Angular with Relaunch

This course will teach you step-by-step how to design and architect large Angular applications. 

You’ll start with the basics: components, pipes, and directives. These are the building blocks of any Angular application, so you will get plenty of hands-on practice with this material. Next, you’ll ramp things up by stepping into modules, routing, and RXJS, where you’ll learn how to declaratively manage data and dive deep into observables.

In the latter half of the course, you’ll cover reactive and template forms (crucial for handling user data), as well as custom validators and setting up authentication with Firebase.

By the end of this course, you'll be able to design large, scalable applications, be able to develop rich interactive components, and you’ll really understand how Angular works under the hood.

Angular: Designing and Architecting Web Applications

The API we're using requires that we hash the password. But what exactly does that mean? Storing a password in plain text is considered bad practice. If a hacker can access the database, they'll be able to view every user's password.

In case a database is hacked, one way to secure passwords is by hashing them. Hashing is the process of converting a value into another. It makes a value challenging to recognize.

Hashing is a complex process that we won't dive into too much. There are hundreds of algorithms available for hashing values. Which algorithm you use is up to you. Let's look at an example of the SHA256 hash. It's a reasonably popular hash.

Check out this site: https://xorbin.com/tools/sha256-hash-calculator.

It's a tool for hashing text. Try to hash any value you'd like. The result will be some unreadable gibberish. However, that's the point. A hacker would have to figure out the original value AND the hash used. 

The Enzoic API expects a password that has been hashed. This way, we don't need to send the user's actual password over the request. The API supports md5, SHA1, and SHA256 hashes. We'll be using SHA256 because of its popularity and security.

# Installing Crypto JS

There's a library, called Crypto JS, that comes bundled with functions that will perform various hashes, including the SHA256 hash. It's called Crypto JS. We'll use it to hash the password that we'll send to the API.

In the command line, run the following command to install the library:

```bash
npm install crypto-js
```

# Hashing the password

Let's hash the password. We'll update the `enzoic.service.ts` file to the following:

In this lesson, we'll hash the password before sending it to the API.
