How to use confluent-kafka with the key store file

Question

When I use the Key store file, add property

ssl.keystore.location
ssl.keystore.password
ssl.key.password
ssl.truststore.location
ssl.truststore.password

in the config, it throws this error:

Can not find the property ssl.truststore.location"

How can I use librdkafka with key store file? It troubles me, does any one know how to use confluent-kafka with the key store file?

confluent-kafka: https://github.com/confluentinc/confluent-kafka-dotnet/

Follow the CONFIGURATION.md: https://github.com/edenhill/librdkafka/blob/master/CONFIGURATION.md

I can not find the property in the CONFIGURATION.md

Answer 1

ssl.keystore.* and ssl.truststore.* are Java client properties, which make use of Java's JAAS framework and Java-specific trust/keystores.

librdkafka (and its sibling clients) makes use of OpenSSL which uses the PEM and cert file formats.

See this guide how to set it up: https://github.com/edenhill/librdkafka/wiki/Using-SSL-with-librdkafka
