  2. Disk encryption theory - Wikipedia

    en.wikipedia.org/wiki/Disk_encryption_theory

    The Adiantum scheme used in low-end Android devices specifically chooses NH, 256-bit Advanced Encryption Standard (AES-256), ChaCha12, and Poly1305. The construction is tweakable and wide-block. It requires three passes over the data, but is still faster than AES-128-XTS on a ARM Cortex-A7 (which has no AES instruction set). [24]

  3. BitLocker - Wikipedia

    en.wikipedia.org/wiki/BitLocker

    By default, it uses the Advanced Encryption Standard (AES) algorithm in cipher block chaining (CBC) or "xor–encrypt–xor (XEX)-based Tweaked codebook mode with ciphertext Stealing" (XTS) mode [1] with a 128-bit or 256-bit key. [2] [3] CBC is not used over the whole disk; it is applied to each individual sector. [3]

  4. Block size (cryptography) - Wikipedia

    This should be acceptable for up to 2 64 × 16 B = 256 exabytes of data, and would suffice for many years after introduction. The winner of the AES contest, Rijndael, supports block and key sizes of 128, 192, and 256 bits, but in AES the block size is always 128 bits. The extra block sizes were not adopted by the AES standard.

  6. Advanced Encryption Standard - Wikipedia

    en.wikipedia.org/wiki/Advanced_Encryption_Standard

    AES is a variant of Rijndael, with a fixed block size of 128 bits, and a key size of 128, 192, or 256 bits. By contrast, Rijndael per se is specified with block and key sizes that may be any multiple of 32 bits, with a minimum of 128 and a maximum of 256 bits. Most AES calculations are done in a particular finite field.

    en.wikipedia.org/wiki/Block_cipher

    Adopted by NIST in 2001, AES has a fixed block size of 128 bits and a key size of 128, 192, or 256 bits, whereas Rijndael can be specified with block and key sizes in any multiple of 32 bits, with a minimum of 128 bits. The block size has a maximum of 256 bits, but the key size has no theoretical maximum. AES operates on a 4×4 column-major ...
