## When using 'jks' format for certificates, each secret should contain a truststore and a keystore.

## ...
##
## When using 'pem' format for certificates, each secret should contain a public CA certificate, a public certificate and one private key.
## Create these secrets following the steps below:
## 1) Create a certificate key and signing request per Kafka broker, and sign the signing request with your CA
## 2) Rename your CA file to `kafka.ca.crt`.
## 3) Rename your certificates to `kafka-X.tls.crt` where X is the ID of each Kafka broker.
## 3) Rename your keys to `kafka-X.tls.key` where X is the ID of each Kafka broker.
