For Aspose.Slides, you need to load the password protected presentation and InvalidPasswordException is thrown upon loading a password protected presentation. You can then load the presentation in catch block using following code.

public static void TestLoadPassProtected()
{
    try
    {
        Presentation pres = new Presentation("C:\\Aspose Data\\PassPres.pptx");
    }
    catch (InvalidPasswordException e)
    {
        LoadOptions options = new LoadOptions();
        options.setPassword ("abc");
        Presentation pres = new Presentation("C:\\Aspose Data\\PassPres.pptx",options);
        boolean isEncrypted= pres.getProtectionManager().isEncrypted();
 
    }
}

In order to verify the protected PDF, I suggest you to please visit this documentation link on your end.
