Hello,

I'm trying to configure Kafka output module for Logstash. I have my PKCS12 keystore and truststore prepared with proper key and certs added, but I wonder - if there are more keys in the keystore, how does Logstash choose only one? I see no way to configure this. Or is there a default alias this key should have?

Thanks.
