Please check the config files for zookeepers, brokers, producers, and consumers on my git repo - https://github.com/vinclv/data-engineering-minds-kafka/tree/main/config/ssl

P.S: I mentioned as Part-3 inside the video instead of Part-4. Excuse me for that. If you experience any noise in the background, please change the video quality from 4K to HD.

𝐃𝐄𝐒𝐂𝐑𝐈𝐏𝐓𝐈𝐎𝐍:
This is the 4th part of my Apache Kafka series (in English). In this video, you will learn how to implement the below SSL security in a 3-node Kafka Cluster with 1 Zookeeper:
𝟏. 𝐙𝐨𝐨𝐤𝐞𝐞𝐩𝐞𝐫 𝐒𝐞𝐜𝐮𝐫𝐢𝐭𝐲 - Configuring Zookeeper, zookeeper-shell.sh and Kafka brokers to implement SSL encryption & authentication while launching the Zookeeper and connecting zookeeper-shell.sh & Kafka brokers to the zookeeper.
𝟐. 𝐊𝐚𝐟𝐤𝐚 𝐒𝐞𝐜𝐮𝐫𝐢𝐭𝐲 - Configuring Kafka brokers, console producers and consumers to implement SSL encryption & authentication while launching the brokers and connecting producers & consumers to the brokers.

Please check the below videos in my Apache Kafka series as a prerequisite to this video:
1. Setup a 3-node Kafka Cluster locally - https://www.youtube.com/watch?v=gwrslUOSez8
2. SSL/TLS concepts in Apache Kafka with example - https://www.youtube.com/watch?v=N1pqDgaeNWU

Useful Links:
1. Download JCE files for Java 8 - https://www.oracle.com/java/technologies/javase-jce8-downloads.html

Example steps to implement CA, truststore and keystore for zookeeper SSL security :
𝟏. 𝐆𝐞𝐧𝐞𝐫𝐚𝐭𝐞 𝐂𝐀 == openssl req -new -x509 -keyout ca-key -out ca-cert -days 3650
𝟐. 𝐂𝐫𝐞𝐚𝐭𝐞 𝐓𝐫𝐮𝐬𝐭𝐬𝐭𝐨𝐫𝐞 == keytool -keystore kafka.zookeeper.truststore.jks -alias ca-cert -import -file ca-cert
𝟑. 𝐂𝐫𝐞𝐚𝐭𝐞 𝐊𝐞𝐲𝐬𝐭𝐨𝐫𝐞 == keytool -keystore kafka.zookeeper.keystore.jks -alias zookeeper -validity 3650 -genkey -keyalg RSA -ext SAN=dns:localhost
𝟒. 𝐂𝐫𝐞𝐚𝐭𝐞 𝐜𝐞𝐫𝐭𝐢𝐟𝐢𝐜𝐚𝐭𝐞 𝐬𝐢𝐠𝐧𝐢𝐧𝐠 𝐫𝐞𝐪𝐮𝐞𝐬𝐭 (𝐂𝐒𝐑) == keytool -keystore kafka.zookeeper.keystore.jks -alias zookeeper -certreq -file ca-request-zookeeper
𝟓. 𝐒𝐢𝐠𝐧 𝐭𝐡𝐞 𝐂𝐒𝐑 == openssl x509 -req -CA ca-cert -CAkey ca-key -in ca-request-zookeeper -out ca-signed-zookeeper -days 3650 -CAcreateserial
𝟔. 𝐈𝐦𝐩𝐨𝐫𝐭 𝐭𝐡𝐞 𝐂𝐀 𝐢𝐧𝐭𝐨 𝐊𝐞𝐲𝐬𝐭𝐨𝐫𝐞 == keytool -keystore kafka.zookeeper.keystore.jks -alias ca-cert -import -file ca-cert
𝟕. 𝐈𝐦𝐩𝐨𝐫𝐭 𝐭𝐡𝐞 𝐬𝐢𝐠𝐧𝐞𝐝 𝐜𝐞𝐫𝐭𝐢𝐟𝐢𝐜𝐚𝐭𝐞 𝐢𝐧𝐭𝐨 𝐊𝐞𝐲𝐬𝐭𝐨𝐫𝐞 == keytool -keystore kafka.zookeeper.keystore.jks -alias zookeeper -import -file ca-signed-zookeeper
Thanks for watching !!
