picoquic — Spontaneous 1-RTT key update

Pass

Decoded it and completed the request.

The client did what the clause requires.

What was measured

Client

picoquic — picoquic + picotls, 8162550

Test

Spontaneous 1-RTT key update — q-key-update

Clause

RFC 9001 §6.2 (MUST)

Class

interoperability — Correctly decoded something valid but demanding.

Required behaviour

Update to the next key phase and carry on. Once a packet protected with the next phase is processed, §6.2 is a MUST — "The endpoint MUST update its send keys to the corresponding key phase in response" — so the response written after the update has to be read with the new keys and the request completed.

Reproduce it

The suite is the judge, so the reproduction is to point the same client at the same test and let the server report what it saw.

SESSION=$(curl -sX POST https://conformance.pqcrypta.com/session | jq -r .id)
# then drive picoquic at the test URL and read the verdict:
curl -s https://conformance.pqcrypta.com/report/$SESSION.json | jq '.results["q-key-update"]'
