WWDC25: Get ahead with quantum-secure cryptography | Apple

Learn how to protect your app’s sensitive user data from the emerging threat of quantum computing, and safeguard user privacy. We’ll explore different quantum attacks, their impact on existing cryptographic protocols, and how to defend against them using quantum-secure cryptography. You’ll learn how to use quantum-secure TLS to secure network data, and use CryptoKit’s quantum-secure APIs for securing application data.
