PQC in Practice: Why This, Not That?

on YouTube ↗55m

" summary

Discussion compares Chimera, composite and pure PQC strategies and gives concrete tradeoffs: Chimera certificates for backward interoperability, composite keys when both legacy and PQC must be trusted, and pure PQC for simplicity. Notes practical constraints: OpenSSL tooling lag, TLS short certs and 47-day lifetimes demand automation, and many deployments can use KEMs now but still face harvest-now-decrypt-later risk. Reissue, key management abstraction, and phased rollouts are the actionable paths described.
