Learn to protect Java applications from quantum computing threats in this 48-minute conference talk from Spring I/O 2025. Explore the emerging security challenges posed by quantum computers and their potential to compromise current cryptographic algorithms, understanding why proactive measures are essential even before "Q-Day" arrives. Discover Hybrid Public Key Encryption (HPKE) as a quantum-resistant solution, examining how this new standard combines asymmetric Key Encapsulation Mechanisms (KEM), key derivation functions (KDF), and authenticated encryption with additional data (AEAD) to create robust security. Master the implementation of these cryptographic concepts within the JDK security framework and gain hands-on knowledge of integrating quantum-resistant messaging capabilities into Java applications. Utilize JDK security tools including keytool and Java Flight Recorder (JFR) to strengthen your applications against quantum-era threats, ensuring your systems remain secure in the face of advancing quantum computing capabilities.
