If you check the new (fake) database `fake_users_db`, you will see how the hashed password looks like now: `"$2b$12$EixZaYVK1fsbw1ZfbX3OXePaWxn96p36WQoeG6Lruj3vjPGga31lW"`.

## Handle JWT tokens

Import the modules installed.

Create a random secret key that will be used to sign the JWT tokens.

To generate a secure random secret key use the command:

<div class="termy">

```console
$ openssl rand -hex 32

    /**
     * 
     * 
     * Property <tt>jcifs.resolveOrder</tt> (string, default <tt>LMHOSTS,DNS,WINS,BCAST</tt>)
     * 
     * @return order and selection of resolver modules, see {@link ResolverType}
     */
    List<ResolverType> getResolveOrder ();


    /**
     * 
     * Property <tt>jcifs.netbios.baddr</tt> (string, default <tt>255.255.255.255</tt>)
     * 

Pour déclarer ces types et les types internes, on utilise le module standard de Python `typing`.

Il existe spécialement pour supporter ces annotations de types.

#### `List`

Par exemple, définissons une variable comme `list` de `str`.

<span style="color: green;">INFO</span>:     Application startup complete.
```

</div>

/// note | "備考"
