re-encrypt-data

Description

Re-encrypt ciphertext using DUKPT or Symmetric data encryption keys.

You can either generate an encryption key within Amazon Web Services Payment Cryptography by calling CreateKey or import your own encryption key by calling ImportKey . The KeyArn for use with this operation must be in a compatible key state with KeyModesOfUse set to Encrypt .

This operation also supports dynamic keys, allowing you to pass a dynamic encryption key as a TR-31 WrappedKeyBlock. This can be used when key material is frequently rotated, such as during every card transaction, and there is need to avoid importing short-lived keys into Amazon Web Services Payment Cryptography. To re-encrypt using dynamic keys, the keyARN is the Key Encryption Key (KEK) of the TR-31 wrapped encryption key material. The incoming wrapped key shall have a key purpose of D0 with a mode of use of B or D. For more information, see Using Dynamic Keys in the Amazon Web Services Payment Cryptography User Guide .

For symmetric and DUKPT encryption, Amazon Web Services Payment Cryptography supports TDES and AES algorithms. To encrypt using DUKPT, a DUKPT key must already exist within your account with KeyModesOfUse set to DeriveKey or a new DUKPT can be generated by calling CreateKey .

For information about valid keys for this operation, see Understanding key attributes and Key types for specific data operations in the Amazon Web Services Payment Cryptography User Guide .

Cross-account use : This operation can't be used across different Amazon Web Services accounts.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To re-encrypt data with a different key

The following re-encrypt-data example decrypts cipher text that was encrypted using an AES symmetric key and re-encrypts it using a Derived Unique Key Per Transaction (DUKPT) key.
