Contract 'Gpg4all' 2015

Goals

• Maintenance and development of Gpg4win: Adapt it to new versions of Windows and Outlook. Consider current cryptographic recommendations. Integrate GnuPG 'modern'. Clean up Kleopatra.
• Research: How can GpgOL do MIME? How can the existing implementation be made more secure?
• Research: How could GnuPG and email/file end-to-end security be brought to webbrowsers and android devices?

Timeline and Results

Scheduled contract time line: October 2015 - October 2017

Resulting software improvements or software designs will be developed within the upstream Free Software initiatives and thus be reflected in their roadmaps like Gpg4win/Roadmap.

Parts of the research will be done in public, using this wiki for instance. The full documents to complete the contract will be in German. It is planned (but not guaranteed) to publish them under a CC-BY-SA license.

During FrOSCon (August 2016) the BSI published the following studies (in German):

• Nutzung von OpenPGP auf Android
• Nutzung von OpenPGP in Webanwendungen

Workpackages

• WP1.1: GpgOL
  • Feasibility study: MIME support for MS Outlook
  • Feasibility study: Exchange support for MS Outlook
  • 64-bit version of GpgOL for MS Outlook 2010/2013/2016
  • Test plan
• WP1.2: Improve Kleopatra
  • Initial setup dialog
  • Initialization of OpenPGP smart cards
  • Associate file extensions with Kleopatra
  • Auto import of missing certificates
  • Easier setting of owner trust after import
  • Improvements in several certificate related function and dialogs, e.g.
    • Creation of revocation certificates

  • Description of available Android implementations using OpenPGP
  • Recommendations, including effort estimation and risks when improving an existing Free Software implementation or developing a new one.

Principal BSI

In 2015 the German Federal Office for Information Security (BSI) contracted Intevation and g10 Code for the 'Gpg4all' project. The public tender was published in April, work started in October.

Team

The German companies Intevation GmbH and g10 code GmbH are the main technical drivers behind Gpg4win and GnuPG. For the tasks at hand they have secured additional expertise and help by the following subcontractors:

• Thomas Oberndörfer (Mailvelope GmbH)
• Dominik Schürmann (TU Braunschweig, OpenKeychain)
• Vincent Breitmoser (OpenKeychain)
• Oskar Hahn
• KDAB (Deutschland) GmbH & Co. KG
