Q-Day: How Quantum Computing Will Break Today's Modern Cryptography (And What to Do About It)

May 13, 2026 | Online, Virtual

Have you ever wondered about the power of quantum computing, and the threat it poses to our state-of-the-art cryptography? In this webinar, I take you on deep-dive into the world of quantum, and showcase the danger quantum computers bring to a typical software development company by demonstrating which primitives a quantum computer breaks. As you'll see, these primitives include most of the modern symmetric and asymmetric ciphers, and more worrying, nearly the whole world uses them to present day. In fact, quantum computers empower the harvest-now-decrypt-later philosophy, and many attackers collect data now already for later decryption. However, the webinar will also give you hints on what you can do to protect your data now already, in an attempt to prevent the worst-case.
