The doc ([https://www.elastic.co/guide/en/beats/filebeat/5.0/configuring-ssl-logstash.html](https://www.elastic.co/guide/en/beats/filebeat/5.0/configuring-ssl-logstash.html) )did not say which way to create these keys/certificates, I tried to create with openssl two-way SSL but does not work, error is:  
[2016-12-07T14:25:01,198][ERROR][logstash.inputs.beats] Looks like you either have an invalid key or your private key was not in PKCS8 format. {:exception=\>java.lang.IllegalArgumentException: File does not contain valid private key: /etc/logstash/logstash.key}

output.logstash:  
hosts: ["[logs.mycompany.com:5044](http://logs.mycompany.com:5044)"]  
ssl.certificate\_authorities: ["/etc/ca.crt"]  
ssl.certificate: "/etc/client.crt"  
ssl.key: "/etc/client.key"

input {  
beats {  
port =\> 5044  
ssl =\> true  
ssl\_certificate\_authorities =\> ["/etc/ca.crt"]  
ssl\_certificate =\> "/etc/server.crt"  
ssl\_key =\> "/etc/server.key"  
ssl\_verify\_mode =\> "force\_peer"  
}  
}

Please give me a full list of commands or a guide which works.

I've always been able to use an adaptation of what's in [https://github.com/elastic/logstash-forwarder/blob/master/README.md:](https://github.com/elastic/logstash-forwarder/blob/master/README.md:)

```
openssl req -x509 -batch -nodes -newkey rsa:2048 -keyout lumberjack.key -out lumberjack.crt -subj /CN=logstash.example.com
```
