QUIC draft-22 with zero-length SCID (quic-go example) - keys are embedded
This capture contains two sessions, using AES and ChaCha20 ciphers
respectively. quic-go seems to send an empty SCID, this broke QUIC connection
tracking and decryption in Wireshark. I also found a bug in quic-go with
ChaCha20, the fixed version was used to generate this capture.
Reproducer commands are in
https://github.com/lucas-clemente/quic-go/issues/2123.
Basically:
Modify example/echo/echo.go and set KeyLogWriter in generateTLSConfig to
support SSLKEYLOGFILE.
# Ensure draft -22 is advertised on the wire to avoid -dudp.port==4242,quic
git show v0.12.0 | git apply
sudo tcpdump -i any -p -w quic-go-b083fd6f0e36-d22.pcap -f udp &
go build -mod=readonly ./example/echo
SSLKEYLOGFILE=quic-go-b083fd6f0e36.keys ./echo
GODEBUG=cpu.all=off SSLKEYLOGFILE=quic-go-b083fd6f0e36-d22.keys ./echo
