Name Hidden containers Pre-boot authentication Custom authentication Multiple keys Passphrase strengthening Hardware acceleration TPM Filesystems Two-factor authentication
  • ^  Windows 7 introduces Bitlocker-To-Go which supports NTFS, FAT32 or exFAT, however for hard drive encryption, Windows Vista and later are limited to be installable only on NTFS volumes
  • ^  BitLocker can be used with a TPM PIN + external USB key for two-factor authentication

Layering

  • Whole disk: Whether the whole physical disk or logical volume can be encrypted, including the partition tables and master boot record. Note that this does not imply that the encrypted disk can be booted off of; refer to "pre-boot authentication" in the features comparison table.
  • Partition: Whether individual disk partitions can be encrypted.
  • File: Whether the encrypted container can be stored in a file (usually implemented as encrypted loop devices).
  • Swap space: Whether the swap space (called a "pagefile" on Windows) can be encrypted individually/explicitly.
  • Hibernation file: Whether the hibernation file is encrypted (if hibernation is supported).

Modes of operation

Different modes of operation supported by the software. Note that an encrypted volume can only use one mode of operation.

  • CBC with predictable IVs: The CBC (cipher block chaining) mode where initialization vectors are statically derived from the sector number and are not secret; this means that IVs are re-used when overwriting a sector and the vectors can easily be guessed by an attacker, leading to watermarking attacks.
  • CBC with secret IVs: The CBC mode where initialization vectors are statically derived from the encryption key and sector number. The IVs are secret, but they are re-used with overwrites. Methods for this include ESSIV and encrypted sector numbers (CGD).
  • CBC with random per-sector keys: The CBC mode where random keys are generated for each sector when it is written to, thus does not exhibit the typical weaknesses of CBC with re-used initialization vectors. The individual sector keys are stored on disk and encrypted with a master key. (See GBDE for details)
  • LRW: The Liskov-Rivest-Wagner tweakable narrow-block mode, a mode of operation specifically designed for disk encryption. Superseded by the more secure XTS mode due to security concerns.[66]
  • XTS: XEX-based Tweaked CodeBook mode (TCB) with CipherText Stealing (CTS), the SISWG (IEEE P1619) standard for disk encryption.
