These credentials can now be used to perform MinIO API operations, these credentials automatically expire in 1hr. To understand more about credential expiry duration and client grants STS API read further [here](https://github.com/minio/minio/blob/master/docs/sts/client-grants.md).

### 4. Test with MinIO STS API

Once etcd is configured, **any STS configuration** will work including Client Grants, Web Identity or AD/LDAP.

## Dependencias para un grupo de *path operations* { #dependencies-for-a-group-of-path-operations }

Más adelante, cuando leas sobre cómo estructurar aplicaciones más grandes ([Aplicaciones Más Grandes - Múltiples Archivos](../../tutorial/bigger-applications.md){.internal-link target=_blank}), posiblemente con múltiples archivos, aprenderás cómo declarar un único parámetro `dependencies` para un grupo de *path operations*.

func getRandomRange(minN, maxN int, seed int64) int {
	// special value -1 means no explicit seeding.
	if seed == -1 {

	}
	return rand.New(rand.NewSource(seed)).Intn(maxN-minN) + minN
}
