Help with an disk image of a WD my passport with no password set

[brilliantcn]

Please excuse me for any inappropriateness as i am pretty new here.
I had a WD My Passport 1TB, of which i am not sure of the chips as the physical drive is not with me at the moment.
This WD passport was purchased around 2009(10?), and was used to contain all my work of photos from 2009 to 2012. From whatever i remember, i had never set a password to it.
It worked fine until in 2013, when i plugged the drive into a Smart TV USB port to show the photos to my wife(at this time the photos in the drive showed up perfectly). At first there were no problem. However after two or three days click sound was heard. Then it failed.
After taking it to WD designated data recovery centre, i was told that the hardware failed permanently, and when i asked them about the files, i knew for the first time that WD automatically encrypted files. but the service area could be bad, unless i could obtain the same hardware HD. Otherwise they can not get the files at all.
So i asked them to make a disk image and i have kept the disk image for the past ten years.

here is the info about the image:

I tried other disk recovery software on this image.
In fact one software gave me several files that can be rescued: some WD exes, Docs, html, and two big files.

I guess these must be the encrypted data. Of course i couldn’t possibly open these archives.

Then when i came across the Reallymine and linux-mybook-tools project. You could never imagine how excited i was when finding these projects!
So I started to use reallymine decrypt to decrypt the image, i was asked to “Enter WD password”, which i believe i never set.
I used the default Pi password, but it said “Wrong Password”

Output from The command
Reallymine dumpkeysector

Output from “Reallymine dumpfirst “

Output from “reallymine dumplast”

Then i tried to use @themaddoctor ‘s Linux Mybook Tools,

1.in Ubuntu 22.04, the 1TB image is in an NAS location and mounted as /dev/loop8,as we can see from the picture here.

2.Running command
$sudo bash findkeyblock.sh /dev/loop8

So here is the question:
how do i proceed from here? Is it any hope that these files can be recovered at all?

Any suggestions, helps and tutorials are greatly appreciated.
Thanks in advance to everyone and in particular to the wonderful @andlabs and @themaddoctor for creating wonderful programs.

Q1. Do you still have the original enclosure?
Q2. Which WD My Passport exactly do you have? WD had many models with that or similar name.

Finally i got hold of the physical disk. it was manufactured in March of 2011. and the chip was Symwave 6316 3VB14. When i dumped the service area, the dump was empty or the word "Bad", which may be why the WD service said the disk has corrupted Service Area.
Is there any other possibility of recovering data from it?
Thanks again to everyone
