	  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.

	  RIPEMD-160 should be used.

	  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.

	  This is the portable C implementation of ChaCha20.  See also:

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

	  XChaCha12 is XChaCha20 reduced to 12 rounds, with correspondingly

	  in some performance-sensitive scenarios.
