	const hashBuffer = await crypto.subtle.digest('SHA-256', msgBuffer); // hash the message
	const hashArray = Array.from(new Uint8Array(hashBuffer)); // convert ArrayBuffer to Array
	const hashHex = hashArray.map(b => ('00' + b.toString(16)).slice(-2)).join(''); // convert bytes to hex string
	return hashHex;
