  title: Amazon KMS Provision Key and Encrypt
  summary: Create a KMS key, enable it, and immediately encrypt a payload with it.
  description: >-
    Stands up a brand-new KMS key ready for use in a single pass. The workflow
    creates a customer managed key, explicitly enables it to guarantee it is in
    an active state, and then encrypts a plaintext payload with the new key to
    confirm it is usable end to end. The generated KeyId flows from creation
    through enable and encrypt. Each step spells out its request inline, including
    the AWS JSON protocol X-Amz-Target header, so the flow can be read and
    executed without opening the underlying OpenAPI description.
