I am using a library in lua (openresty) to interact with kafka: github. Readme.md describes SSL support for kafka. To connect, I use the following code
local kafka = producer: new (broker_list, {["producer.type"] = "async", ["ssl"] = true}).
How do I initialize truststore_location, keystore_location, keystore_password, key_password? I didn't find an example in the repository and stackoverflow
