Interface ShakeHash

sha3/shake.go:17–28

ShakeHash defines the interface to hash functions that support arbitrary-length output. When used as a plain [hash.Hash], it produces minimum-length outputs that provide full-strength generic security.

// produces minimum-length outputs that provide full-strength generic
// security.
type ShakeHash interface {
	hash.Hash

	// Read reads more output from the hash; reading affects the hash's
	// state. (ShakeHash.Read is thus very different from Hash.Sum.)
	// It never returns an error, but subsequent calls to Write or Sum
	// will panic.
	io.Reader

	// Clone returns a copy of the ShakeHash in its current state.
	Clone() ShakeHash
}

// NewShake128 creates a new SHAKE128 variable-output-length ShakeHash.
// Its generic security strength is 128 bits against all attacks if at
