Hi team, I am encrypting my partition using dm-integrity and dm-crypt utility. I am trying to corrupt my encryted partition using dd command utiltity as below /factory/ is a mounted point of encrypted partition (/dev/mapper/factory-integrity-crypt) dd if=/security/file.txt of=/factory/file.txt bs=512 seek=8 I am able to see my file.txt content using cat command I am trying to corrupt the file content by writing to physical layer of the encrypted partition using below command dd if=/security/file.txt of=/dev/mmcblk0p5 bs=512 seek=8 /dev/mmcblk0p5 is the physical layer of the encrypted logical layer (/dev/mapper/factory-integrity-crypt) When I open the file , the file content is not corrupted and even I can unmount and mount the partition again even if I corrupt the physical block device of encrypted partition. Is this behaviour is expected? Please provide your input.
