Today's Day Two Cloud explores post-quantum cryptography and how to make your cryptographic secrets safe from quantum computers. We're looking at a time horizon of at least five or ten years, so this isn't an immediate threat, but it doesn't hurt to start thinking about it now. We dive into how quantum computing and quantum encryption work, their impact on cryptographic secrets, what it means for technologies such as IPSec VPNs, and more. Melchior Aelmans is our guest.
