| Adiantum is a tweakable, length-preserving encryption mode |
| designed for fast and secure disk encryption, especially on |
| CPUs without dedicated crypto instructions. It encrypts |
| each sector using the XChaCha12 stream cipher, two passes of |
| an ε-almost-∆-universal hash function, and an invocation of |
| the AES-256 block cipher on a single 16-byte block. On CPUs |
| without AES instructions, Adiantum is much faster than |
| AES-XTS. |
| |
| Adiantum's security is provably reducible to that of its |
| underlying stream and block ciphers, subject to a security |
| bound. Unlike XTS, Adiantum is a true wide-block encryption |
| mode, so it actually provides an even stronger notion of |
| security than XTS, subject to the security bound. |

| help |
| Encrypted salt-sector initialization vector (ESSIV) is an IV |
| generation method that is used in some cases by fscrypt and/or |
| dm-crypt. It uses the hash of the block encryption key as the |
| symmetric key for a block encryption pass applied to the input |
| IV, making low entropy IV sources more suitable for block |
| encryption. |
| |
| This driver implements a crypto API template that can be |
| instantiated either as an skcipher or as an AEAD (depending on the |
| type of the first template argument), and which defers encryption |
| and decryption requests to the encapsulated cipher after applying |
| ESSIV to the input IV. Note that in the AEAD case, it is assumed |
| that the keys are presented in the same format used by the authenc |
| template, and that the IV appears at the end of the authenticated |
| associated data (AAD) region (which is how dm-crypt uses it.) |
| |
| Note that the use of ESSIV is not recommended for new deployments, |
| and so this only needs to be enabled when interoperability with |
| existing encrypted volumes of filesystems is required, or when |
| building for a particular system that requires it (e.g., when |
| the SoC in question has accelerated CBC but not XTS, making CBC |
| combined with ESSIV the only feasible mode for h/w accelerated |
| block encryption) |

| |
| ChaCha20 is a 256-bit high-speed stream cipher designed by Daniel J. |
| Bernstein and further specified in RFC7539 for use in IETF protocols. |
| This is the portable C implementation of ChaCha20. See also: |

| |
| XChaCha20 is the application of the XSalsa20 construction to ChaCha20 |
| rather than to Salsa20. XChaCha20 extends ChaCha20's nonce length |
| from 64 bits (or 96 bits using the RFC7539 convention) to 192 bits, |
| while provably retaining ChaCha20's security. See also: |
| <https://cr.yp.to/snuffle/xsalsa-20081128.pdf> |

| XChaCha12 is XChaCha20 reduced to 12 rounds, with correspondingly |
| reduced security margin but increased performance. It can be needed |
| in some performance-sensitive scenarios. |
