## Como Parece { #how-it-looks }

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

## Crie um `main.py` { #create-main-py }

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

{* ../../docs_src/security/tutorial001_an_py39.py *}

## Execute-o { #run-it }

/// info | Informação

        // Signing key may or may not be generated depending on flags negotiation
        // The context negotiates flags with server, so we can't guarantee signing key
