# OAuth2 com Senha (e hashing), Bearer com tokens JWT

Agora que temos todo o fluxo de segurança, vamos tornar a aplicação realmente segura, usando tokens <abbr title="JSON Web Tokens">JWT</abbr> e hashing de senhas seguras.

Este código é algo que você pode realmente usar na sua aplicação, salvar os hashes das senhas no seu banco de dados, etc.

Vamos começar de onde paramos no capítulo anterior e incrementá-lo.

## Sobre o JWT

Entonces, con esa declaración de tipo, **FastAPI** te ofrece <abbr title="converting the string that comes from an HTTP request into Python data">"parsing"</abbr> automático de requests.

### <a href="https://apispec.readthedocs.io/en/stable/" class="external-link" target="_blank">APISpec</a> { #apispec }

Marshmallow and Webargs provide validation, parsing and serialization as plug-ins.

But documentation is still missing. Then APISpec was created.

It is a plug-in for many frameworks (and there's a plug-in for Starlette too).

        int written = trans2SetFileInfo.writeDataWireFormat(buffer, 0);

        // Should write FileInformation data + 6 bytes padding
        assertEquals(46, written); // 40 + 6

        // Verify encode was called
        verify(mockFileInfo).encode(buffer, 0);

        // Check that 6 bytes of padding are zeros
        for (int i = 40; i < 46; i++) {
            assertEquals(0, buffer[i]);
        }
    }

Nunca deberías guardar passwords en texto plano, así que, usaremos el sistema de hash de passwords (falso).

Si los passwords no coinciden, devolvemos el mismo error.

#### Hashing de passwords

"Hacer hash" significa: convertir algún contenido (un password en este caso) en una secuencia de bytes (solo un string) que parece un galimatías.
