	  Adiantum is a tweakable, length-preserving encryption mode

	  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

config CRYPTO_ESSIV

	  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)

	  Poly1305 authenticator algorithm, RFC7539.

	  Poly1305 is an authenticator algorithm designed by Daniel J. Bernstein.
	  It is used for the ChaCha20-Poly1305 AEAD, specified in RFC7539 for use
	  in IETF protocols. This is the x86_64 assembler implementation using SIMD
	  instructions.

	  RIPEMD-160 (ISO/IEC 10118-3:2004).

	  RIPEMD-160 is a 160-bit cryptographic hash function. It is intended
	  to be used as a secure replacement for the 128-bit hash functions
	  MD4, MD5 and it's predecessor RIPEMD
	  (not to be confused with RIPEMD-128).

	  It's speed is comparable to SHA1 and there are no known attacks
	  against RIPEMD-160.

	  Developed by Hans Dobbertin, Antoon Bosselaers and Bart Preneel.
