Thank you for pointing this out. This was not my understanding. I had thought that a drm free kf8 file was not encrypted at all.
EDIT: By the way Harry. What is your source for this?
A quick search through the forums reveals this post by you (
https://www.mobileread.com/forums/sho...on#post3201155).
Your post in turn refers to this preceding post by knc1 who I view as an expert on these matters.

Perhaps I am wrong, but I did not interpret knc1's post as saying all kf8's including those without drm were encrypted. In fact, the excerpt from the log which he included in his post related to the decryption of ASIN B00GCIN0OM, an ebook entitled "The Contact Episode One" by Albert Sartison. This book is the first in a series and is available for free. Nevertheless, it is clearly encumbered with DRM. I can't see knc1 proffering a log file from the decryption of a drm infested kf8 file as proof that kf8 files not infested with drm are encrypted. I think the point he was making is slightly different. (Of course, it is possible though I don't think likely that the book concerned was not encumbered with drm at the time of decryption but was nevertheless encrypted).
Do you have another source? If not, I think we need some clarification from kfc1 or someone else with more knowledge than either of us on this topic. As things stand I tend to think that, unlike kfx files, kf8 files without drm are unencrypted.
