+/**
+ * WHIRLPOOL interface.
+ *
+ * WHIRLPOOL knows three variants, dubbed "WHIRLPOOL-0" (original
+ * version, published in 2000, studied by NESSIE), "WHIRLPOOL-1"
+ * (first revision, 2001, with a new S-box) and "WHIRLPOOL" (current
+ * version, 2003, with a new diffusion matrix, also described as "plain
+ * WHIRLPOOL"). All three variants are implemented here.
+ *
+ * The original WHIRLPOOL (i.e. WHIRLPOOL-0) was published in: P. S. L.
+ * M. Barreto, V. Rijmen, "The Whirlpool Hashing Function", First open
+ * NESSIE Workshop, Leuven, Belgium, November 13--14, 2000.
+ *
+ * The current WHIRLPOOL specification and a reference implementation
+ * can be found on the WHIRLPOOL web page:
+ * http://paginas.terra.com.br/informatica/paulobarreto/WhirlpoolPage.html
