/**
|
|
* Skein interface. The Skein specification defines three main
|
|
* functions, called Skein-256, Skein-512 and Skein-1024, which can be
|
|
* further parameterized with an output length. For the SHA-3
|
|
* competition, Skein-512 is used for output sizes of 224, 256, 384 and
|
|
* 512 bits; this is what this code implements. Thus, we hereafter call
|
|
* Skein-224, Skein-256, Skein-384 and Skein-512 what the Skein
|
|
* specification defines as Skein-512-224, Skein-512-256, Skein-512-384
|
|
* and Skein-512-512, respectively.
