I'm trying to generate a PEM certificate for elasticsearch using elasticsearch-certutil by introducing the following line

```auto
bin/elasticsearch-certutil ca --pem

```

Then, the program asks me to set a name for the resulting .zip . However, when finishing executing it, no .PEM has been issued from the program into the elasticsearch root directory.

I executed the program as root, using Elasticsearch 8.11 (the latest version up to date)

I appreciate any suggestion

This is expected, it will create a zip file with the certificate and key in _ **PEM format** _, it will not create a `.pem` file, it will create a `.crt` and a `.key` file.

So, if I want to use it in logstash, do I have only to change the extension .pem?

In the Elasticsearch output?

No, you need to use just the `.crt` file.

```auto
ssl_certificate_authorities => '/path/to/file/ca.crt'

```
