How do the world’s fastest databases and secure messaging apps actually communicate? In this video, we move beyond simple text-based streams and engineer a custom Binary Protocol in Rust.
We’ll dive deep into the world of systems networking, moving from raw TCP streams to a structured, authenticated communication system. I’ll show you how to solve the "TCP fragmentation" problem using a custom Framed Codec, and we’ll implement a Challenge-Response Handshake using RSA encryption to ensure only authorised clients can connect.
What we’re covering:
The "TCP Problem": Why TCP is a stream, not a packet carrier.
Custom Codec Design: Implementing Encoder and Decoder for binary framing.
Security & Auth: Building a 4-step RSA handshake with nonces and signatures.
Binary Serialisation: Why Bincode beats JSON for systems performance.
