See all network traffic in a Go program, even when encrypted and compressed

Read Original

This article provides a detailed, step-by-step tutorial on leveraging DTrace to observe all network traffic generated by a Go program, including data that is encrypted (e.g., TLS/HTTPS) or compressed. It covers tracing system calls, filtering for network data, and methods to view the data in clear text, using the implementation of an OAuth2 login flow as a practical example.
