Observe the encrypted application data.Expand Secure Sockets Layer and TLS to view SSL/TLS details.Select the various TLS packets labeled Application Data.To analyze HTTPS encrypted data exchange: This is the server confirming the encrypted session.Īctivity 9 - Analyze HTTPS Encrypted Data Exchange Observe the encrypted handshake message.Expand Secure Sockets Layer, TLS, Handshake Protocol, TLS Session Ticket, and Encrypted Handshake Message to view SSL/TLS details.Select the TLS packet labeled New Session Ticket.To analyze SSL/TLS New Session Ticket traffic: This encrypted handshake contains the session key that will be used to encrypt session traffic.Īctivity 8 - Analyze SSL/TLS New Session Ticket Traffic Expand Secure Sockets Layer, TLS, Handshake Protocol, and Encrypted Handshake Message to view SSL/TLS details.Select the fourth TLS packet, labeled Client Key Exchange, Change Cipher Spec, Encrypted Handshake Message.To analyze SSL/TLS Client Key Exchange traffic: This is the client TCP acknowledgement of

This is the server TCP acknowledgement of receiving the Client Hello request.Īctivity 5 - Analyze SSL/TLS Server Hello Traffic

Select the next packet, labeled TCP ACK.

Observe the Cipher Suites and Extensions supported.

Expand Secure Sockets Layer, TLS, and Handshake Protocol to view SSL/TLS details.

Also notice that the Ethernet II, Internet Protocol Version 4, and Transmission Control Protocol values are consistent with the TCP connection analyzed in Activity 3. Notice that it is an Ethernet II / Internet Protocol Version 4 / Transmission Control Protocol / Secure Sockets Layer frame.

Observe the packet details in the middle Wireshark packet details pane.

Select the first TLS packet, labeled Client Hello.

Observe the traffic captured in the top Wireshark packet list pane.

Note that all of the packets for this connection will have matching MAC addresses, IP addresses, and port numbers.Īctivity 4 - Analyze SSL/TLS Client Hello Traffic Notice that it is a dynamic port selected for this HTTPS connection.

Expand Transmission Control Protocol to view TCP details.

Notice that the destination address is the IP address of the HTTPS server. Notice that the source address is your IP address.

Expand Internet Protocol Version 4 to view IP details.

You can use ipconfig /all and arp -a to confirm. The destination should be your default gateway's MAC address and the source should be your MAC address.

Observe the Destination and Source fields.

Expand Ethernet II to view Ethernet details.

Notice that it is an Ethernet II / Internet Protocol Version 4 / Transmission Control Protocol frame.

The first three packets (TCP SYN, TCP SYN/ACK, TCP ACK) are the TCP three way handshake.

To view all related traffic for this connection, change the filter to ip.addr =, where is the destination address of the HTTP packet.Īctivity 3 - Analyze TCP Connection Traffic.Select the first TLS packet labeled Client Hello.To view only HTTPS traffic, type ssl (lower case) in the Filter box and press Enter.
