Why does saving a Writer Document remove signatures?
After finally getting LibreOffice to find my digital certificates by starting it via Terminal (please fix that already), I digitally signed my document.
Then I wanted to save it and got:
Saving will remove all existing signatures. Do you want to continue saving the document?
Why? Why does this happen? What logic am I missing? What is the purpose of not being able to save a document WITH a digital signature attached to it?
Just consider it's not only you who could modify a document - thus you won't be happy, if anybody could change your file and legally bind you to pay an arbitrary amount of money (or any other obligation) based on a document digitally signed by you. As with real paper, you need to sign a changed and legally binding document again.
