Hi all!

I get certificate from MS CA.  
Then convert it:

```auto
    openssl pkcs12 -in test.pfx -out ca.crt -nodes -nokeys -cacerts
    openssl pkcs12 -in test.pfx -clcerts -nokeys -out server.crt
    openssl pkcs12 -in test.pfx -nocerts -nodes -out server.key

```

```
Then i configure Logstash input:

```

```auto
    input {
      beats {
        port => 5044
        ssl => true
        ssl_certificate_authorities => ["/usr/share/logstash/ssl/ca.crt"]
        ssl_certificate => "/usr/share/logstash/ssl/server.crt"
        ssl_key => "/usr/share/logstash/ssl/server.key"
        ssl_verify_mode => "none"
      }
    }

```

Theni started Logstash and get error:  
"File does not contain valid private key:/usr/share/logstash/ssl/server.key"

Help me please. What i do wrong? How fix it?

Thank you
