Upload pcap File

You can upload a PCAP file, and we will provide an anotated list of TLS fingerprints that we can extract. We currently only parse TCP/443 packets, and only parse Client Hello messages.

To capture only client hello messages with tcpdump, use:

'(tcp[tcp[12]/4]=22) and (tcp[tcp[12]/4+1]=3) and (tcp[tcp[12]/4+5]=1) and (tcp[tcp[12]/4+9]=3)'
