Signed PDF document exported by LibreOffice (Writer) signature seems to be OK when verified e.g. by poppler pdfsig utility. However Adobe Reader (used to make sure the exported document is correct for mainstream users utilizing mainstream apps, or rather correct then opened in THE PDF reader app) successfully verifies the signature, but claims that the document was modified after signing. This does not happen e.g. for some randomly chosen PDF document released and signed by the (our) government. The problem is unaffected by changing "normal" to archive PDF/A (either 2b or 1b) PDF export option (other options left default). LiberOffice version: 6.4.3.2 (build 6.4.3-1) (but it's a long-term problem, the same problem was months or years ago) Adobe Reader version: 11.0.10 (for Windows, running in Wine) OS: Arch linux</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
