/**
* HAVAL interface.
*
* HAVAL is actually a family of 15 hash functions, depending on whether
* the internal computation uses 3, 4 or 5 passes, and on the output
* length, which is 128, 160, 192, 224 or 256 bits. This implementation
* provides interface functions for all 15, which internally map to
* three cores (depending on the number of passes). Note that output
* lengths other than 256 bits are not obtained by a simple truncation
* of a longer result; the requested length is encoded within the
* padding data.
*
* HAVAL was published in: Yuliang Zheng, Josef Pieprzyk and Jennifer
* Seberry: "HAVAL -- a one-way hashing algorithm with variable length
* of output", Advances in Cryptology -- AUSCRYPT'92, Lecture Notes in
* Computer Science, Vol.718, pp.83-104, Springer-Verlag, 1993.
*
* This paper, and a reference implementation, are available on the
* Calyptix web site: http://labs.calyptix.com/haval.php
*
* The HAVAL reference paper is quite unclear on the data encoding
* details, i.e. endianness (both byte order within a 32-bit word, and
* word order within a message block). This implementation has been
* made compatible with the reference implementation referenced above.
*
* @warning A collision for HAVAL-128/3 (HAVAL with three passes and
* 128-bit output) has been published; this function is thus considered
* as cryptographically broken. The status for other variants is unclear;
* use only with care.
