Post-quantum TLS readiness

tportal.hr

Secure today, exposed to harvest-now-decrypt-later

Short answer

No. As of 2026-11-03, tportal.hr does not negotiate post-quantum key exchange; it uses x25519 over TLSv1.3 (Quantum Aether grade B), so recorded traffic is exposed to harvest-now-decrypt-later.
