Создайте случайный секретный ключ, который будет использоваться для подписи JWT-токенов.

Для генерации безопасного случайного секретного ключа используйте команду:

<div class="termy">

```console
$ openssl rand -hex 32

09d25e094faa6ca2556c818166b7a9563b93f7099f6f0f4caa6cf63b88e8d3e7
```

</div>

И скопируйте полученный результат в переменную `SECRET_KEY` (не используйте тот, что в примере).

pkg math, func RoundToEven(float64) float64
pkg math/big, const MaxBase = 62
pkg math/big, method (*Float) Sqrt(*Float) *Float
pkg math/big, method (*Int) CmpAbs(*Int) int
pkg math/rand, func Shuffle(int, func(int, int))
pkg math/rand, method (*Rand) Shuffle(int, func(int, int))
pkg net, method (*TCPListener) SyscallConn() (syscall.RawConn, error)
pkg net, method (*UnixListener) SyscallConn() (syscall.RawConn, error)

Now that we have all the security flow, let's make the application actually secure, using <abbr title="JSON Web Tokens">JWT</abbr> tokens and secure password hashing.

This code is something you can actually use in your application, save the password hashes in your database, etc.

We are going to start from where we left in the previous chapter and increment it.

	o.FilterPrefix = strings.TrimPrefix(o.Prefix, o.BaseDir)
	// Remove leading and trailing slashes.
	o.FilterPrefix = strings.Trim(o.FilterPrefix, slashSeparator)

	if strings.Contains(o.FilterPrefix, slashSeparator) {
		// Sanity check, should not happen.
		o.FilterPrefix = ""
	}
}

// filter will apply the options and return the number of objects requested by the limit.

}

// Go calls the given function in a new goroutine.
//
// The first call to return a non-nil error will be
// collected in errs slice and returned by Wait().
func (g *NotificationGroup) Go(ctx context.Context, f func() error, index int, addr xnet.Host) {
	r := rand.New(rand.NewSource(time.Now().UnixNano()))

	g.workers.Take()

	go func() {
		defer g.workers.Give()

		g.errs[index] = NotificationPeerErr{

Crie uma chave secreta aleatória que será usada para assinar os tokens JWT.

Para gerar uma chave secreta aleatória e segura, use o comando:

<div class="termy">

```console
$ openssl rand -hex 32

09d25e094faa6ca2556c818166b7a9563b93f7099f6f0f4caa6cf63b88e8d3e7
```

</div>

E copie a saída para a variável `SECRET_KEY` (não use a do exemplo).

	// so various tasks will be useful
	bootstrapTrace("initAutoHeal", func() {
		initAutoHeal(GlobalContext, z)
	})

	// initialize the object layer.
	defer setObjectLayer(z)

	r := rand.New(rand.NewSource(time.Now().UnixNano()))
	attempt := 1
	for {
		var err error
		bootstrapTrace(fmt.Sprintf("poolMeta.Init: loading pool metadata, attempt: %d", attempt), func() {

// along with this program.  If not, see <http://www.gnu.org/licenses/>.
