Summary

In this first chapter, we have introduced the goal of this book – to provide practical foundations of cryptography for software developers. Then, we listed the concepts we'll be learning in the next chapters. We've also learned why developers should care about cryptography and discussed some best practices that people dealing with cryptography should follow as safeguards.

In the next chapter, we'll begin writing code, first by learning about how to deal with binary data in Node.js and how to encode that as text strings. We'll also look at how to generate random data with Node.js, something that we'll do frequently throughout this book.
