Like, sending logs to Adobe's server about what other books from other places or that are DRM-Free that you have, sending unnecessary extra data in an attempt to "market" to the user with ads, sending info to Google Analytics about your books and use of them or your computer as a whole, etc?

I might upset some of the people who get annoyed anytime privacy is brought up with those questions, but I hope you don't take offence to questions like these as I truly do appreciate you putting out a tool like this for the community! Just wondering how closely, if at all, it tries to emulate what Adobe does in this area.

If you are so concerned, perhaps you should take a look at the source code for the plugin (it's all in the .zip file you can download from the first message in this thread).

As far as I could tell, the one time I browsed through the code, it does not have the send a mass of data to Adobe functionality that was noted in ADE 4.0 though I'm not even in the running for world's greatest Python programmer so someone else may have noticed something that I didn't.

The plugin doesn't contain any of the spyware code. It only sends what's needed to get the book download (or book return, if and only if you do attempt to return a book) to work.

The only thing it does just to behave more like ADE that wouldn't be strictly necessary is a so-called fulfillment notification that lets the book distributor (so the shop where you bought your book, not Adobe) know you just downloaded that particular book. If you want, you can also disable that through the plugin settings.

The plugin does not have any code that sends anything to anywhere that's not related to the one book you're currently downloading, it doesn't send or receive any ad-related data or any other data from your computer, and it doesn't send anything to Google Analytics or other trackers.

The code is open-source and not that large, so you can easily check the source code on Github - even for Python noobs it should be easy to confirm that there's no user data tracking in there except what's needed for the book download.

Thanks for your answers! Again, no intentions of grilling you or second-guessing anything you've done. Only asked because it's Adobe we're dealing with lol.

The problem with that statement is that we are not dealing with Adobe. The whole idea of the the DeACSM plugin is to remove ADE from the equation.

Adobe is still getting paid so probably will not care.

I had this plugin working very well in my Ubuntu 21.10 and Calibre 5.41.
Now with Ubuntu 22.04 and Calibre 5.41 I get this error:

Thanks for reporting this.
This is caused by the openssl 3.0 update which is apparently included in Ubuntu 22.04. My plugin comes with oscrypto 1.2.1 which does not yet support openssl 3.0 apparently (Bug report: https://github.com/wbond/oscrypto/issues/55 )

According to that bug report, this issue has been fixed with oscrypto 1.3.0 which was released in March, so in the next update I'm going to switch to oscrypto 1.3.0 and then that error should hopefully be gone.

qfwfq · 05-01-2022, 03:43 AM

Thanx,
I'm looking forward for it as your plugin avoid me switching to Windows every time I get a book from my library

Leseratte_10 · 05-01-2022, 10:18 AM

@qfwfq I've built a test version of my plugin with support for Ubuntu 22.04, but I don't have a VM with 22.04 set up so it's untested. It still works on my 20.04 machine so at least it didn't break stuff.

Would you mind testing it and tell me if it works?

EDIT: Removed test version as it's still broken.

I just discovered this thread and this plugin and wanted to thanks Leseratte_10 for it. I can finally stop using ADE. What an horrible software lol. I'm now considering reinstalling Linuxmint on my computer!

That's going to be annoying. Looks like OpenSSL 3 (which is used in Ubuntu 22.04) dropped support for the ancient encryption methods Adobe is using in ADE.

I'll have to check if these can somehow be enabled through the plugin or if it would need additional system changes...

I believe most of those encryption methods are still available but you need to load the legacy provider which is not loaded by default. One of the people I work with also learned that if you enable the legacy provider, you have to explicitly enable the default provider as well.

Leseratte_10 · 05-01-2022, 03:53 PM

I believe that's already happening with oscrypto, if I'm reading this code correctly: https://github.com/wbond/oscrypto/bl...bcrypto.py#L45

I'll set up a 22.04 VM asap so I can test and verify this myself and attempt a couple workarounds.

Leseratte_10 Groupie Posts: 182 Karma: 2010542 Join Date: Sep 2021 Device: PB Era, PB InkPad 3 Pro	The plugin doesn't contain any of the spyware code. It only sends what's needed to get the book download (or book return, if and only if you do attempt to return a book) to work. The only thing it does just to behave more like ADE that wouldn't be strictly necessary is a so-called fulfillment notification that lets the book distributor (so the shop where you bought your book, not Adobe) know you just downloaded that particular book. If you want, you can also disable that through the plugin settings. The plugin does not have any code that sends anything to anywhere that's not related to the one book you're currently downloading, it doesn't send or receive any ad-related data or any other data from your computer, and it doesn't send anything to Google Analytics or other trackers. The code is open-source and not that large, so you can easily check the source code on Github - even for Python noobs it should be easy to confirm that there's no user data tracking in there except what's needed for the book download.
