Since that operates on the Writer-internal text representation (string used being the Writer node's plain text content), that might be very hard for non-LibreOffice programs to verify?
The idea is that per-paragraph signature should be non-chained, similar to per-document signatures, so the Writer field(s) representing the signature(s) should be filtered out before hashing, but otherwise this just takes the paragraph text as-is. (My understanding is that ODF specifies what is the exact paragraph string for a <text:p> element.) So this is work in progress, the plan is that before -6-0 branchoff any Writer-internal placeholder character (like field start/end, at-char anchor character) will be filtered out (before hashing). I hope that addresses your concern. :-) Regards, Miklos
