I think it should be mentioned that qdigidoc4 won't work properly without opensc package installed ArkadSt (talk) 09:32, 28 June 2022 (UTC)

The latest package list opensc as optional dependency, is it enough: opensc (opensc-git) (optional) – smart card support ? --Fengchao (talk) 02:15, 27 October 2022 (UTC)

In the Belgium section it is mentioned that digital signing of pdf's could be done with okular. But signatures generated this way will be shown as invalid when checking the pdf at the Belgian government's signing box, https://signing.fts.bosa.belgium.be/. The issue is similar to the one described here https://bugs.kde.org/show_bug.cgi?id=496604. This problem is not present when using libreoffice. Libertepourmoi (talk) 21:49, 1 January 2025 (UTC)
