my plugin) to my email and I'll take a look: \<email removed> If the two files are (very) different it might be a bug with my plugin. If they are mostly identical it's probably a DRM removal issue.

I think the issue is within this plugin it'd be great if you could fix it, but I can live with using ADE in the meantime

I don't think this is an issue with my plugin. I've just downloaded this very book from archive.org and I can import it into Calibre just fine.

Are you trying to open the resulting PDF in Calibre or in ADE? This is probably an issue with DRM removal.

No further response, I'm assuming this is fixed and/or was indeed a bug with DRM removal. If not, please re-open.
