[dm-crypt] Header?

Hi everybody,

I am a bit lost now. I tried (why so ever) to connect my (ext4) 
encrypted disk to a Windows 10 System - (what a big stupid idea - I know 
- very very stupid)....

Now I can not access my encrypted disk anymore and wonder if the Header 
is damaged? My pass-phrase is absolute correct, but not accepted with 
luksOpen!


luksDump gives




blkid shows



What happened to my external disk? I am running Cent OS7...
For any help I would be so thankful!!! Really very very thankful!!!
Thanks a lot!

Kind regards,
Sumaya

Hi,

do you have pictures in there? I do not see pictures in
emails, far too many vulnerabilities in the respective 
libraries in the last few years. Can you re-send with ASCII
copies of the output?

What does parted say?

     # parted -l

Hi there,

Please resend the dumps in ASCII as Arno suggested.

Meanwhile: It seems the disk has no partition and starts with a 
LUKS-Header right away. While the LUKS-Header itself seems to be 
consistent (at first glance) the keyslot itself could of course be damaged.

Regards

-Sven

Re: [dm-crypt] Header corrupted?

[Arno Wagner]

Hi Sumaya,

that looks like you have a LUKS container on the raw disk.
Not a problem in itself, just a bit unusual. The luksDump
info looks fine. 

You can still have a problem in the key-slot. To check for 
that, please compile and run the keyslot-checker and post 
its output here. If it finds something, also post the output
with option -v, unless that is too long.

You find it in misc/keyslot_ckecker in the source-package. 
It will look for areas of possible corruption in the keyslots.

Regards,
Arno
