In this simple topic, we will walk you through how to secure PowerPoint presentation using Python by password protection. A presentation can be secured in many ways including applying a watermark, adding a signature, or making it read-only. In this step-by-step guide, we’ll show you how to secure PowerPoint presentation in Python using a password with no dependence on MS PowerPoint.

Steps to Secure PowerPoint Presentation in Python

1. Configure the environment to use Aspose.Slides for Python via .NET for securing the presentation
2. Add a reference to aspose.slides namespaces in your project to password protect the presentation in Python
3. Initiate a Presentation class instance to load an existing or create a new presentation
4. Use the Encrypt method of ProtectionManager class to secure the presentation with a password
5. Save the password protected presentation on the disk

The above simplified steps ensure securing PPTX in Python using a few lines of easily understandable code. The process will commence by setting up the environment which is then followed by loading either the source presentation from the disk or creating a new one from scratch. The presentation is then secured by applying the password on the presentation using the ProtectionManager class instance before saving that on the disk as a password protected presentation.

Code to Secure PowerPoint Presentation in Python

In the above simple code, we have learnt to password protect PPTX using Python. The API is not limited only to password protection but you can also unlock and lock PPTX file in Python using an easy API interface to serve the purpose.

In this topic, we have focused on implementing PPTX security in Python by applying a password. If you are interested to learn about adding an image watermark to the presentation, refer to the article on how to add Image Watermark in PPTX using Python.
