Overview

Example (Mac)

k := []byte("this is a secret key; you should generate a strong random key that's at least 32 bytes long")
buf := []byte("and this is some data to authenticate")

h := make([]byte, 32)
d := NewShake256()

d.Write(k)

d.Write(buf)

d.Read(h)

Example (Sum)

buf := []byte("some data to hash")

h := make([]byte, 64)

ShakeSum256(h, buf)
