## 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:

            InetAddresses.getCoercedIPv4Address(
                InetAddresses.forString("2001:0000:5136:f378:9000:73bf:3fff:fdd2")));

    // Test that an address hashes in to the 224.0.0.0/3 number-space.
    int coercedInt =
        InetAddresses.coerceToInteger(
            InetAddresses.getCoercedIPv4Address(InetAddresses.forString("2001:4860::1")));
    assertThat(coercedInt).isAtLeast(0xe0000000);

Então a configuração `admin_email` seria definida como `"******@****.***"`.

O `app_name` seria `"ChimichangApp"`.
