class anch::crypto::SHA2< O, B, W, R, I >

SHA2 abstract class.

SHA2 contains algorithms for SHA224/256/384/512.
The children have to define the translation array and the sigma transformation functions.
The template parameters are:

O: the output size in byte
B: the treatment block size in byte
W: the word type (32 bits or 64 bits)
R: the number of round for each chunk
I: the initial state

SHA224/256/384/512 are implemented in this library.

Since: 0.1
