Project 1 / after M8

Measurement lab

Set up your own environment, measure classical and hybrid TLS yourself (X25519 vs X25519MLKEM768 ClientHello), count the segments, and explain the difference.

Deliverable: your own measurement table. Every number in the rest of the course is checked against this table. Without your own measurement, the rest of the course is just memorizing someone else's figures.

How to start: complete the M0 setup lessons (Docker or native) first. Run the real openssl s_client -curves X25519/X25519MLKEM768 -msg command from the M8 lesson tls13-hybrid-kex-measurement in your own environment, count the ClientHello and handshake bytes, and build your own table.

Rubric and workspace

Real `s_client -msg` output is pasted, not estimated

The delta is computed correctly and its MTU and segment impact is shown

Your measurement is compared with the course's 1,176 B delta (see M8). If it differs, the difference is tied to a specific, checkable cause (negotiated group, certificate size, extension overhead, TLS library version) or explicitly marked unresolved. A vague 'my environment is probably different' is not enough
