## Como Parece

Vamos primeiro usar o código e ver como funciona, e depois voltaremos para entender o que está acontecendo.

## Crie um `main.py`
Copie o exemplo em um arquivo `main.py`:

{* ../../docs_src/security/tutorial001.py *}

## Execute-o

E copie a saída para a variável `SECRET_KEY` (não use a do exemplo).

Crie uma variável `ALGORITHM` com o algoritmo usado para assinar o token JWT e defina como `"HS256"`.

Crie uma variável para a expiração do token.
