An educational project that walks through a complete TLS 1.2 connection byte by byte, explaining every field of the handshake, published as an interactive website. It includes Go server and client code that reproduces the exact connection, plus PCAP and keylog captures.

Use cases

• learn how the TLS 1.2 handshake works byte by byte
• understand what each field in a ClientHello means
• study TLS record structure and cipher suite negotiation
• reproduce a real TLS 1.2 session with Go code
• teach students about TLS and SSL protocol internals
• analyze example PCAP and keylog files of a TLS session

When to choose

• you want a deep, byte-level explanation of TLS 1.2
• you are teaching or learning network security protocol internals
• you need a reproducible example TLS 1.2 client and server

When to avoid

• you need a production TLS library or implementation
• you want TLS 1.3 specifically (see the companion illustrated-tls13 project)
• you need a general-purpose packet analyzer
