Still unable to decrypt AZW files.

Environment: Kindle version: 1.17 Calibre version: attempted both 5.24 and 5.26 Mac version: Big Sur 11.5.2 DRM Tools version: 7.2.1

You cannot be using Kindle for Mac 1.17 with Big Sur as it's a 32-bit program. All the information you need is in the links that @mizuOda gave above.

[2020MacOwner]

I have 1.17 loaded on another mac running Yosemite, then copy the the AZW files to the mac running the above listed versions.

[ElleKayEm]

Then that's the issue. The Kindle app the books are downloaded to and calibre with DeDRM need to be on the same machine and user.

[2020MacOwner]

They are the same user. This has been working fine for YEARS...it wasn't until Calibre 5.24 that it 'broke'.

[ElleKayEm]

Each installation of Kindle for Mac has a unique key for its books. DeDRM cannot retrieve that key from a different computer.

Good afternoon, I have Calibre 5.27 and DeDRM 7.2.1 running. I am no longer able to decrypt my azw3 books I purchase from Amazon. I have double checked the serial numbers in the plugin customization match those of the Kindle Paperwhite I am using when doing the "download and transfer via USB" option. The log file indicates "No Key Found." I have tried removing the plugin and reinstalling it. Any ideas? Thanks!

Here is the log file for reference:

@tool3884 You have chosen an E-ink Kindle (not a Fire) with "download & transfer via USB"? Be sure you have that Kindle's serial number in DeDRM's customization. Try copy and pasting the serial number from the website.

[tool3884]

@ElleKayEm Thank you for the super quick response! Yes, I made sure I am selecting my Kindle Paperwhite when I use the "download & transfer" option. I also double and triple checked the SNs match (on the device, from the Amazon Devices page, and in the Plugin). This just recently started happening. I have been using Calibre and DeDRM for years without issue and this is the first time this has happened. What I find odd is the log file says "Found 4 Keys to Try." I only have two SNs in the plugin customization option. Maybe Amazon has changed something on their end as well, I know the website has a new UI.

[ElleKayEm]

@tool3884 Still working for me. Only two things I know to try: Download a fresh copy of the book to make sure you have chosen the right device and then make sure that is the copy that you add to calibre. Copy and paste the serial number for that Kindle from your content & devices page into DeDRM to prevent typos.

More than one key is derived from each serial number. My log shows 10 keys to try when I have 3 serial numbers plus a "default_key" in the Kindle for PC section.

[tool3884]

@ElleKayEm The problem seems to be isolated to one computer. I did a fresh install of Calibre 5.27 and DeDRM 7.2.1 on a different computer and it worked without a problem. I am going to try to reinstall Calibre on the issue computer and see if it fixes the issue.
