Hi, I’m Franziskus, a security & cryptography engineer and researcher based in Berlin currently leading the security engineering efforts at Wire.

Previously, I was working on Mozilla’s cryptography library NSS. I’m interested in everything around applied cryptography, in particular authentication and key exchange protocols, formally verifiable specifications and implementations of cryptographic primitives, and privacy preserving data collection and computation. I’m also the initiator and co-organiser of the Berlin Crypto Meetup.

If you want to get in touch, send me a message to mail@ this domain or a DM on Twitter.
