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.

## About JWT { #about-jwt }

JWT means "JSON Web Tokens".

It's a standard to codify a JSON object in a long dense string without spaces. It looks like this:

```

        int counter1 = buffer1.getInt();
        int counter2 = buffer2.getInt();

        assertEquals(counter1 + 1, counter2, "Counter should increment between nonces");
    }

    @Test
    @DisplayName("Should generate secure random nonces when requested")
    void testSecureNonceGeneration() {
        // Given

        CacheBuilder.newBuilder()
            .removalListener(removalListener)
            .expireAfterWrite(10, MILLISECONDS)
            .ticker(ticker)
            .build(loader);

    // Increment 100 times
    for (int i = 0; i < 100; ++i) {
      cache.getUnchecked(10).incrementAndGet();
      ticker.advance(1, MILLISECONDS);
    }

    assertThat(applyCount.get()).isEqualTo(evictionCount.get() + 1);
