The generated certificates are valid till 05. Jun 2030.

The certificates are generated using catch-all SAN in the following procedure:

1. Generate the node's keystore:

    }

    public void test_user_city() {
        final User user = new User();
        assertNull(user.getCity());

        user.setCity("San Francisco");
        assertEquals("San Francisco", user.getCity());
    }

    @Test
    public void test_user_postOfficeBox() {
        final User user = new User();
        assertNull(user.getPostOfficeBox());

  }

    Function<String, Integer> japaneseToInteger = Functions.forMap(mJapaneseToInteger);

 *    purpose of the certificate like "Entrust Root Certification Authority - G2" or
 *    "www.squareup.com".
 *
 *  * **A set of hostnames.** These are in the certificate's subject alternative name (SAN)
 *    extension. A subject alternative name is either a literal hostname (`squareup.com`), a literal
 *    IP address (`74.122.190.80`), or a hostname pattern (`*.api.squareup.com`).

Download [`certgen`](https://github.com/minio/certgen/releases/latest) for your specific operating system and platform.

`certgen` is a simple *Go* tool to generate self-signed certificates, and provides SAN certificates with DNS and IP entries:

```sh
./certgen -host "10.10.0.3,10.10.0.4,10.10.0.5"
```
