List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , To: dm-crypt@saout.de Hi all, I'm hoping to get directions with a 'small' recovery task. Given a partition that's known to be a broken LUKS one, lhdr is missing (incl magic, chipher, hash, uuid, etc.), however there are some facts known: - chipher: aes-cbc-essiv:sha256 - keysize: 256 bits - offset: 2056 sectors - most importantly: we have the master key file available. I have the suspicion that the first approx 10% of the partition have been overwritten with random data. What are the chances of recovering any data in the given scenario? Thanks in advance, mB
