I'm trying to use my own **company.cer** file for elasticsearch's ssl configuration.

However, I've failed with some cases.

**The first case,** I use cer extension of the certificate file in below configuration

```auto
xpack.security.enabled: true
xpack.security.transport.ssl.enabled: true

xpack.security.http.ssl.certificate: company.cer 
xpack.security.http.ssl.certificate_authorities: company.cer 

xpack.security.transport.ssl.certificate: company.cer 
xpack.security.transport.ssl.certificate_authorities: company.cer 

```

**The second case** I have tried with pfx,

```auto
xpack.security.enabled: true
xpack.security.transport.ssl.enabled: true
xpack.security.transport.ssl.verification_mode: certificate
xpack.security.transport.ssl.keystore.path: company.pfx
xpack.security.transport.ssl.truststore.path: company.pfx
xpack.security.transport.ssl.keystore.password: password
xpack.security.transport.ssl.truststore.password: password
xpack.security.http.ssl.keystore.password: password
xpack.security.http.ssl.truststore.password: password

```

The password is the **password of pfx** file. But this configuration didn't worked.

**Then, I have tried generating** crt, key files via **OpenSSL** [From This Link](https://gist.github.com/mediaupstream/a2694859b1afa59f26be5e8f6fd4806a) with following configuration.

```auto
xpack.security.enabled: true
xpack.security.http.ssl.enabled: true
xpack.security.transport.ssl.enabled: true
xpack.security.http.ssl.key: company.key
xpack.security.http.ssl.certificate: company.crt
xpack.security.http.ssl.certificate_authorities: company.crt
xpack.security.transport.ssl.key: company.key
xpack.security.transport.ssl.certificate: company.crt
xpack.security.transport.ssl.certificate_authorities: company.crt

```

How can i configure Elasticsearch SSL from **cer** or **pfx** file ?

Thanks for answering
