In this lab, we will explore the process of decrypting a TLS connection using Wireshark. You'll start by downloading the provided PCAP file and the server's private key. The main focus is to analyze the encrypted TLS traffic and decrypt it using the private key. This is possible because the server does not use forward secrecy, allowing the decryption of past traffic if the private key is compromised.

To decrypt the traffic, you will select a TLS packet in Wireshark, access the protocol preferences, and input the necessary details such as IP address, port, protocol, and the server's private key. Once configured, Wireshark will decrypt the traffic, revealing the contents of the HTTP packets. Through this exercise, you will understand the risks associated with not using forward secrecy and the importance of choosing secure cipher suites to protect encrypted communications.
