What kind of encryption are you looking for? In transit? At rest? Specific fields in a document?

Encryption in transit has been available a long time but has only in recent versions been made available as part of the free basic license. Encryption at rest typically requires a tool like dm-crypt as there is no built in support. Encrypting parts of documents is as far as I know not supported at all.

Hi Christian!!

I am refering about encrypt some fields inside a Elaticsearch document. I don't see anything inside the official documentation.

Best Regards

I think you need to use Logstash cipher filter for this use case: [https://www.elastic.co/guide/en/logstash/current/plugins-filters-cipher.html](https://www.elastic.co/guide/en/logstash/current/plugins-filters-cipher.html)

It has nothing to do with Elasticsearch though, so you need to decrypt the fields by yourself.

Hi Javier,

if you refer to encryption of stored data you can try using a filesystem which supports encryption like ZFS.
