For some reason /dev/sda6 starts with a partition table and looks like
a correctly partitioned whole disk. Did you perhaps use dd to copy an
image of an entire disk onto your current /dev/sda6?
Anyway, if you just want to get access to copy the data elsewhere, you
can do this (as root):
losetup -o $((0x7e00)) -f --show /dev/sda6
That will display the name of the loop device it used, probably /dev/loop0.
You can then use cryptsetup to unlock /dev/loop0, and all your data should
be there. You will want to run "losetup -d /dev/loop0" to release the loop
device after you've done a luksClose.
(AFAIK, cryptsetup does not support the "--offset" option for luksOpen.
That would have been a lot simpler.)
