Sorry for the beginner question, but I am having trouble regenerating the certificates that were made at deployment. I'm not familiar with how certificates work so I was hoping there might be a script that just regenerates them? I changed the ip of my elasticsearch server and the certificate was apparently bound to the initial ips. I prematurely deleted the certs inside the /config/certs directory and now I'm stuck. Anyone know how I can fix this without a full reinstall?

Hi,

Regenerating certificates for Elasticsearch can be done using the Elasticsearch certutil tool.

The basic steps are

Create CA

```auto
./bin/elasticsearch-certutil ca

```

Create Transport Certs

```auto
./bin/elasticsearch-certutil cert --ca elastic-stack-ca.p12

```

Create http certs

```auto
./bin/elasticsearch-certutil http

```

Move all the certs to the correct directories and make sure they are readable.

Detailed Steps are [Here](https://www.elastic.co/guide/en/elasticsearch/reference/current/manually-configure-security.html) as well

And i have some examples [here](https://github.com/bvader/howtos/tree/master/basic-security-elasticsearch-targz)...
