For this simple example, we are going to just be completely insecure and return the same `username` as the token.

/// tip

In the next chapter, you will see a real secure implementation, with password hashing and <abbr title="JSON Web Tokens">JWT</abbr> tokens.

But for now, let's focus on the specific details we need.

///

```
mc admin tier add s3 source S3TIER --bucket s3bucket --prefix testprefix/ --use-aws-role
```

        // toString() implementation may vary, just check it's not null and not empty
        assertFalse(stringRep.isEmpty());
    }

    @Test
    @DisplayName("Should generate correct associated data for AEAD")
    void testGetAssociatedData() {
        // Given
        transformHeader.setNonce(testNonce);
        transformHeader.setOriginalMessageSize(1024);
        transformHeader.setFlags(0x0001);

Ainda assim, a experiência final não foi a melhor. 😞

Para um exemplo "mais real", imagine um banco.

Até recentemente, a maioria dos bancos tinham muitos caixas 👨‍💼👨‍💼👨‍💼👨‍💼 e uma grande fila 🕙🕙🕙🕙🕙🕙🕙🕙.

Todos os caixas fazendo todo o trabalho, um cliente após o outro 👨‍💼⏯.
