Summary

In this chapter, we started looking into performing cryptographic operations in the web browser using frontend JavaScript code. Doing this allows us to build more kinds of applications, such as those using end-to-end encryption, but it also comes with other challenges and security risks, including some that are unique to code that runs in a web browser.

We then started looking at some "core" concepts for using cryptography in the browser, including dealing with binary data, using base64 and hex encoding, and working with keys: generating, importing, and exporting them.

In the next chapter, we'll continue exploring how to perform cryptography in the browser by completing our overview of the Web Crypto APIs, plus more.
