Time flies and it’s already the fifth iteration of the current Feminist Linux Meetup cycle! Find the announcement with all the dates and topics here: https://feminist-linux.diebin.at/2025/12/20/save-the-dates-meetup-cycle-2026/

About the talk

On May 6, we will take a look at the basics of cryptography. We will visually explore some concepts while looking at concrete examples. Learn what cryptography even is, what its goals are and why it is so essential for modern computing and communication. No special math knowledge is required to join!

Get ready to understand the famous Diffie-Hellman key exchange! One of the core building blocks of the Signal protocol. Crypto-coins? Not part of this talk, sorry bros! Quantum?? We will not dive into that, but you will learn why people care. Signatures? Yes!

After the talk, motivated people can join up to tackle some riddles from the fun CrypoHack website using Python (or some other language of your choice). Sounds interesting? Then bring your programming device or watch along with somebody else: https://cryptohack.org/

(*) Invitation policy and social conduct

The meetup (and workshop) is open to all women*, non-binary*, inter*, and trans* people, who are interested to talk about Linux and related topics. In this case, non-binary does mean that you neither fully identify as „woman“ or „man“. It does not mean, that you only programme in fuzzy-logic and don’t use binary numbers. This would of course be fantasticly queer, but believe us, our computers also work with binary code most of the time.

With the * we mark certain words to point to the fact, that all these categories are socially constructed. That means, that they do not exist „in nature“, but that we humans interpret nature in this specific way. Therefore it is also legitimate, that people choose these categories for themselves in a way that best fits them. If that unsettles you or you want to know more about it, take a look at our article on invitation policy: https://feminist-linux.diebin.at/invitation-policy/

Beyond that, we want to create an atmosphere and environment that is encouraging everyone. To do so, we created a Code of Conduct, that describes what we all can do, that no one has to be uncomfortable: https://feminist-linux.diebin.at/code-of-conduct/

In order for everyone to feel really welcome and accepted though, we want to be actively aware and foster a social environment that we describe here: https://feminist-linux.diebin.at/social-framework/
