Este código es algo que puedes usar realmente en tu aplicación, guardar los hashes de las contraseñas en tu base de datos, etc.

Vamos a empezar desde donde lo dejamos en el capítulo anterior e incrementarlo.

## Acerca de JWT { #about-jwt }

JWT significa "JSON Web Tokens".

Es un estándar para codificar un objeto JSON en un string largo y denso sin espacios. Se ve así:

```

        assertNotNull(component1);
        assertNotNull(component2);

        // Should be same instance for singleton
        assertSame(component1, component2);
        // The first creation should increment the counter
        assertTrue("Instance count should be at least 1", SingletonTestComponent.getInstanceCount() >= 1);
    }

     * Test wrap method
     */
    public void test_wrap_basic() {

     * @return true if cache has changes
     */
    public boolean hasChanges() {
        return hasChanges;
    }

    /**
     * Get and increment inconsistency count
     *
     * @return the current inconsistency count
     */
    public int getInconsistencyCount() {
        return inconsistencyCount.getAndIncrement();
    }

}

	}

	defer sm.Unlock()
