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).

        assertEquals(1, stats.totalSuccesses);
        assertEquals(0, stats.totalFailures);
        assertEquals(1.0, stats.successRate);
    }

    @Test
    @DisplayName("Test circuit opens after failure threshold")
    void testCircuitOpensAfterThreshold() {
        // Fail 3 times to open the circuit
        for (int i = 0; i < 3; i++) {
            try {
                circuitBreaker.call(() -> {

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).

 *
 * <p>There are three Win32 function calls provided by the Windows SDK
 * that are important in the context of using jCIFS. They are:
 *
 * <ul>
 * <li> <code>CallNamedPipe</code> A message-type pipe call that opens,
 *      writes to, reads from, and closes the pipe in a single operation.
 * <li> <code>TransactNamedPipe</code> A message-type pipe call that
 *      writes to and reads from an existing pipe descriptor in one operation.

Import the modules installed.

Create a random secret key that will be used to sign the JWT tokens.

To generate a secure random secret key use the command:

<div class="termy">

```console
$ openssl rand -hex 32

09d25e094faa6ca2556c818166b7a9563b93f7099f6f0f4caa6cf63b88e8d3e7
```

</div>

And copy the output to the variable `SECRET_KEY` (don't use the one in the example).
