Safe software for universities & foundations

For people dedicated to researching new technology for a safer internet, it is important that these often groundbreaking ideas find their way to real-life applications.

That is why we work closely with institutes such as the Privacy by Design Foundation and iHub (Radboud University) to further bring their work to the market.

Think of PoCs that demonstrate privacy-friendly applications with IRMA, or the memory-safe implementation of the Precision Time Protocol with support of the NLnet Foundation.

Tech we like

Rust. A fast and efficient system programming language with strong guarantees on memory safety and type safety. Checkout rust-lang.org or visit our open-source page and blog for more.

Featured project: Cryptify

Cryptify is a privacy-friendly file transfer application, designed with the goal of making encryption easily accessible to everyone.

Files are encrypted specifically for the email address of the receiver. Therefore, they can only be decrypted by proving ownership of the email address using IRMA.

To facilitate the sharing and (short-term) storage of files, we built the back-end providing a simple API. Read more on our work here.

Working with Tweede golf in practice

We are a close group of engineers and developers with a background in information security, mathematics and computer science. We think active collaboration is the most important condition for success.

Often a collaboration starts with a common interest or belief. We organize a workshop together or do a hack day to explore ideas we share.

We work on research projects on the one hand because we want to contribute to open-source software for a safer internet, and on the other because new technology fascinates us and keeps us sharp.

Whatever project you work on with us, large or small, you will always encounter a strong engineering mindset, the search for ever better software and tools, for elegant solutions and for secure and privacy-friendly software.

Featured project

TGuard


TGuard is a web application for sending encrypted email messages with IRMA. It can be used as a stand-alone service, but is mainly aimed as a fallback for IRMAseal encrypted messages. IRMAseal is part of the Encryption 4 All project led by the Radboud University.
TGuard is open-source and can be found here.
