HMAC Hashing for Cart Validation

public string HashWithHmac(string contentToHash)
{
	var key = Encoding.UTF8.GetBytes(_FoxyCartConfig.ApiKey);
	var sha256 = new HMACSHA256(key);
	var hashData = sha256.ComputeHash(Encoding.UTF8.GetBytes(contentToHash));
	var stringBuilder = new StringBuilder();
	foreach (var hd in hashData)
	{
		stringBuilder.Append(hd.ToString("x2"));
	}
	return stringBuilder.ToString();
