# TLS/SSL 抓包 wireshark 分析
# Demo

1. Start  Server
$ openss s_server -accept 8443 -cert pubcert.pem -key privkey.pem
2. Start tcpdump
$ tcpdump -I lo -w tls_demo.pcap 
3. Start Client, Send some data to Server
$ openssl s_client - connect localhost:8443
4. Server receive & send some data

5. Stop tcpdump

6. Wireshark analyse tls_demo.pcap with tls_demo.keys, can see decrypted message.
