/**
* The Whirlpool hashing function.
*
* <P>
* <b>References</b>
*
* <P>
* The Whirlpool algorithm was developed by
* <a href="mailto:pbarreto@scopus.com.br">Paulo S. L. M. Barreto</a> and
* <a href="mailto:vincent.rijmen@cryptomathic.com">Vincent Rijmen</a>.
*
* See
* P.S.L.M. Barreto, V. Rijmen,
* ``The Whirlpool hashing function,''
* First NESSIE workshop, 2000 (tweaked version, 2003),
* <https://www.cosic.esat.kuleuven.ac.be/nessie/workshop/submissions/whirlpool.zip>

* @author Paulo S.L.M. Barreto
* @author Vincent Rijmen.
*
* @version 3.0 (2003.03.12)
*
* =============================================================================
*
* Differences from version 2.1:
*
* - Suboptimal diffusion matrix replaced by cir(1, 1, 4, 1, 8, 5, 2, 9).
*
* =============================================================================
*
* Differences from version 2.0:
*
* - Generation of ISO/IEC 10118-3 test vectors.
* - Bug fix: nonzero carry was ignored when tallying the data length
* (this bug apparently only manifested itself when feeding data
* in pieces rather than in a single chunk at once).
*
* Differences from version 1.0:
*
* - Original S-box replaced by the tweaked, hardware-efficient version.
