Post-quantum TLS readiness
justpaste.it
Secure today, exposed to harvest-now-decrypt-later
Short answer
No. As of 2026-11-03, justpaste.it does not negotiate post-quantum key exchange; it uses secp384r1 over TLSv1.3 (Quantum Aether grade B), so recorded traffic is exposed to harvest-now-decrypt-later.
