verify-pin-data

Description

Verifies pin-related data such as PIN and PIN Offset using algorithms including VISA PVV and IBM3624. For more information, see Verify PIN data in the Amazon Web Services Payment Cryptography User Guide .

This operation verifies PIN data for user payment card. A card holder PIN data is never transmitted in clear to or from Amazon Web Services Payment Cryptography. This operation uses PIN Verification Key (PVK) for PIN or PIN Offset generation and then encrypts it using PIN Encryption Key (PEK) to create an EncryptedPinBlock for transmission from Amazon Web Services Payment Cryptography.

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.

Ibm3624Pin -> (structure)

Parameters that are required to generate or verify Ibm3624 PIN.

PinValidationData -> (string)

The unique data for cardholder identification.

PinOffset -> (string)

The PIN offset value.

--primary-account-number (string)

The Primary Account Number (PAN), a unique identifier for a payment credit or debit card that associates the card with a specific account holder.

--pin-block-format (string)

The PIN encoding format for pin data generation as specified in ISO 9564. Amazon Web Services Payment Cryptography supports ISO_Format_0 and ISO_Format_3 .

The ISO_Format_0 PIN block format is equivalent to the ANSI X9.8, VISA-1, and ECI-1 PIN block formats. It is similar to a VISA-4 PIN block format. It supports a PIN from 4 to 12 digits in length.

The ISO_Format_3 PIN block format is the same as ISO_Format_0 except that the fill digits are random values from 10 to 15.

Possible values:

  • ISO_FORMAT_0
  • ISO_FORMAT_3
  • ISO_FORMAT_4

--dukpt-attributes (structure)

The attributes and values for the DUKPT encrypted PIN block data.

KeySerialNumber -> (string)

The unique identifier known as Key Serial Number (KSN) that comes from an encrypting device using DUKPT encryption method. The KSN is derived from the encrypting device unique identifier and an internal transaction counter.

DukptDerivationType -> (string)

The key type derived using DUKPT from a Base Derivation Key (BDK) and Key Serial Number (KSN). This must be less than or equal to the strength of the BDK. For example, you can't use AES_128 as a derivation type for a BDK of AES_128 or TDES_2KEY .

JSON Syntax:

{
  "KeySerialNumber": "string",

CertificateAuthorityPublicKeyIdentifier -> (string)

The keyArn of the certificate that signed the client's PublicKeyCertificate .

PublicKeyCertificate -> (string)

The client's public key certificate in PEM format (base64 encoded) to use for ECDH key derivation.

KeyDerivationFunction -> (string)

The key derivation function to use for deriving a key using ECDH.

KeyDerivationHashAlgorithm -> (string)

The hash type to use for deriving a key using ECDH.

SharedInformation -> (string)

A byte string containing information that binds the ECDH derived key to the two parties involved or to the context of the key.

It may include details like identities of the two parties deriving the key, context of the operation, session IDs, and optionally a nonce. It must not contain zero bytes, and re-using shared information for multiple ECDH key derivations is not recommended.

KeyCheckValueAlgorithm -> (string)

The algorithm that Amazon Web Services Payment Cryptography uses to calculate the key check value (KCV). It is used to validate the key integrity.

For TDES keys, the KCV is computed by encrypting 8 bytes, each with value of zero, with the key to be checked and retaining the 3 highest order bytes of the encrypted result. For AES keys, the KCV is computed using a CMAC algorithm where the input data is 16 bytes of zero and retaining the 3 highest order bytes of the encrypted result.

Shorthand Syntax:

WrappedKeyMaterial={Tr31KeyBlock=string,DiffieHellmanSymmetricKey={CertificateAuthorityPublicKeyIdentifier=string,PublicKeyCertificate=string,KeyAlgorithm=string,KeyDerivationFunction=string,KeyDerivationHashAlgorithm=string,SharedInformation=string}},KeyCheckValueAlgorithm=string

--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)

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 verify a PIN

The following verify-pin-data example validates a PIN for a PAN.

aws payment-cryptography-data verify-pin-data \

    --encryption-key-identifier arn:aws:payment-cryptography:us-east-2:111122223333:key/ivi5ksfsuplneuyt \
    --primary-account-number 171234567890123 \
    --pin-block-format ISO_FORMAT_0 \
    --verification-attributes VisaPin="{PinVerificationKeyIndex=1,VerificationValue=5507}" \
    --encrypted-pin-block AC17DC148BDA645E

    "VerificationKeyCheckValue": "7F2363",
    "EncryptionKeyArn": "arn:aws:payment-cryptography:us-east-2:111122223333:key/ivi5ksfsuplneuyt",
