Aspose.Slides - Apply Password Protection
It’s possible to save presentations with password protection. The Presentation class exposes theEncrypt method which sets a password for the presentation. To do this, simply pass the password to the Encrypt method and then use the Save method exposed by the Presentation class as a string to save the presentation.
Java
//Instantiate a Presentation object that represents a PPT file
Presentation pres = new Presentation();
//Setting Password
pres.getProtectionManager().encrypt("pass");
//Save your presentation to a file
pres.save(dataDir + "AsposeProtection.pptx", com.aspose.slides.SaveFormat.Pptx);
