That's how it's intended to work. This plugin just creates the eBook file, it does not remove DRM; and Calibre cannot read / display books with DRM. If you do want to remove DRM (which would be necessary to read books with an anonymous ID at all) you'll have to download and install the DeDRM plugin, just like with books from ADE.

If you're using noDRM's fork, that should work out of the box without additional setup. If you're using Apprentice Harper's original version, you'll first need to extract the key from the DeACSM plugin and import it into the DeDRM plugin.

If this still doesn't work even with the DeDRM plugin installed (you'll need to re-import the ACSM file after installing that plugin) please post a debug log.

Ah thanks, I'll try that. Could probably clarify this in the readme (which I did read, maybe not thoroughly enough though).

Leseratte10 commented 2 years ago

The readme already mentions in the Setup script that you'll need to export the key and import that into the DeDRM plugin for DRM removal when not using noDRM's fork:

After you've activated the plugin, make a backup of the activation using the "Export account activation data". Then click "Export account encryption key" and import the resulting file into the DeDRM plugin for DRM removal. If you're using noDRM's fork of the DeDRM plugin, this step will happen automatically.

Or did you mean something else? How should that be clarified? Another sentence that Calibre can't read DRM-ed books? Let me know if you have any more issues.

Powersource commented 2 years ago

I was hoping that that step was optional and only applied if I was using one of those plugins. I think maybe it's clearer if there's an explicit: How to use: 1. ... 2. ... 3. ... right now it's more of a wall of text and it's unclear what exactly is important.

Leseratte10 commented 2 years ago

It used to be an explicit list, but now that there are four different methods to create an authorization (displayed as a list), I didn't want to have a list in a list (that would also be confusing) and re-wrote the setup instructions as they are now.

I'm going to close this issue as I assume installing the DeDRM plugin and importing the key fixed the issue, if there's still issues feel free to comment again or re-open.

Powersource commented 2 years ago

Yes it did solve it, thanks.

I think my confusion stems from that I thought what this plugin did was remove the DRM, when in fact it was sort of just the first layer of it.

Leseratte10 commented 2 years ago

Great.

Yeah, DRM removal is not what this plugin does. As that's not really 100% legal I'm not going to get involved with that. All this plugin does is take the weird ACSM download ticket file and turn it into a DRM-encrypted EPUB or PDF book so you don't need to use Adobe Digital Editions to download the book.
