s3UpdateObjectEncryption
Updates the server-side encryption type of an existing encrypted object in a general purpose bucket. You can use the UpdateObjectEncryption operation to change encrypted objects from server-side encryption with Amazon S3 managed keys (SSE-S3) to server-side encryption with Key Management Service (KMS) keys (SSE-KMS), or to apply S3 Bucket Keys. You can also use the UpdateObjectEncryption operation to change the customer-managed KMS key used to encrypt your data so that you can comply with custom key-rotation standards.
