generate-card-validation-data¶

Description¶

Generates card-related validation data using algorithms such as Card Verification Values (CVV/CVV2), Dynamic Card Verification Values (dCVV/dCVV2), or Card Security Codes (CSC). For more information, see Generate card data in the Amazon Web Services Payment Cryptography User Guide .

This operation generates a CVV or CSC value that is printed on a payment credit or debit card during card production. The CVV or CSC, PAN (Primary Account Number) and expiration date of the card are required to check its validity during transaction processing. To begin this operation, a CVK (Card Verification Key) encryption key is required. You can use CreateKey or ImportKey to establish a CVK within Amazon Web Services Payment Cryptography. The KeyModesOfUse should be set to Generate and Verify for a CVK encryption key.

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.

}

--validation-data-length (integer)

The length of the CVV or CSC to be generated. The default value is 3.

--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.

Global Options¶

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

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 generate a CVV

The following generate-card-validation-data example generates a CVV/CVV2.

aws payment-cryptography-data generate-card-validation-data \
    --key-identifier arn:aws:payment-cryptography:us-east-2:123456789012:key/kwapwa6qaifllw2h \
    --primary-account-number=171234567890123 \
    --generation-attributes CardVerificationValue2={CardExpiryDate=0123}

Output:

{
    "KeyArn": "arn:aws:payment-cryptography:us-east-2:123456789012:key/kwapwa6qaifllw2h",
    "KeyCheckValue": "CADDA1",
    "ValidationData": "801"
}

For more information, see Generate card data in the AWS Payment Cryptography User Guide.

Output¶

KeyArn -> (string)

The keyARN of the CVK encryption key that Amazon Web Services Payment Cryptography uses to generate CVV or CSC.

KeyCheckValue -> (string)

The key check value (KCV) of the encryption key. The KCV is used to check if all parties holding a given key have the same key or to detect that a key has changed.

Amazon Web Services Payment Cryptography computes the KCV according to the CMAC specification.

ValidationData -> (string)

The CVV or CSC value that Amazon Web Services Payment Cryptography generates for the card.
