The encrypted form will be stored with the encryptedįile. Plaintext form is used to encrypt the data. The example function returns the data key in both its plaintext and encrypted forms. The example creates a data key forĮach file it encrypts, but it’s possible to use a single data key to encrypt multiple files. The data key isĬustomer managed and does not incur an AWS storage cost. To encrypt a file, the example create_data_key function creates a data key.
