Crypto in general
x509: access windows certstores
Windows already has a "keystore" for x509 certificates, for some settings it would be good if this store could be read in from Gpg4win (the components dirmngr and gpgsm).
Won't happen because Microsoft controls this store and may add new certificates without notice. -- Werner Koch 2015-11-27 14:21:53
I think this might be added as an Option. While it is correct that Microsoft controls this store this is basically the baseline system trust so you might also want to use it for certificates as attacks are already possible when an attacker controls such a certificate you won't lower security but you would improve usability. -- Andre Heinecke
long shot email idea: encrypt as message/rfc822
The headers of emails may contain more information than many people would like to reveal. A standard conforming method to send these emails is to just attach the full email as message/rfc822 type and encrypt the result. Email client with MIME support will already display it. So they only missing link is to add a convention that the subject line and reciepients of the attached email will be used and display when an email is read. Would be nice to try this concept and implement it in Free Software clients like mutt, Kontact Mail, claws, (a fork of) Thunderbird.
add GnuPG as "cryptographic service provider" (CSP) and MIME/filter
see https://msdn.microsoft.com/en-us/library/aa380245.aspx, https://msdn.microsoft.com/en-us/library/bb931380.aspx. Needs more evaluation. Could possibly enable other application to access some GnuPG features.
Sorry, this is BS. We can't provide an alternative to the platforms standard encryption facilities by making our own a part of it. The overall goal is to avoid the use of proprietary code as far as possible. BTW, we actually make use of the CSP to mix in some random into our own RNG; this might be helpful but it won't harm. -- Werner Koch 2015-11-27 14:21:53
Make it easier to create of keys larger than 3072 bits?
Some people wish that Gpg4win/GPA should make it easier to create RSA keys with more than 3072bits, especially 4096 bit keys that seem to be popular for new certs in some circles. If so, it would be done in the advanced configuration "create new key" input GUI. Others believe that 2048 bit is a sane default, for the discussion see LargeKeys.
Nope. A GUI should actually not have a way to tweak parameters. This is for expert users with enough knowledge and training to evaluate their security needs. A part of that training should be the use of the command line. -- Werner Koch 2015-11-27 14:25:09

Guide first time users
When starting Kleopatra for the first time on Windows it currently starts up with an empty Window and users may felt lost or may not know what do to next. Kleopatra should give users an idea what to do next, e.g. generated a certificate or configure some keyservers.
Improved Smart Card handling
GUI for Revocation certificates
Kleopatra should allow you to generate and publish a revocation certificate for your certificates. Planned to be implemented with Gpg4all2015.
Kleopatra is KDE Software and thus available in 50 Languages. There could be optional "Language pack downloads" made available for those languages or at least for all the languages that the Gpg4win installer supports.
Better certificate selection dialog
The selection dialog could be improved. The default view should be very simple, but showing something that motivates people to look into the second and third layer of information. Ideally the display of the first two layers should be integrated in the email application.
- Layer: Just a graded information how well the fit of certificates is.
- Layer: Showing the accumulated information per email address.
- Layer: Showing the default information per email, address like encryption method, last contact via the certification, trustlevel, grade of algorithms.
- Hide untrusted (expired) keys by default and only show them on request.
Ability to decrypt files that do not have the .gpg extension in their filename
As of Feb 2014, trying to decrypt a file without the .gpg extension results in the somewhat missleading error message "Could not determine whether this is an S/MIME or an OpenPGP signature - maybe it is not a signature at all?"
Trying to import a certificate with an MD5 has signed user id fails because "gpg: Note: signatures using the MD5 algorithm are rejected", it seems this "note" is not displayed, but it should so the user can diagnose this case. post on users-list
Integration in the gpg4win build system
Currently in progress in the kleo-kf5 branch of Gpg4win.
Clipboard: Integrated Sign&Encrypt support
User may want to use the clipboard for encrypting and signing text (as it is possible with files) to be able to secure confidentiality and integrity. For a description of user problems with Gpg4win 2.2.4 see https://wald.intevation.org/forum/forum.php?thread_id=1488&forum_id=21&group_id=11.
Clipboard: Support through command line argument
You can define system wide shortcuts on Windows that start a program with some command line arguments. This could be used to create a shortcut to encrypt / decrypt your clipboard. Ideally these shortcuts would be configurable in Kleopatra itself. But it might be a cool feature for advanced users that we could document in the compendium. The time needed to implement this would be less then a day as it would be just adding some command line arguments. And a workflow that includes shortcuts to encrypt / decrypt could be useful.
Clipboard: Add support for files
Currently kleopatra only offers the clipboard options if text is in the clipboard. While tecnically this is currently necessary (as the jobs for "non-mime" mails are used in the clipboard implementation) technically there should be no reason why this shouln'd work with files too.
Support for secret keys in a different location for GpgOL and GpgEX
People may want to save their secret keys or their complete crypto setup on removable devices. While Gpg4win already supports creating a "portable" version, this version does not support GpgOL and GpgEX and it would be a plus to have the properly installed version read only the secret keys from the removable filesystem device. It is already possible using options for keyring or the GNUPGHOME environment variable, however if many people want to use this, guided support from a GUI would be an improvement.
See wald thread 1656
This list relates to GpgOL 2.0 as it will be part of Gpg4win-3.0 with full mime support etc.
For a better initial User experience GpgOL could have some more Features regarding key creation:
Initial Key creation
If Outlook is started with GpgOL active and there are no secret keys for any of the configured accounts GpgOL should detect that and offer to generate keys, taking the name and e-mail from the account settings.
If GpgOL has created a key and it is used to encrypt for some time e.g. 10 encryption GpgOL should start to nag the user to make a backup and offer to print / export the secret key. As long as the user explicitly confirmed that a backup was made. GpgOL should make it clear that you can't read your mails anymore if you loose the key or the password.
Key creation after account setup
If a new account is added and there is no private key for an account GpgOL should offer to create one.
GpgOL should support publishing a key through a Web Key Service.
Easier default configuration
The default configuration or at least a setting in GpgOL should affect trust model (tofu+pgp), auto-key-locate and auto-key-retrieve.
Improved change handling
Currently changes to categories or to flag a message is not supported while the message is in a decrypted state. There might be solutions to that which need to be investigated and tried out.
Show contents during signature verification
While verifying a signature GpgOL should already show the unverified content of the message. This is especially important if auto-key-retrieve is enabled and key retrieval takes some time.
Encryption without Kleopatra or GPA
This would have several advantages:
- GpgOL would have full control over the encryption process
- Better maintainability
- GpgOL could save used keys e.g. through the addressbook
- Showing the certificate selection as Modal Window withouth Window Management tricks
Address book integration
It should be possible in the addressbook to configure encryption keys.
GpgOL should offer opportunistic encryption (toggle encrypt/sign) if there are valid keys for all recipients.
- Checkbox for "Show Passphrase" A checkbox that disables the obfuscation of the Passphrase in the input field. This could help with the input of complex passphrases if you are sure that no one watches over your shoulder ;) See issue2139.
- Add these features also to the GTK+ Version of the Pinentry.
- Improve the native Windows passphrase which is part of the vanilla installer. For example it could be tied to the Windows taskbar, so that a user knows where to look for it. (not ideal because another pinentry-variant to maintain)
- Or create a static pinentry-qt4 binary that does not depend on the Qt DLL's and could be included in the vanilla / light installers.
- Ribbon UI for Windows 8 / Context integration. It would be nice if GpgEX would show Ribbon UI actions depending on the Explorer context.
- Shell extension for encrypted tarballs The general idea is that an encrypted tarball could be accessed as a Windows Shell data source. Something in a bit similar to what windows does with ".zip" folders. This would include drag & drop support to decrypt / encrypt and could probably even work transparently for some applications. Could be a lightweight alternative (with a platform independent data storage) to a virtual disk driver for a fully fletched encrypted disk. For an Example see The Tarfolder extension
Website / Documentation
- link the wiki (more prominently).
- Documentation: More details on adding more IDs, e.g. that Add Id only works if you have the privat certificate.
- HTML Documentation: Make it easier to click it, right now, it is way down on the page and below the download button.
- Reimplement an EmailExercisesRobot like adele to be Free Software and to handle OpenPGP/MIME. (E.g. by using Python3 and pyme/pygpgme) See old idea sketches from 2009.
- Improve the style in which "NEWS" are writting to be displayed by the website and the announcement, it should be both
- Give the refences to the issues so that interested people can go deeper. Like an issue number or a CVE or similiar.
- More written from the point of view of the users. So what does this particular entry mean for the users? What changes for them
- Werner commented about this point: Detailed information should be looked up in the GIT which has links to CVE ids, Debian and GnuPG bug ids.
- Screenshots: English ones. Windows 8.1. Explicitely state permissions like CC-BY.
- A good FAQ.
Explain the processes on Windows
.. so that people know what processes run there and why they are running. Best way would be a diagram. (For example see this wald post where a more explanation would be useful.).
Howto to make x509 root certificates trusted
- The installer should only suggest a restart as a very last resort when it is impossible to unlock all files by killing the relevant processes.
- A launch certificate manager (together with a firststart wizard in the certificate manacher) as an Option after installation would be nice.
- http://lists.wald.intevation.org/pipermail/gpg4win-users-en/2014-July/000988.html "Plea for GPG4Win vanilla installation step reduction"
- .. should work without Administration rights.
- .. should work when installed as Admin, but run as User. (possible defekt issue1801
Improved Encoding handling
- Test / fix filename problems for gpgEx with Unicode characters (e.g. issue1324)
- Fix gpgol < 2010 encoding Problems
- Proactively hunt encoding Problems and tackle them. (issue1691)
File extension handling:
Gpg4win should register file extensions like .asc .gpg .pk7 etc. and open an appropriate Software / Dialog to handle those files when they are double clicked in the Windows explorer. FWIW, gpgme now has an identify feature which works similar to file(1) by looking at the content of a file. As of now it is able to detect binary CMS message and armored PGP messages. We should extend that to binary PGP messages.
Comprehensive Video Tutorials
It would be nice to have a set of clear and short Video tutorials that explain a single use case. With the idea that you can link to those if you want to send someone a short "User friendly" explanation how they can securely communicate with you. Some ideas:
- How to generate an OpenPGP Key and distribute your public key.
- How to encrypt/sign files
- How to handle encrypted and signed files
- How to use the rudimentary Outlook 2010 / 2013 support
- Working with encrypted Text and the Clipboard.
It seems some people would benefit from an interactive walkthrough to some of the usually stages. Or an interactive question and answer session with screencast (== webinar/webworkshop? :) )
Remove necessity to reboot in the installer
The Gpg4win installer should get a proper handling of running processes and make sure that everything is killed correctly when updating / uninstalling so that the Windows 98'ish "Reboot Now" will usally not anymore happen. (May be a bad idea if we need to close the file explorer.)
Display the GnuPG engine logo more prominently
There are probably few places where the GnuPG logo should be visible in addition in Gpg4win. The idea behind this is that GnuPG can do many things and Gpg4win should point out that it is fully included and strengthen GnuPG's recognition.
Ready for distributions via app-store or digital distribution platforms?
Digital distributions platforms like Steam or the Windows v>=8.1 app-store can help with
- Updates, they may notify the user of new versions.
- Trusted downloads. Many users already trust a platform or software from the same vendor, e.g. Microsoft.
- Finding Gpg4win when searching for crypto or trust enabling applications
- Payments, if a user already has paid via a distribution platform, another payment for Gpg4win would be a small step. Users are conceptionally the best source of funding for Gpg4win. Download versions without the advantages could still be gratis.
It makes sense to check what would need to be done to distribute Gpg4win over wide spread digital distribution platforms. This usually includes a technical, a financial and a licensing/condition part that need to be clarified.
