using Syncfusion.Presentation;
//Open an existing presentation
using FileStream inputStream = new FileStream("Template.pptx", FileMode.Open, FileAccess.Read);
using IPresentation presentation = Presentation.Open(inputStream);
//Encrypt the presentation with a password
presentation.Encrypt("syncfusion");
//Save the presentation
using FileStream outputStream = new FileStream("Result.pptx", FileMode.Create, FileAccess.ReadWrite);
