Hi OpenSSL users, Greetings from me! From this article (https://www.qacafe.com/resources/examples-of-tls-1-3/) and pcap file (https://www.cloudshark.org/captures/64d433b1585a), I know we can use s_server and s_client to simulate "TLS 1.3 Session Resumption". I tried following command:
echo | openssl s_client -tls1_3 -connect tls13.cloudflare.com:443 -reconnect But it seems not to work since there is no "pre_shared_key" extension, and every time s_client just initiated a new connection instead of resumption. Could anybody advise how to simulate "TLS 1.3 Session Resumption" through OpenSSL tools? Thanks very much in advance! Best Regards Nan Xiao
