Cryptography: The Weird Bits – Eli Holderness & Rendle

Join Rendle and Eli at NDC Copenhagen 2025 for a whirlwind tour of cryptography’s oddest corners. Between live coding, jaw-dropping history and maths that’ll make your brain do somersaults, you’ll discover stuff you’ve seen before… and a whole lot you haven’t.

Expect cool-as-hell stories, unhinged tangents and practical tips that go beyond your basic internet-banking encryption. If you’re even a little bit weird about maths (or just love a good DevFest hour), this is your jam.
