Post-quantum cryptography for .NET developers
summary
NIST finalizes three post‑quantum standards in August 2024 and the talk shows concrete .NET tooling: Kyber (ML KEM), Dilithium/Falcon for signatures, libs from OpenQSB/LEAQs and a .NET port via BouncyCastle. A Blazor WASM chat demo performs Kyber encapsulation, agrees a 32‑byte secret, and uses AES‑256 successfully; TLS hybrid proposals add ~2 KB handshake overhead. Experts predict large‑scale breaks in 15–30 years, so migration work and bindings (Java/Python/Go/C) are already shipping. Kyber (ML KEM) Blazor WASM demo
