There are more AWS SDK examples available in the AWS Doc SDK Examples GitHub repo.

Code examples for AWS KMS using AWS SDKs

The following code examples show you how to use AWS Key Management Service (AWS KMS) with an AWS software development kit (SDK).

Actions are code excerpts from larger programs and must be run in context. While actions show you how to call individual service functions, you can see actions in context in their related scenarios and cross-service examples.

Scenarios are code examples that show you how to accomplish a specific task by calling multiple functions within the same service.
