Do u really think the 39 Algorithmen are very different?

At least I don't tell people "don't try there are 39 Algorithmen, It's difficult"

Do u work in Amazon?
At least I'm not saying, "It can't be that difficult. Why doesn't somebody else do it?"

Little perspective: People have figured out then current KFX DRM twice. If you were one of the people who happened to catch the update to DeDRM right away, you were able to decrypt KFX books downloaded to the current (at that time) Kindle for PC/Mac and those downloaded directly to an E-ink Kindle with the latest firmware. By the next day we were all back to only being able to decrypt KFX files from Kindle for PC/Mac 1.26 or earlier. Whatever effort and time it took was a total waste.

The older KFX DRM encryption (which can still be removed if you can download the book with Kindle for PC/Mac 1.26 or earlier) was only figured out when Kindle for PC/Mac was updated to utilize it and more books were coming out in that format -- somewhere between 1 and 2 years after the format had already started showing up on Kindles. In other words, after a much larger amount of people were running into it.

Right now few people are even affected by this: someone who wants to buy a just published book who doesn't own an E-ink Kindle. And if you want to read it on a non-Kindle device/app, you're better off avoiding KFX and getting KF8/AZW3 anyway. I'd personally be much more interested in finding out if it's possible to get the latest Kindle for PC to cough up KF8 files.

The hardened Adobe DRM can only recently be removed after many, many years of being around but hardly utilized. That only changed when a fairly major provider of Adobe DRMed books switched completely to it.

I'd be quite surprised if KFX DRM is figured out (and the solution shared) while there are workarounds and for many it isn't even an issue. Until then, the motivation just isn't there.

In the meantime, patience, buying books elsewhere (DRM-free or which can be decrypted), and/or getting yourself some decryption knowhow.
