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).

          .isNull();
    }
    assertWithMessage("Hex string and dec parm").that(Ints.tryParse("FFFF", 10)).isNull();
    assertWithMessage("Mixed hex case").that(Ints.tryParse("ffFF", 16)).isEqualTo(65535);
