LibreOffice has builtin support for working with encrypted documents since a long time (with some recent improvements adding OpenPGP support). Further support for more fine-grained control of what a user can do with access-restricted documents was though missing. Come and see what recent improvements we implemented for LibreOffice 6.4 and 6.5, to permit fine-grained access controls to individual LibreOffice documents, matching the feature set of MS Rights Management Solution.
