Whereas add_crypto Cryptsetup should recognize all header variants, except legacy cipher chains using LRW encryption mode with 64 bits encryption block (namely Blowfish in LRW mode is not recognized, this is limitation of kernel crypto API). LUKS2 (an on-disk format) online reencryption is an optional extension to allow a user to change the data reencryption key while the data device is available for use during the whole reencryption process. The current default in the distributed sources is "aes-cbc-essiv:sha256 Cryptsetup-reencrypt reencrypts data on LUKS device in-place. debian. Unlike selectively encrypting non-root filesystems, an encrypted root filesystem can conceal information such as which programs are installed, the usernames of all user accounts, and common data-leakage vectors such as mlocate and /var/log/. For lost/deleted partitions or deleted files from a FAT or NTFS file system, try TestDisk first - it's usually faster and TestDisk can retrieved the original file names. If you are going to modify documentation, please make sure not to modify manual TPM seal command allows to encrypt data using the SRK key in the TPM chip.
