# Segurança - Primeiros Passos

Vamos imaginar que você tem a sua API **backend** em algum domínio.

E você tem um **frontend** em outro domínio ou em um path diferente no mesmo domínio (ou em uma aplicação mobile).

E você quer uma maneira de o frontend autenticar o backend, usando um **username** e **senha**.

Nós podemos usar o **OAuth2** junto com o **FastAPI**.

- For instructions on using KES for encrypting the MinIO backend, follow the [KMS Quick Start](https://github.com/minio/minio/tree/master/docs/kms). The SSE-S3 configuration setup also supports MinIO KMS backend encryption.

## FAQ

> Why is this change needed?

Before, there were two separate mechanisms - S3 objects got encrypted using a KMS,

	xnet "github.com/minio/pkg/v3/net"
	"github.com/minio/pkg/v3/quick"
)

// Save config file to corresponding backend
func Save(configFile string, data interface{}) error {
	return quick.SaveConfig(data, configFile, globalEtcdClient)
}

// Load config from backend
func Load(configFile string, data interface{}) (quick.Config, error) {
	return quick.LoadConfig(configFile, globalEtcdClient, data)
}
