Paragraph Digital Signature question

For documentation purposes (137292 – [LOCALHELP] Add Help page on TSCP Paragraph Signature), I’m trying to activate the Paragraph Signature feature available in LO. The feature was implemented and a terse presentation is available at the bug page.

I admit I’m not familiar with the several digital signature/certificates variants, but I know there are X509 and OpenGPG types of digital signatures, both available to LO.

The feature can be accessed at Insert - Fields - More Fields - Document - Paragraph signature.

So I have questions regarding this feature:

  • Does it work with OpenPGP-type certificates?

  • If affirmative what is the visual indication we get when the paragraph is sucessfully signed?

  • If not, what certificates do I need to sign paragraphs?

  • Are there conditions to be met on certficates for signing paragraphs?

  • Is this feature working at all?

Thank you
PS. If I can collect pieces of wisdom on the topic here I’ll add to the Help as well as to the Guides.
