Struct Groestl256

pub struct Groestl256<P, F> { /* private fields */ }

The Grøstl-256 hash function.

The Grøstl-256 hash function can be viewed as natively defined over AESTowerField8b and isomorphically maps to BinaryField8b. The type P is the input to the update function which has to be over a packed extension field of BinaryField8b or AESTowerField8b.
