Protect PPTX Presentations with Python

Build Python applications that encrypt presentations or set write protection with Aspose.Slides.

Protect a PPTX Presentation with Python

Aspose.Slides for Python via .NET provides two distinct protection mechanisms. Call ProtectionManager.encrypt to encrypt a PPTX presentation and require a password to open it. Alternatively, call ProtectionManager.set_write_protection to discourage modification without encrypting the file. A user can still open a write-protected presentation and save changes to a different file.

Encrypt a PPTX Presentation - Python

with slides.Presentation("presentation.pptx") as presentation:
    presentation.protection_manager.encrypt("123123")
    presentation.save("encrypted-presentation.pptx", slides.export.SaveFormat.PPTX)

Set Write Protection on a PPTX Presentation - Python

with slides.Presentation("presentation.pptx") as presentation:
    presentation.protection_manager.set_write_protection("123123")
    presentation.save("write-protected-presentation.pptx", slides.export.SaveFormat.PPTX)

How to Protect PPTX with Python
