Encryption in Logstash 5.6

Elastic Stack Logstash
1

Hello,

I have a logstash configuration file with JDBC and Kibana passwords in plaintext. Wondering how I can go about encrypting both of those passwords.
Logstash-Keystore seems like it is only available in 6.x versions and I was unable to make use of it in 5.6

Can someone help me figure out how to get rid of the plaintext passwords?

The keystore integration feature was added in Logstash 6.

IIRC, it was possible to use environment variables in Logstash 5.x, which can be used with service automation to obscure credentials, at least keeping them out of the pipeline configuration.
