Strong encryption algorithms are not supported in syncfusion XlsIO

During sheet creation i have set password like below:

 workbook.Worksheets[1].Protect("123");
 workbook.Protect(false, true, "123");
 workbook.Version = ExcelVersion.Excel97to2003;

And trying to read as below:

ExcelEngine excelEngine = null;
IApplication application = null;
IWorkbook workbook = null;
IWorksheet sheet = null;
... ...
excelEngine = new ExcelEngine();
application = excelEngine.Excel;
workbook = excelEngine.Excel.Workbooks.Open(fileLocation, ExcelOpenType.Automatic);

But shows message like Strong encryption algorithms are not supported. I tried using

workbook = excelEngine.Excel.Workbooks.Open(fileLocation,ExcelParseOptions.Default,false,"123",ExcelOpenType.Automatic);

Even using the below code it is not working:

application.OnPasswordRequired += application_OnPasswordRequired;
void application_OnPasswordRequired(object sender, PasswordRequiredEventArgs e)
        {
            e.NewPassword = "123";
        }
