Logstash to logstash, how can we enable SSL communication with http out -\> http in plugins ?

for the moment , unsecured, the two instances as below work fine

```auto
 output {
    http {
        url => "the url"
        http_method => post
    }
}

input {
    http {
    port => 5044
  }
}

```

The configuration for SSL is very confusing and the documentation is only regards to beats-logstash or logstash-elastic.

So for http output there are the below options

```auto
cacert =>
client_cert => 
client_key =>

```

for http in there is the deprecated

```auto
keystore => 
keystore_password => 

```

and the rest

```auto
ssl_certificate =>
ssl_certificate_authorities =>
ssl_key => 
ssl_key_passphrase => 

```

I am totaly confused on how to proceed. Should I use ca.crt ? jks ? the ssl key is in pkcs8 format ? pem ? p12 ? Also the url should be https now right ?

The closest post i found is [Http output plugin json\_batch format to Http input plugin - #10 by Aceman87](https://discuss.elastic.co/t/http-output-plugin-json-batch-format-to-http-input-plugin/127462/10)  
but still couldnt get it to work.

Any help is appreciated  
Thanks!
