Here is how SKIP actually works in a lab, with a Catalyst 8000v as the encryptor and PQCagent as the key provider. https://www.employees.org/~jdal/tech/pqc/skip-vs-etsi14/ Sat, 30 May 2026 00:00:00 +0000 https://www.employees.org/~jdal/tech/pqc/skip-vs-etsi14/ QKD gives you quantum-safe keys. SKIP (and its rival ETSI-14) are the protocols that get those keys into your VPN. Here is how they work and why we ended up with two of them. https://www.employees.org/~jdal/tech/pqc/ppk-post-quantum-preshared-keys/ Wed, 27 May 2026 00:00:00 +0000 https://www.employees.org/~jdal/tech/pqc/ppk-post-quantum-preshared-keys/ How IKEv2 accidentally broke quantum resistance and why we’re bringing back pre-shared keys to protect VPNs from future quantum computers.
