I am happy to announce Tumpa 0.10.0 release. Tumpa is a desktop application which allows you to create OpenPGP keys and also allows uploading them to Yubikeys with a user friendly GUI. With Tumpa, all you need is a few form inputs and few clicks, and done! No more wrangling and breaking your head with command line interface.

This version is a complete rewrite of the initial version I released around 2 years ago. With the help from Elio and his excellent team, we have a new design. Thank you OTF for providing the funding for the work.

Saptak & I decided that the code is ready to be consumed. There are still things to work on, including the UI flows. In the coming months we are going to add more features to the application to make it super useful for advanced users too.

You can create Cv25519 or RSA4096 keys via the "Generate Key" button. You can upload any key to an attached Yubikey, but remember that to use a Cv25519 key, you will need Yubikey 5.

Installation

For Linux we have an AppImage and for Apple M1/M2 devices we have a dmg. You can download them from the release page. Remember to have a look at the user guide, specially because you need to have pcscd service running on Linux.

Technologies used

This project works because we have Johnnycanencrypt , a Python module written in Rust to do OpenPGP operations (including Smartcard operations). Which in turn uses Sequoia Project for the rust library to create/manipulate OpenPGP keys.

The UI is made via QML, using PySide6. This also shows that we can have decent looking desktop applications in Python.

The AppImage and Apple dmg files are available because of briefcase project from BeeWare team.

Give feedback

Since the focus of Tumpa is on making the use of OpenPGP with smart cards user friendly and intuitive, we need a lot of feedback from the user. So, if you find issues and have other feedback to improve the application, feel free to submit [issues])(https://github.com/tumpaproject/tumpa/issues). We are also available in #tumpa channel on IRC on libera.chat server. Feel free to ping the IRC nicknames saptaks or kushal.

If you are installing Tails into a VM for testing or anything else, always remember to mark the drive as a removable USB drive. Otherwise, the installation step will finish properly, but, you will get errors like the following screenshot while booting from the drive.

The option to do so is available in the details section for the vm in virt-manager.

I wasted a few hours today while trying to get a new VM for the SecureDrop admin setup tests.
