	  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.

	  This is a generic implementation of AES that attempts to eliminate

	  with a more dramatic performance hit)

	  Instead of using 16 lookup tables of 1 KB each, (8 for encryption and
	  8 for decryption), this implementation only uses just two S-boxes of
	  256 bytes each, and attempts to eliminate data dependent latencies by
