### 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"
```

## Operation IDs Personalizados y Mejores Nombres de Métodos

Puedes **modificar** la forma en que estos operation IDs son **generados** para hacerlos más simples y tener **nombres de métodos más simples** en los clientes.

En este caso tendrás que asegurarte de que cada operation ID sea **único** de alguna otra manera.
