363 performance too much. It is intended for use by the generic CCM
364 and GCM drivers, and other CTR or CMAC/XCBC based modes that rely
365 solely on encryption (although decryption is supported as well, but
366 with a more dramatic performance hit)
367
368 Instead of using 16 lookup tables of 1 KB each, (8 for encryption and
369 8 for decryption), this implementation only uses just two S-boxes of
370 256 bytes each, and attempts to eliminate data dependent latencies by
371 prefetching the entire table into the cache at the start of each
372 block. Interrupts are also disabled to avoid races where cachelines
373 are evicted when the CPU is interrupted to do something else.

556 the TEA algorithm to address a potential key weakness
557 in the TEA algorithm.

594
595 Designed for fast and secure disk encryption, especially on
596 CPUs without dedicated crypto instructions. It encrypts
597 each sector using the XChaCha12 stream cipher, two passes of
598 an ε-almost-∆-universal hash function, and an invocation of
599 the AES-256 block cipher on a single 16-byte block. On CPUs
600 without AES instructions, Adiantum is much faster than
601 AES-XTS.
602
603 Adiantum's security is provably reducible to that of its
604 underlying stream and block ciphers, subject to a security
605 bound. Unlike XTS, Adiantum is a true wide-block encryption
606 mode, so it actually provides an even stronger notion of
607 security than XTS, subject to the security bound.

632 Bernstein and further specified in RFC7539 for use in IETF protocols.
633 This is the portable C implementation of ChaCha20. See

635
636 XChaCha20 is the application of the XSalsa20 construction to ChaCha20
637 rather than to Salsa20. XChaCha20 extends ChaCha20's nonce length
638 from 64 bits (or 96 bits using the RFC7539 convention) to 192 bits,
639 while provably retaining ChaCha20's security. See

873 IV, making low entropy IV sources more suitable for block
874 encryption.
875
876 This driver implements a crypto API template that can be
877 instantiated either as an skcipher or as an AEAD (depending on the
878 type of the first template argument), and which defers encryption
879 and decryption requests to the encapsulated cipher after applying
880 ESSIV to the input IV. Note that in the AEAD case, it is assumed
881 that the keys are presented in the same format used by the authenc
882 template, and that the IV appears at the end of the authenticated
883 associated data (AAD) region (which is how dm-crypt uses it.)
884
885 Note that the use of ESSIV is not recommended for new deployments,
886 and so this only needs to be enabled when interoperability with
887 existing encrypted volumes of filesystems is required, or when
888 building for a particular system that requires it (e.g., when
