# Client-Side Field Level Encryption Examples for Confluent Platform The following code examples and demos (for Java, Go, C#/.NET, JavaScript, and Python) can teach you how to use client-side field level encryption on Confluent Platform. You can find the example code in the [Client-Side Field Level Encryption (CSFLE) Examples](https://github.com/confluentinc/csfle-examples#readme) GitHub repository. ## Requirements * A Confluent Enterprise cluster version 8.0 or later. * For clients supporting CSFLE, see [Requirements](client-side.md#csfle-requirements). ## Examples ### Java These following producers and consumers examples use the Apache Kafka® Java client. [Apache Kafka Java Client](https://docs.confluent.io/clients-kafka-java/current/overview.html). * [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 Kafka Go client.
