Code Examples for Client-Side Field Level Encryption in Confluent Cloud

The following code examples and demos (for Java, Go, C#/.NET, Node.js, and Python) can be used to help you use client-side field level encryption in Confluent Cloud. These examples are available in the Client-Side Field Level Encryption (CSFLE) Examples GitHub repository.

Requirements

• A Confluent Cloud cluster with Advanced Stream Governance enabled. For details, see Dependency on Stream Governance.
• For clients supporting CSFLE, see Requirements.

Examples

Java

These following examples for producers and consumers use the supported Java client for Apache Kafka®. For details, see Apache Kafka Java Client.
