I have put ability to ingest resulting "keyfiles" into my deDRM fork. As this is the first time I touched PyQT, it looks rather slapdash. Repo also has source code of the utility, while the (pre)release has a copy of executable, sans runtime. It was compiled in VS2022.
Now, I am being a little vague, both intentionally and because I suck at explaining things. Also, I was going to put in some details about its usage here, but that might go against "too detailed" rule of this thread. And I don't want to post too much on github, for no good reason. So, well. People who can guess, will guess.

Caveats/notes:
  1. Now that I am putting it out, Amazon will probably fix it soon. It is easy enough. It might still work for some books, if one preserves older dlls. How soon? No idea. Maybe longer if it stays forgotten in this thread
  2. It is too technical and probably temporary to put in upstream deDRM, IMO.
  3. Windows (x86 support) only. That is the only platform I have reliable access to.
  4. I may answer some questions about it, but not many and not for long.
sorry for the stupid question, but how to get the memdump? :P
