This sample focuses on the encryption and decryption of an Excel 2007, Excel 2010, Excel 2013 and Excel 2016 workbook using Essential XlsIO.
Encryption is a method of protecting workbook data.It is based on a password that converts the data into a form that cannot be understood; it also restricts anonymous users from accessing a document. Decryption is the process of converting encrypted data back into its original form so that data can be read from the workbook.
A password for encrypting a workbook can be set in Microsoft Excel 2007, Excel 2010 and Excel 2013 through the Office Menu->Prepare->Encrypt Document command.
Note: Password protection of a workbook file is different from the workbook structure and window protection you can set in the Review->Protect Workbook
