### 3.1 Use `certgen` to Generate a Certificate

Download [`certgen`](https://github.com/minio/certgen/releases/latest) for your specific operating system and platform.

`certgen` is a simple *Go* tool to generate self-signed certificates, and provides SAN certificates with DNS and IP entries:

```sh
./certgen -host "10.10.0.3,10.10.0.4,10.10.0.5"
```

## Mais detalhes sobre `SecurityScopes` { #more-details-about-securityscopes }

Você pode utilizar `SecurityScopes` em qualquer lugar, e em diversos lugares. Ele não precisa estar na dependência "raiz".

Ele sempre terá os escopos de segurança declarados nas dependências atuais de `Security` e todos os dependentes para **aquela** *operação de rota* **específica** e **aquela** árvore de dependência **específica**.

### Sempre levante (`raise`) em Dependências com `yield` e `except` { #always-raise-in-dependencies-with-yield-and-except }
