Social DRM on decrypted KFX?

cloudbug · Today, 12:58 AM

Do decrypted KFX ebooks have watermarks of any kind? I know AZW3 had one, which could be deleted by clicking an option in DeDRM. Is this still the case? I ask because there's random text in the .xhtml files on the converted EPUB, for example. It reads fine, though.

Do you have an example of the random text? As near as I can tell in a quick and dirty test with 4 decrypted KFX files downloaded from 2 Amazon accounts (download using the Amazon Microsoft Kindle app and decrypted with Sats' tool), there are no differences in the text files.

The first .xhtml file is called Iifn8Nc-S0W3SA89oHVLoA*-right.xhtml, and the others are called similarly with some changes in the number (*).

I'm also wondering if, if not the text, maybe the images are watermarked?

Amazon puts a watermark in the OPF file. At least they did with KF8.
