 496           Adiantum is a tweakable, length-preserving encryption mode
 497           designed for fast and secure disk encryption, especially on
 498           CPUs without dedicated crypto instructions.  It encrypts
 499           each sector using the XChaCha12 stream cipher, two passes of
 500           an ε-almost-∆-universal hash function, and an invocation of
 501           the AES-256 block cipher on a single 16-byte block.  On CPUs
 502           without AES instructions, Adiantum is much faster than
 503           AES-XTS.
 504
 505           Adiantum's security is provably reducible to that of its
 506           underlying stream and block ciphers, subject to a security
 507           bound.  Unlike XTS, Adiantum is a true wide-block encryption
 508           mode, so it actually provides an even stronger notion of
 509           security than XTS, subject to the security bound.

 517           Encrypted salt-sector initialization vector (ESSIV) is an IV
 518           generation method that is used in some cases by fscrypt and/or
 519           dm-crypt. It uses the hash of the block encryption key as the
 520           symmetric key for a block encryption pass applied to the input
 521           IV, making low entropy IV sources more suitable for block
 522           encryption.
 523
 524           This driver implements a crypto API template that can be
 525           instantiated either as an skcipher or as an AEAD (depending on the
 526           type of the first template argument), and which defers encryption
 527           and decryption requests to the encapsulated cipher after applying
 528           ESSIV to the input IV. Note that in the AEAD case, it is assumed
 529           that the keys are presented in the same format used by the authenc
 530           template, and that the IV appears at the end of the authenticated
 531           associated data (AAD) region (which is how dm-crypt uses it.)
 532
 533           Note that the use of ESSIV is not recommended for new deployments,
 534           and so this only needs to be enabled when interoperability with
 535           existing encrypted volumes of filesystems is required, or when
 536           building for a particular system that requires it (e.g., when
 537           the SoC in question has accelerated CBC but not XTS, making CBC
 538           combined with ESSIV the only feasible mode for h/w accelerated
 539           block encryption)

 843
 844           RIPEMD-160 is a 160-bit cryptographic hash function. It is intended
 845           to be used as a secure replacement for the 128-bit hash functions
 846           MD4, MD5 and it's predecessor RIPEMD
 847           (not to be confused with RIPEMD-128).
 848
 849           It's speed is comparable to SHA1 and there are no known attacks
 850           against RIPEMD-160.

1195           for popular block cipher modes ECB, CBC, CTR and XTS is supported.
1196           This module should only be used for low power (router) devices
1197           without hardware AES acceleration (e.g. caam crypto). It reduces the
1198           size of the AES tables from 16KB to 8KB + 256 bytes and mitigates
1199           timining attacks. Nevertheless it might be not as secure as other
1200           architecture specific assembler implementations that work on 1KB
1201           tables or 256 bytes S-boxes.
