You can't create encrypted workbooks, if that is what you want to do.

The component uses the System.IO.Packaging API and I don't think it supports encrypted xlsx files.

You can protect a worksheet using a password (Worksheet.Protection.SetPassword method), but that only locks cells, hide formulas etc, for locked cells.
