/** |
|
* 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 |
