Commented Issue: Reading Protected Excel file throws exception [2040]

Hi,
Our users will upload a protected excel (workbook and sheet) which we convert into stream and pass it to excel data reader.
I've got the below exception from ExcelDataReader.cs (Line : 139)
"No data is available for encoding 6236."
 
Pls let me know if there is any fix for reading protected excel.
 
Thanks
Kathiravan

There is no support currently for unprotect in this library. In our application we use other third-party libraries to unprotect spreadsheets before opening them with ExcelDataReader, such as SecureBlackBox (not cheap though).
