Este código é algo que você pode realmente usar na sua aplicação, salvar os hashes das senhas no seu banco de dados, etc.

Vamos começar de onde paramos no capítulo anterior e incrementá-lo.

## Sobre o JWT { #about-jwt }

JWT significa "JSON Web Tokens".

É um padrão para codificar um objeto JSON em uma string longa e densa sem espaços. Ele se parece com isso:

  }

  /** Snapshot iterator that works off copy of underlying q array. */
  private class Itr implements Iterator<E> {
    final Object[] array; // Array of all elements
    int cursor; // index of next element to return;
    int lastRet; // index of last element, or -1 if no such

    Itr(Object[] array) {
      lastRet = -1;
      this.array = array;
    }

    @CanIgnoreReturnValue // pushed down from class to method

  }

  /**
   * Returns the index in {@code iterable} of the first element that satisfies the provided {@code
   * predicate}, or {@code -1} if the Iterable has no such elements.
   *
   * <p>More formally, returns the lowest index {@code i} such that {@code
   * predicate.apply(Iterables.get(iterable, i))} returns {@code true}, or {@code -1} if there is no
   * such index.
   *

When working on some source code it is important to be aware of the runtimes in which it will run, so that you don't break these constraints.
There is some assistance in the IDE for this plus a lot of validation that is applied at build time and on CI, but it is useful to keep these constraints in mind as well.

See [Gradle runtimes](runtimes.md) for a list of these runtimes and more details.
