 485           Adiantum is a tweakable, length-preserving encryption mode
 486           designed for fast and secure disk encryption, especially on
 487           CPUs without dedicated crypto instructions.  It encrypts
 488           each sector using the XChaCha12 stream cipher, two passes of
 489           an ε-almost-∆-universal hash function, and an invocation of
 490           the AES-256 block cipher on a single 16-byte block.  On CPUs
 491           without AES instructions, Adiantum is much faster than
 492           AES-XTS.
 493
 494           Adiantum's security is provably reducible to that of its
 495           underlying stream and block ciphers, subject to a security
 496           bound.  Unlike XTS, Adiantum is a true wide-block encryption
 497           mode, so it actually provides an even stronger notion of
 498           security than XTS, subject to the security bound.

 506           Encrypted salt-sector initialization vector (ESSIV) is an IV
 507           generation method that is used in some cases by fscrypt and/or
 508           dm-crypt. It uses the hash of the block encryption key as the
 509           symmetric key for a block encryption pass applied to the input
 510           IV, making low entropy IV sources more suitable for block
 511           encryption.
 512
 513           This driver implements a crypto API template that can be
 514           instantiated either as an skcipher or as an AEAD (depending on the
 515           type of the first template argument), and which defers encryption
 516           and decryption requests to the encapsulated cipher after applying
 517           ESSIV to the input IV. Note that in the AEAD case, it is assumed
 518           that the keys are presented in the same format used by the authenc
 519           template, and that the IV appears at the end of the authenticated
 520           associated data (AAD) region (which is how dm-crypt uses it.)
 521
 522           Note that the use of ESSIV is not recommended for new deployments,
 523           and so this only needs to be enabled when interoperability with
 524           existing encrypted volumes of filesystems is required, or when
 525           building for a particular system that requires it (e.g., when
 526           the SoC in question has accelerated CBC but not XTS, making CBC
 527           combined with ESSIV the only feasible mode for h/w accelerated
 528           block encryption)
