VeraCrypt is a free and open-source utility for on-the-fly encryption (OTFE). [5] The software can create a virtual encrypted disk that works just like a regular disk but within a file. It can also encrypt a partition [6] or (in Windows) the entire storage device with pre-boot authentication. [7] VeraCrypt is a fork of the discontinued ...
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 Superseded by the more secure XTS mode due to security concerns. [122] XTS: XEX-based Tweaked CodeBook mode (TCB) with CipherText Stealing (CTS), the SISWG (IEEE P1619) standard for disk encryption.
Block cipher-based encryption modes used for full disk encryption are not authenticated encryption themselves because of concerns of the storage overhead needed for authentication tags. Thus, if tampering would be done to data on the disk, the data would be decrypted to garbled random data when read and hopefully errors may be indicated ...
Some disk encryption systems, such as VeraCrypt, CipherShed (active open source forks of the discontinued TrueCrypt project), BestCrypt (proprietary trialware), offer levels of plausible deniability, which might be useful if a user is compelled to reveal the password of an encrypted volume.
BitLocker and other full disk encryption systems can be attacked by a rogue boot manager. Once the malicious bootloader captures the secret, it can decrypt the Volume Master Key (VMK), which would then allow access to decrypt or modify any information on an encrypted hard disk.
However, the first stage bootloader or an EFI system partition cannot be encrypted (see Full disk encryption#The boot key problem). [ 14 ] On mobile Linux systems, postmarketOS has developed osk-sdl to allow a full disk encrypted system to be unlocked using a touch screen.
With full disk encryption, the entire disk is encrypted (except for the bits necessary to boot or access the disk when not using an unencrypted boot/preboot partition). [8] As disks can be partitioned into multiple partitions, partition encryption can be used to encrypt individual disk partitions. [9]
VeraCrypt (a successor to a discontinued TrueCrypt), an on-the-fly disk encryption software for Windows, Mac and Linux providing limited deniable encryption [18] and to some extent (due to limitations on the number of hidden volumes which can be created [16]) plausible deniability, without needing to be installed before use as long as the user ...
