package main

)

func main() {
	data := "Hello, Ethereum!"

	// Create a new Keccak-256 hash object
	hash := sha3.NewLegacyKeccak256()

	// Write data to the hash object
	hash.Write([]byte(data))

	// Get the final hash sum
	hashSum := hash.Sum(nil)

	// Print the hash as a hexadecimal string
	fmt.Printf("Keccak256 Hash: %x\n", hashSum)
