PQ hybrid (forward-secret against future quantum)

Negotiated key exchange	`X25519MLKEM768`
Classification	pq-hybrid
Cipher suite	`TLS_AES_128_GCM_SHA256`
Last observed	2026-05-06 11:37:56

Hybrid: X25519 ECDH + ML-KEM-768. The de-facto PQ standard, supported by Cloudflare, Google, Apple, Mozilla, AWS. ~99.99% of all PQ-enabled sites in 2026.

What this means

This endpoint uses post-quantum hybrid key exchange. The shared secret is the concatenation of a classical ECDH result and a ML-KEM result; a future quantum attacker would have to break both to recover the session. This is what Cloudflare, Google, Apple, AWS and Mozilla ship by default in 2026.
