Ok, whatever happened, /dev/sda6 is not a LUKS device. There is one hidden in there at offset 0x7e00 = 32256 though. Looks like there was some LVM or other wrapper around it, The crypsetup man page comments on this sutuation as follows: "But note that when the LUKS header is at a nonzero offset in a device, then the device is not a LUKS device anymore, but has a LUKS container stored in it at an offset." I am not sure how to access this. Maybe something like losetup -o 32256 /dev/loop0 /dev/sda6 would work. If cryptsetup -v isLuks /dev/loop0 woeks afterwards, than you might acces the container this way. Also note that for LUKS you do not need to specify cipher or hash (except when formating) as they are stored in the LUKS header.
