An approach to protocol reverse-engineering

Read Original

The article details a practical approach to protocol reverse-engineering for creating a label printer driver in Go. The author captures all data packets sent by an existing Python reference implementation by wrapping the socket's send() method, storing the datagrams in JSON format. This captured data is then used to build a test suite in Go that asserts the new implementation sends identical bytes, ensuring functional parity before further development.
