output key in a file(attachment: sslkey.log), and set this sslkey.log into "(Pre)-Master-Secret log filename". The quic payload can't be decrypted.

As I can't upload file, paste sslkey.log content here:

CLIENT_HANDSHAKE_TRAFFIC_SECRET e0e059352a2fae884377a78c6c8cffd86b97ea726bec0929c369e843e69358db db897d397b6258be06736bbab7332634e544383f64027aff6d5880b84ab2b453

I also set the tls debug out, from the log:

trying to use TLS keylog in D:\mywork\bug\delta\sslkey.log
tls13_get_quic_secret Cannot find QUIC SERVER_HANDSHAKE_TRAFFIC_SECRET of size 32..32, found bad size 0!

It seems wireshark can't read out the key from sslkey.log.

And the TLS client generating the sslkey.log file?

grahamb ( 2020-07-10 09:20:54 +0000 )edit

The sslkey.log and corresponding wireshark log is collecting from client side. I just take a look packet-tls.c. Base on the deubg log: tls13_get_quic_secret Cannot find QUIC SERVER_HANDSHAKE_TRAFFIC_SECRET

Wireshark seems this is from server side? why??

tls13_get_quic_secret(...){ ...

 case TLS_SECRET_HANDSHAKE:
     if (is_from_server) {
         label = "SERVER_HANDSHAKE_TRAFFIC_SECRET";

... }
