@TimV - I have a elasticsearch certificate in .pfx format which i want to use in the logstash output config to elasticsearch like below. However it seems logstash does not support pkcs#12 format.

So, do i need to request for .pem or .cer format?

```auto
output {
		elasticsearch {
			user => logstash_internal
			password => kibana
			cacert => "<path-to-cert-elk.pfx>"
			hosts => ["https://abcd.org:9200/"]
			index => "logstash-abcd-*"	
		}
	}
}

```

cacert support .cer or .pem  
you can request different format or convert .pfx to cer or .pem with openssl commands.

[here’s](https://www.sslshopper.com/article-most-common-openssl-commands.html) an example
