What's new in Gpg4win 3?

20th of September, 2017

Outlook Plugin (GpgOL)

completely overhauled:

  • Complete support for OpenPGP/MIME in MS Outlook 2010/2013/2016 (32 and 64bit). This allows to send and receive text in other languages and attachments in a proper way.
  • New user interface for encrypt/decrypt. Shows the state of encryption directly in the mail window.
  • Automatic decryption of mails (without popup).
  • Support for sending and receiving HTML emails.

Crypto-Backend (GnuPG 2.2)

  • Support of Elliptic Curve Cryptography (ECC) by integration of GnuPG 2.2.
    » Technical details about all changes in GnuPG 2.2.
  • Preparing for a better overall crypto user experience: Fetching pubkeys by default. Most users want some basic level of confidentiality for their email and file exchanges without having to deal with crypto details like distributing and checking pubkeys and their signatures. Gpg4win 3.0 provides an implementation of a concept called "Web Key Directory" (WKD, or also "Web Key Service"). By default Gpg4win tries to find and download missing pubkeys by the given email address. This behavior can be switched off, of course.
    » More Details about WKD and GnuPG configuration options ('--auto-key-retrieve' und '--auto-key-locate').
  • PGP-2 keys cannot be imported or used anymore for security reasons.
    » GnuPG 2.2: Removal of PGP-2 support.

Crypto-Manager (Kleopatra)

  • The file-encryption dialogues have been redesigned to reduce clicks and enhance the user experience.
  • Kleopatra automatically recognizes crypto-file types and executes the according action on a double-click (e.g. decrypting an encrypted file).
  • New smart-card management view.
  • New startup dialogue (if no secret key is available).
  • View on key-details has been improved.
  • Many UI- and stability improvements and additional translations.

And more

  • Added and enabled by default: a check over the internet for available updates, which will notify the user.
  • A more straight forward installation process.
  • Installation options as normal user (without administration priviledges).
  • Gpg4win compendium (German version) has been completely overhauled. We are looking for people to help us translating the changes back into English and other languages.
  • Aiming for an approval to handle governmental documents that are classified 'restricted' ('VS-NUR FÜR DEN DIENSTGEBRAUCH') by the German Federal Office for Information Security (BSI).
