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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1085526 Title: ubuntu pdf doc viewer will not let me sign a document To manage notifications about this bug go to: https://bugs.launchpad.net/poppler/+bug/1085526/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
