ClientHello Server certificate Key exchange Encrypted channel verify session keys

Source (.reladraw)

node hello "ClientHello"
node scert "Server certificate"  below hello
node key "Key exchange"  below scert
node secure "Encrypted channel"  below key
edge hello -> scert
edge scert -> key "verify"
edge key -> secure "session keys"

How to use

  1. Open the Reladraw playground
  2. Paste the source above — the diagram re-solves live
  3. Export SVG from the playground, or render locally: npx reladraw ssl-tls-handshake.reladraw -o out.svg

When to use this template

ClientHello to certificate verification to key exchange to the encrypted channel.. Use it in security training — four nodes, and every audit question maps to one edge.

How to customize

  1. Add a step or node. Insert one line: node new_id 'New label' below anchor — placement is relative, so the solver re-flows the whole diagram instantly.
  2. Relabel an edge. Edit the text after the arrow: edge a -> b 'your label' — labels are the fastest way to carry rates, protocols or percentages.
  3. Change reading order. Swap a placement word: below to right of rotates a branch sideways without touching any other line.
