Dear experts,

   I had a 500GB hard disk which was encrypted using the following specification.

type:    LUKS1

cipher:  aes-xts-plain64

keysize: 512 bits

device:  /dev/sda5

offset:  4096 sectors

size:    999708672 sectors

mode:    read/write

Pass phrase is known.

Unfortunately, the hard disk crashed sometime back. It is a hardware fault. There was no backup.

A data recovery agency managed to recover 50% of the sectors. However it is unable to recover any data as the original disk was encrypted.

So now trying to figure out how to de-crypt and recover some of the data?

I'll be extremely grateful if you can provide some answer. Thanks in advance.
