GroupDocs.Merger allows to add document password. Here are the steps to add document password:

• Initialize AddPasswordOptions class with new document password;
• Instantiate Merger object with source document path or stream;
• Call AddPassword method and pass AddPasswordOptions object to it;
• Call Save method specifying file path to save resultant document.

The following code sample demonstrates how to add document password.

string filePath = @"c:\sample.pptx";
string filePathOut = @"c:\output\result.pptx";

AddPasswordOptions addOptions = new AddPasswordOptions("SAMPLE_PASSWORD");

using (Merger merger = new Merger(filePath))
{
    merger.AddPassword(addOptions);
    merger.Save(filePathOut);
}
