Inspect TLS encrypted traffic using mitmproxy and Wireshark

The article discusses the process of inspecting TLS encrypted traffic using mitmproxy and Wireshark. The author describes the need to inspect traffic flowing out of an application and the challenges faced due to limited documentation. The guide outlines the steps involved in setting up a container using systemd-nspawn, running mitmproxy for man-in-the-middle interception, and using Wireshark to decrypt the traffic. The author explains the use of wireguard-tools to establish a connection between the container and mitmproxy. The process involves creating a transparent proxy to intercept and decrypt the TLS traffic for live inspection. By configuring Wireshark to decrypt the traffic based on the SSLKEYLOGFILE, the author successfully inspects and validates code changes in real-time. Despite the complexity of the setup, the author hopes the information provided will be useful for others attempting to inspect TLS encrypted traffic. The article concludes with an invitation to engage with the Koyeb Community and explore the log exporter functionality on the platform.
