Is there some way to lock files with a password or to lock open files to prevent them from being edited by others?
Use case examples:
Jack wants to sell Blender models, but wants to ensure that only those who have paid and been sent a password can edit the models.
Can a password be used?
Jack and Jill are making a hill for their water simulation. However, Jack wants to make sure the hill is completed before Jill tries to run a water simulation.
(How) can he lock the file?
To be clear:
- LibreOffice (also open source) allows password protected files.
- I do not want to sell files as described, but I do want to protect my files via password sometimes (and will need to in some situations).
