`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"
```

A response similar to this one should be displayed:

```
2018/11/21 10:16:18 wrote public.crt
2018/11/21 10:16:18 wrote private.key
