Features
- Hidden containers: Whether hidden containers (an encrypted container (A) within another encrypted container (B) so the existence of container A can not be established)[52] can be created for deniable encryption. Note that some modes of operation like CBC with a plain IV can be more prone to watermarking attacks than others.
- Pre-boot authentication: Whether authentication can be required before booting the computer, thus allowing one to encrypt the boot disk.
- Single sign-on: Whether credentials provided during pre-boot authentication will automatically log the user into the host operating system, thus preventing password fatigue and reducing the need to remember multiple passwords.
- Custom authentication: Whether custom authentication mechanisms can be implemented with third-party applications.
- Multiple keys: Whether an encrypted volume can have more than one active key.
- Passphrase strengthening: Whether key strengthening is used with plain text passwords to frustrate dictionary attacks, usually using PBKDF2.
- Hardware acceleration: Whether dedicated cryptographic accelerator expansion cards can be taken advantage of.
- Trusted Platform Module: Whether the implementation can use a TPM cryptoprocessor.
- Filesystems: what filesystems are supported.
- Two-factor authentication: Whether optional security tokens (hardware security modules, such as Aladdin eToken and smart cards) are supported (for example using PKCS#11)

- ↑ 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
- ↑ An external tool can be used to read the key from the TPM and then have the key passed on to dm-crypt/LUKS via the standard input
- ↑ The current situation around TrueCrypt project is controversial. On 28.05.2014 after many years of development and broad usage the open-source (although anonymous) project was suddenly stopped, and all previous official materials and complete (encrypt/decrypt) binaries were withdrawn from its website citing some "unfixed security issues" and Windows XP end of support. The technical information herein is valid only for previous versions of TrueCrypt (v7.1a and some earlier). The latest available version (v7.2) is decrypt only, its authenticity and actual reasons behind the move are unclear, and its usage is not recommended. http://www.zdnet.com/truecrypt-quits-inexplicable-7000029994/
Layering
For more details on this topic, see Encryption layer in storage stack.
- 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 used as the boot disk itself; 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
For more details on this topic, see Disk encryption theory.
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.[114]
- XTS: XEX-based Tweaked CodeBook mode (TCB) with CipherText Stealing (CTS), the SISWG (IEEE P1619) standard for disk encryption.
