Whirlpool hash function
Whirlpool hash function in idiomatic Go using interfaces by the standard library. Reference:
Don't expect too much of this. There's no guarentee that this is actually safe, use at your own risk. It might delete your files if the cat in the void meows.
Examples
Checksum of a file:
f, err := os.Open("README.md")
if err != nil {
// [...]
}
defer f.Close()
h := whirlpool.New()
io.Copy(h, f)
fileHash := h.Sum(nil)
Checksum of a message:
message := []byte("Hello, world")
messageDigest := whirlpool.Sum(message)
