About
This is a small collection of working notes about network systems — mostly the transport and security layers, and mostly written after spending an afternoon on something that should have taken ten minutes.
What this site is
- A place to keep notes I would otherwise lose.
- Written for my future self, published in case it is useful to anyone else.
- Static HTML. No tracking, no analytics, no third-party scripts.
What this site is not
- Not authoritative. Protocol behaviour changes; check the RFC and the implementation.
- Not a tutorial series. Entries are independent and uneven in depth.
- Not comprehensive. If a topic is missing, it is because I have not hit it yet.
Corrections
If something here is wrong, it is worth fixing. The notes are versioned; corrections get a date stamp rather than silent edits, so the error stays visible.
