> [@Victor\_Guimaraes](#): > > From the link you posted above, the Exception are throw from the method `private void parse(DerValue val)` , my certificate are not a DER, but a PEM certificate as you can see on previous posts. Has any other configurations I must add to my `elasticsearch.yml` file to force then to parse the certificate as a PEM format? PEM formatted certificates contain DER encoded data so code eventually needs to parse the DER structure. See [this awesome reply from Tim](https://discuss.elastic.co/t/elasticsearch-certificate-requirements/188143/2?) regarding certificate encoding, formatting, etc. > [@Victor\_Guimaraes](#): > > I'm using the same certificate on many other places, as the Elasticsearch using SearchGuard and are working fine. I'm not arguing against that, I'm only saying what your logs are implying. - What Java version are you using in your other Elasticsearch installation? - Can you try and run this Elasticsearch instance with Java 11 ? - Can you try and run your other Elasticsearch installation with Java 12 ? Not sure what else to suggest without being able to test against your certificate/key. --- _[View the full topic](https://discuss.elastic.co/t/getting-signed-fields-invalid-when-configure-https-to-elastic-http-layer-with-x-pack/189162)._
