+ 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.
+
+ If unsure, say N.

+ * Adiantum is a tweakable, length-preserving encryption mode designed for fast
+ * and secure disk encryption, especially on CPUs without dedicated crypto
+ * instructions. Adiantum encrypts each sector using the XChaCha12 stream
+ * cipher, two passes of an ε-almost-∆-universal (εA∆U) hash function based on
+ * NH and Poly1305, and an invocation of the AES-256 block cipher on a single
+ * 16-byte block. See the paper for details:
+ *
+ * Adiantum: length-preserving encryption for entry-level processors
+ * (https://eprint.iacr.org/2018/720.pdf)
+ *
+ * For flexibility, this implementation also allows other ciphers:
+ *
+ * - Stream cipher: XChaCha12 or XChaCha20
+ * - Block cipher: any with a 128-bit block size and 256-bit key
+ *
+ * This implementation doesn't currently allow other εA∆U hash functions, i.e.
+ * HPolyC is not supported. This is because Adiantum is ~20% faster than HPolyC
+ * but still provably as secure, and also the εA∆U hash function of HBSH is
+ * formally defined to take two inputs (tweak, message) which makes it difficult
+ * to wrap with the crypto_shash API. Rather, some details need to be handled
+ * here. Nevertheless, if needed in the future, support for other εA∆U hash
+ * functions could be added here.
