Chapter 8: Performing Common Cryptographic Operations in the Browser

In the previous chapter, we introduced the idea of performing cryptographic operations in the browser, and we looked at some core concepts, such as how to manage binary data in client-side JavaScript and how to create, import, and export keys with CryptoKey objects.

We'll cover the rest of the topics in this chapter by looking at how to perform the cryptographic operations we learned about in Part 2 of this book, this time within the web browser: hashing, symmetric encryption, asymmetric and hybrid encryption, and digital signatures.

Please note that we won't be explaining what each cryptographic operation does or when you should use which in this chapter. Because of that, I recommend that you familiarize yourself with the various operations first, reviewing Chapter 3, File and Password Hashing with Node.js to Chapter 6, Digital Signatures with Node.js and Trust, if needed.
