Improve Okular digital signature support

Improve open source tooling for digital signatures

Okular is a Free Software document viewer that supports multiple file formats such as PDF and OpenDocument Format, and besides viewing allows for annotation and digital signatures. It was initially created for desktop Linux and UNIX operating systems but meanwhile has grown into a universal, vendor-neutral document tool for all platforms - including an increasing amount of mobile operating systems such as Android, postmarketOS and pureOS. Digital signatures allow people to establish the source of documents, but can also be used to enter into legally binding agreements or contracts - so having a reliable and transparent solution is important. The aim of this project is to improve the support of PDF digital signatures in Okular both from the point of view of features and usability, making it easier for users to interact with this crucial privacy and security functionality.
