Michael Weghorn f26084217a weld: Move weld::Button to own header/Rename weld.hxx
In the past, weld.hxx used to contain the class
definitions for weld::Widget and all subclasses.

By now, weld::Widget and almost all subclasses have
been moved to separate headers, to make it easier
to keep the overview and to avoid having to
recompile ~all UI code when one class changes.

By now, only weld::Button is left in weld.hxx.
Rename the header to Button.hxx.
Drop weld.hxx includes and instead add Button.hxx
includes (or weld::Button forward declarations) where
weld::Button is used.
(Don't simply replace all weld.hxx includes with
Button.hxx ones, since many of them were for the
use of other widgets that have since been moved
to their own headers.)

Add further includes where needed now that the
(direct or transitive) includes of weld.hxx were removed.

Document Signing

Introduction

This code provides dialogs, and infrastructure wrapping libxmlsec and gpgme that implements document signing.

For signing a document, a personal key pair is used, which consists of a private key and a public key, which is added to the document in addition to the digital signature of the document, when signing it.

The document signing can be done both for the source ODF/OOXML files and the exported PDF files. It is also possible to sign existing PDF files.

Module Contents

  • doc: OpenDocument workflow legacy information with some illustrations to have an idea of the workflow, for starters check doc/OpenDocumentSignatures-Workflow.odt.
  • inc: Headers to a subset of source files inside the module, parts like source/framework have headers inside the folder.
  • qa: Unit tests for signing and shell scripts for certificates creation for testing.
  • test_docs: Documents & certificates used for testing.
  • source: More on that below.
  • uiconfig: User interface configuration for different dialogs, it is recommended to navigate from relevant source file to the .ui file linked in the class which will be under uiconfig/ui.
  • util: UNO passive registration config for GPG/ NSS.

Source Primary Contents

  • component: Main implementation of DocumentDigitalSignatures where the interaction with security environment and certificates occur.
  • dialogs: Certificate & Signatures management dialogs.
    • certificatechooser: Dialog that allows you to find and choose certificates or signatures for encryption.
    • certificateviewer: More detailed information about each certificate.
    • digitalsignaturesdialog: Main window for signatures of the documents and the start point of signing document.
  • framework: Various elements for verifying signatures and running security engine.
  • gpg: The implementation of encrypting with GPG and security environment initialization.
  • helper: Some helper classes that include signatures manager and the helpers for PDF signing, UriBinding, and XML signatures. It also include helper tools for XSecurityEnvironment.
  • xmlsec: XML, NSS, MSCrypt encryption/ signing tools, more on the low-level side of actual implementation of algorithms.

PDF Testing

To test the signed PDFs, one can use the pdfverify in this way:

./bin/run pdfverify $PWD/xmlsecurity/qa/unit/pdfsigning/data/2good.pdf

The file parameter should be an absolute path.

This is the output of pdfverify for 2good.pdf:

verifying signatures
found 2 signatures
signature #0: digest match? 1
signature #0: partial? 0
signature #1: digest match? 1
signature #1: partial? 0
