I imagine this new system is primarily aimed at reading apps, rather than dedicated reading devices.

Open source encryption is usually stronger that the closed source. But the thing is encyption works with two keys; one their side, one on ours. As long as we have our own key, it will be broken. If Apple's Fairplay isn't broken, than it would be because noone spent the effort needed.

There couldn't really be an unbreakable DRM as long as we have our own key and an encrypted ebook file. There could be DRM very hard to break, but unbreakable with a known key? Not really. Only if they also stop giving us ebook files. This is what B&N did, no? I don't really know what they did.

They made it harder for people to get the ebook file. With the current line up of their devices, you need to root them to gain access to the ebooks you purchase from B&N. For previous eink Nooks with an SD card slot there is a mod you can use which does not require root access, it sym links the directory in the system partition of the eink Nook to the SD card, so all your ebooks are downloaded to your SD card, presumably this could be done to the internal mountable partition, but it had two goals, 1) get your ebooks, 2) have more storage, and a 32gb sd card far surpasses the internal storage of the eink Nooks.

The very first Nook, and reportedly the Nook Color, have the downloaded ebooks on a user accessible partition. I'm not sure if the Nook Tablet did or not. The rest of the tablet Nooks (HD, and the Samsung line) are all locked down.

BN also removed the ability to download from their website, and neutered their Mac and PC reading apps. As far as I know the only one which is still working at anywhere near 100% is the Nook for Windows 10 app. All someone needs to do with this app is enable hidden folders in Windows 10.

It's just one of the many reasons I've given up on B&N as a source of ebooks. They seldom, if ever, have exclusive sales, and they make it a pain to read the books I purchase on anything but their device.

No one I have spoken to in digital publishing has heard about any retailer using the new DRM.

There's another one recently. I will pm you the link because I am not sure if I can post the link to Apprentice Alf here.

Edit: possibly a second one posted yesterday too. The one from the other day was a PDF downloaded using 4.5 and it wouldn't open in 2.01.

This is for everyone using ADE past 2.0.1, than dump that version ADE and move to 2.0.1.

Here's a link to the first post with the problem, and I'll add it to my post. https://apprenticealf.wordpress.com/...#comment-54849
