# Code Examples for Client-Side Field Level Encryption in Confluent Cloud The following code examples and demos (for Java, Go, C#/.NET, JavaScript, 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](https://github.com/confluentinc/csfle-examples#readme) GitHub repository. ## Requirements * A Confluent Cloud cluster with Advanced Stream Governance enabled. For details, see [Dependency on Stream Governance](overview.md#csfle-governance-dependency). * For clients supporting CSFLE, see [Requirements](client-side.md#csfle-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](https://docs.confluent.io/clients-kafka-java/current/overview.html). * [Client-Side Field Level Encryption (CSFLE) with AWS KMS](https://github.com/confluentinc/csfle-examples/tree/master/aws#readme) * [Client-Side Field Level Encryption (CSFLE) with Azure Key Vault](https://github.com/confluentinc/csfle-examples/tree/master/azure#readme) * [Client-Side Field Level Encryption (CSFLE) with Google Cloud KMS](https://github.com/confluentinc/csfle-examples/tree/master/gcp#readme) * [Client-Side Field Level Encryption (CSFLE) with HashiCorp Vault](https://github.com/confluentinc/csfle-examples/tree/master/hashicorp#readme) ### Go These examples use the supported Golang client for Apache Kafka®.
