generateAuthHash static method

String generateAuthHash({ required String orderNumber, required String orderAmount, required String orderCurrency, required String orderDescription, required String password, })

Generate authentication hash for checkout/session token requests

Formula (as per Mobibox documentation): var to_md5 = order_number + order_amount + order_currency + order_description + merchant_pass; var hash = CryptoJS.SHA1(CryptoJS.MD5(to_md5.toUpperCase()).toString()); var result = CryptoJS.enc.Hex.stringify(hash);

This means: SHA1(MD5(toUpperCase).toString()) where MD5 is converted to hex string first

Implementation

static String generateAuthHash({
  required String orderNumber,
  required String orderAmount,
  required String orderCurrency,
  required String orderDescription,
  required String password,
}) {
  // Concatenate: order_number + order_amount + order_currency + order_description + merchant_pass
  final concatenated = '$orderNumber$orderAmount$orderCurrency$orderDescription$password';

  // Convert to uppercase
  final upperCase = concatenated.toUpperCase();

  // Calculate MD5 and convert to hex string
  final md5Hash = md5.convert(utf8.encode(upperCase));
  final md5HexString = md5Hash.toString();

  // Calculate SHA1 of the MD5 hex string
  final sha1Hash = sha1.convert(utf8.encode(md5HexString));

  // Return SHA1 as hex string
  return sha1Hash.toString();
}
