There is a tool called caff, which is the de-facto standard when dealing with keysigning (on a large scale, e.g. after a key signing party). This tool hasn't been touch in years, is written and configured in Perl (hence cannot be read and/or maintained :smile:) and is not easy to package, because of a lot of dependencies, etc. It is not even available in our default repositories (at least for Tumbleweed). In general there seems to be a certain kind of frustration with this software, but there is no real alternative available yet.
Ideally the new toolset should allow to organize a complete keysigning party, e.g. it should assist the organizer with:
- Collecting all the keys before the keysigning party (e.g. automatically via mail and/or a dedicated OpenPGP keyserver) or by adding them manually (e.g. import the key itself or the key ID)
- Prepare a keyring/printout containing all of the keys previously collected and make it available to all participants (via mail, via keyserver, by copying it to a HTTP server, or possibly by hosting it over HTTP for ourselves, etc.)
For the actual participants of a keysigning party there should be a set of tools to allow for the following:
- Optional: Import the keyring published by the organizer
- Iterate through all of the keys (either from previously imported keyring or specified by the user):
- Retrieve the key information from a keyserver, if necessary
- Display the required information (fingerprint, name, UIDs, etc.)
- Ask the user for confirmation
- Actually sign the key
- For each UID that contains a mail address, the following should be done:
- Strip the UID from the rest of the key
- Send the receiver his signed key via mail, which makes sure he is (and/or at least was at some point in time) in control over the specified mail address
- Optional: Upload the key to a keyserver (when the mail loop is not wanted, etc.)
Another set of scripts/tools that might be useful for the organizer of a keysigning party, might allow for visualization of the web of trust before and after the event takes place. For instance the tool could generate a graph on the keyring published before the keysigning party. The resulting image file can be published. After the event has taken place and all of the participants had enough time to sign their keys (e.g. two weeks after the event), you could re-issue the command and publish the new graph. Ideally, the web of trust should be way better than beforehand.
All of this should be configurable via configuration files and command line options. It should be something easy to understand and flexible to use (e.g. YAML). You should not require any knowledge about the programming language that is used (which is the case with caff, since it uses Perl for its configuration file).
While I'm open to discussion about the programming language and tools being used, I'm planning to work on this in Go. I don't have a lot of experience with it yet, and hope to improve my skills with this project. Support for most of the requirements is already available, in particular:
- OpenPGP for actual cryptographic operations: https://godoc.org/golang.org/x/crypto/openpgp
- SMTP for sending mail(s): https://golang.org/pkg/net/smtp/
- Hosting and retrieving content via HTTP: https://golang.org/pkg/net/http/

Contribute to terraform-provider-libvirt by pinvernizzi
Description
The SUSE Manager (SUMA) teams' main tool for infrastructure automation, Sumaform, largely relies on terraform-provider-libvirt. That provider is also widely used by other teams, both inside and outside SUSE.
It would be good to help the maintainers of this project and give back to the community around it, after all the amazing work that has been already done.
If you're interested in any of infrastructure automation, Terraform, virtualization, tooling development, Go (...) it is also a good chance to learn a bit about them all by putting your hands on an interesting, real-use-case and complex project.
Goals
- Get more familiar with Terraform provider development and libvirt bindings in Go
- Solve some issues and/or implement some features
- Get in touch with the community around the project
Resources
- CONTRIBUTING readme
- Go libvirt library in use by the project
- Terraform plugin development
- "Good first issue" list
Help Create A Chat Control Resistant Turnkey Chatmail/Deltachat Relay Stack - Rootless Podman Compose, OpenSUSE BCI, Hardened, & SELinux by 3nd5h1771fy
Description
The Mission: Decentralized & Sovereign Messaging
FYI: If you have never heard of "Chatmail", you can visit their site here, but simply put it can be thought of as the underlying protocol/platform decentralized messengers like DeltaChat use for their communications. Do not confuse it with the honeypot looking non-opensource paid for prodect with better seo that directs you to chatmailsecure(dot)com
In an era of increasing centralized surveillance by unaccountable bad actors (aka BigTech), "Chat Control," and the erosion of digital privacy, the need for sovereign communication infrastructure is critical. Chatmail is a pioneering initiative that bridges the gap between classic email and modern instant messaging, offering metadata-minimized, end-to-end encrypted (E2EE) communication that is interoperable and open.
However, unless you are a seasoned sysadmin, the current recommended deployment method of a Chatmail relay is rigid, fragile, difficult to properly secure, and effectively takes over the entire host the "relay" is deployed on.
Why This Matters
A simple, host agnostic, reproducible deployment lowers the entry cost for anyone wanting to run a privacy‑preserving, decentralized messaging relay. In an era of perpetually resurrected chat‑control legislation threats, EU digital‑sovereignty drives, and many dangers of using big‑tech messaging platforms (Apple iMessage, WhatsApp, FB Messenger, Instagram, SMS, Google Messages, etc...) for any type of communication, providing an easy‑to‑use alternative empowers:
- Censorship resistance - No single entity controls the relay; operators can spin up new nodes quickly.
- Surveillance mitigation - End‑to‑end OpenPGP encryption ensures relay operators never see plaintext.
- Digital sovereignty - Communities can host their own infrastructure under local jurisdiction, aligning with national data‑policy goals.
By turning the Chatmail relay into a plug‑and‑play container stack, we enable broader adoption, foster a resilient messaging fabric, and give developers, activists, and hobbyists a concrete tool to defend privacy online.
Goals
As I indicated earlier, this project aims to drastically simplify the deployment of Chatmail relay. By converting this architecture into a portable, containerized stack using Podman and OpenSUSE base container images, we can allow anyone to deploy their own censorship-resistant, privacy-preserving communications node in minutes.
Our goal for Hack Week: package every component into containers built on openSUSE/MicroOS base images, initially orchestrated with a single container-compose.yml (podman-compose compatible). The stack will:
- Run on any host that supports Podman (including optimizations and enhancements for SELinux‑enabled systems).
- Allow network decoupling by refactoring configurations to move from file-system constrained Unix sockets to internal TCP networking, allowing containers achieve stricter isolation.
- Utilize Enhanced Security with SELinux by using purpose built utilities such as udica we can quickly generate custom SELinux policies for the container stack, ensuring strict confinement superior to standard/typical Docker deployments.
- Allow the use of bind or remote mounted volumes for shared data (
/var/vmail, DKIM keys, TLS certs, etc.). - Replace the local DNS server requirement with a remote DNS‑provider API for DKIM/TXT record publishing.
By delivering a turnkey, host agnostic, reproducible deployment, we lower the barrier for individuals and small communities to launch their own chatmail relays, fostering a decentralized, censorship‑resistant messaging ecosystem that can serve DeltaChat users and/or future services adopting this protocol

Add support for todo.sr.ht to git-bug by mcepl
Description
I am a big fan of distributed issue tracking and the best (and possibly) only credible such issue tracker is now git-bug. It has bridges to another centralized issue trackers, so user can download (and modify) issues on GitHub, GitLab, Launchpad, Jira). I am also a fan of SourceHut, which has its own issue tracker, so I would like it bridge the two. Alas, I don’t know much about Go programming language (which the git-bug is written) and absolutely nothing about GraphQL (which todo.sr.ht uses for communication). AI to the rescue. I would like to vibe code (and eventually debug and make functional) bridge to the SourceHut issue tracker.
Goals
Functional fix for https://github.com/git-bug/git-bug/issues/1024
Resources
- anybody how actually understands how GraphQL and authentication on SourceHut (OAuth2) works
Advent of Code: The Diaries by amanzini
Description
It was the Night Before Compile Time ...
Hackweek 25 (December 1-5) perfectly coincides with the first five days of Advent of Code 2025. This project will leverage this overlap to participate in the event in real-time.
To add a layer of challenge and exploration (in the true spirit of Hackweek), the puzzles will be solved using a non-mainstream, modern language like Ruby, D, Crystal, Gleam or Zig.
The primary project intent is not just simply to solve the puzzles, but to exercise result sharing and documentation. I'd create a public-facing repository documenting the process. This involves treating each day's puzzle as a mini-project: solving it, then documenting the solution with detailed write-ups, analysis of the language's performance and ergonomics, and visualizations.
