Postquantum cryptography in TLS

The National Cyber and Information Security Agency of the Czech Republic has confirmed that “harvest now, decrypt later” attacks are no longer a theoretical threat—they are already a reality. In this talk, I will demonstrate how to protect sensitive data by integrating post-quantum key exchange into the TLS protocol. This hybrid approach, combining classical and quantum-resistant algorithms, is already supported by major web browsers and several TLS libraries. Attendees will learn how to adopt these mechanisms today to provide practical, forward-compatible security in the face of emerging quantum threats.
