Something has damaged mk-digest and mk-salt info on my LUKS partition's header... I DO know the LUKS-passphrase (which is used to decrypt the master key which then decrypts the bulk-data) and according to luksDump the Key slot 0 seem aslo be alive... Is there any opportunity to retrieve the encrypted data from that partition? You can see below that Key Slot 0 Salt seems to be normal, but MK digest and MK salt is overwritten with zeros somewhere somehow..................
