Network Programming with Rust

Overview of this book

Rust is low-level enough to provide fine-grained control over memory while providing safety through compile-time validation. This makes it uniquely suitable for writing low-level networking applications. This book is divided into three main parts that will take you on an exciting journey of building a fully functional web server. The book starts with a solid introduction to Rust and essential networking concepts. This will lay a foundation for, and set the tone of, the entire book. In the second part, we will take an in-depth look at using Rust for networking software. From client-server networking using sockets to IPv4/v6, DNS, TCP, UDP, you will also learn about serializing and deserializing data using serde. The book shows how to communicate with REST servers over HTTP. The final part of the book discusses asynchronous network programming using the Tokio stack. Given the importance of security for modern systems, you will see how Rust supports common primitives such as TLS and public-key cryptography. After reading this book, you will be more than confident enough to use Rust to build effective networking software

Summary

In this chapter, we took a quick look at securing communication over public networks. We started with an overview of certificates and how they are used for identifying servers on the web. We looked at using letsencrypt and openssl in Rust. We then moved on to securing Tokio applications using the same techniques. Finally, we took a quick look at doing key exchanges using the DH method.

The following section is the appendix; there, we will look at some extra crates and techniques that are becoming popular in the community.
