I am not sure if it is good to apply the robustness principle on security functions. In those cases it might be better to be defensive and reject signatures not following the recommendation. In this case if the ByteRange does not cover the whole document there could be parts of the document that can be modified without invalidating the signature. Would it then be good to tell the user that the signature has been validated and the document is not modified even though in fact there are parts of the document for which we don't know? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to evince in Ubuntu. https://bugs.launchpad.net/bugs/1085526 Title: ubuntu pdf doc viewer will not let me sign a document Status in Poppler: Confirmed Status in evince package in Ubuntu: Triaged Bug description: Just updated in last few weeks, i think ubuntu 12.4 To sign the document i have to send it to my neighbors windows computer, open it, sign it, then send it, then I get a note from echo sign that the document was sent with my signature.
