PaymentCryptographyDataPlane **************************** Client ====== class PaymentCryptographyDataPlane.Client A low-level client representing Payment Cryptography Data Plane You use the Amazon Web Services Payment Cryptography Data Plane to manage how encryption keys are used for payment-related transaction processing and associated cryptographic operations. You can encrypt, decrypt, generate, verify, and translate payment-related cryptographic operations in Amazon Web Services Payment Cryptography. For more information, see Data operations in the *Amazon Web Services Payment Cryptography User Guide*. To manage your encryption keys, you use the Amazon Web Services Payment Cryptography Control Plane. You can create, import, export, share, manage, and delete keys. You can also manage Identity and Access Management (IAM) policies for keys. import boto3 client = boto3.client('payment-cryptography-data') These are the available methods: * can_paginate * close * decrypt_data * encrypt_data * generate_card_validation_data * generate_mac * generate_mac_emv_pin_change * generate_pin_data * get_paginator * get_waiter * re_encrypt_data * translate_pin_data * verify_auth_request_cryptogram * verify_card_validation_data * verify_mac * verify_pin_data PaymentCryptographyDataPlane / Client / re_encrypt_data re_encrypt_data *************** PaymentCryptographyDataPlane.Client.re_encrypt_data(**kwargs) 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. **Related operations:** * DecryptData * EncryptData * GetPublicCertificate * ImportKey See also: AWS API Documentation **Request Syntax** response = client.re_encrypt_data( IncomingKeyIdentifier='string', OutgoingKeyIdentifier='string', CipherText='string', IncomingEncryptionAttributes={ 'Symmetric': { 'Mode': 'ECB'|'CBC'|'CFB'|'CFB1'|'CFB8'|'CFB64'|'CFB128'|'OFB', 'InitializationVector': 'string', 'PaddingType': 'PKCS1'|'OAEP_SHA1'|'OAEP_SHA256'|'OAEP_SHA512' }, 'Dukpt': { 'KeySerialNumber': 'string', 'Mode': 'ECB'|'CBC', 'DukptKeyDerivationType': 'TDES_2KEY'|'TDES_3KEY'|'AES_128'|'AES_192'|'AES_256', 'DukptKeyVariant': 'BIDIRECTIONAL'|'REQUEST'|'RESPONSE', 'InitializationVector': 'string' } }, OutgoingEncryptionAttributes={ 'Symmetric': { 'Mode': 'ECB'|'CBC'|'CFB'|'CFB1'|'CFB8'|'CFB64'|'CFB128'|'OFB', 'InitializationVector': 'string', 'PaddingType': 'PKCS1'|'OAEP_SHA1'|'OAEP_SHA256'|'OAEP_SHA512' }, 'Dukpt': { 'KeySerialNumber': 'string', 'Mode': 'ECB'|'CBC', 'DukptKeyDerivationType': 'TDES_2KEY'|'TDES_3KEY'|'AES_128'|'AES_192'|'AES_256', 'DukptKeyVariant': 'BIDIRECTIONAL'|'REQUEST'|'RESPONSE', 'InitializationVector': 'string' } }, IncomingWrappedKey={ 'WrappedKeyMaterial': { 'Tr31KeyBlock': 'string', 'DiffieHellmanSymmetricKey': { 'CertificateAuthorityPublicKeyIdentifier': 'string', 'PublicKeyCertificate': 'string', 'KeyAlgorithm': 'TDES_2KEY'|'TDES_3KEY'|'AES_128'|'AES_192'|'AES_256'|'HMAC_SHA256'|'HMAC_SHA384'|'HMAC_SHA512'|'HMAC_SHA224', 'KeyDerivationFunction': 'NIST_SP800'|'ANSI_X963', 'KeyDerivationHashAlgorithm': 'SHA_256'|'SHA_384'|'SHA_512', 'SharedInformation': 'string' } }, 'KeyCheckValueAlgorithm': 'CMAC'|'ANSI_X9_24'|'HMAC'|'SHA_1' }, OutgoingWrappedKey={ 'WrappedKeyMaterial': { 'Tr31KeyBlock': 'string', 'DiffieHellmanSymmetricKey': { 'CertificateAuthorityPublicKeyIdentifier': 'string', 'PublicKeyCertificate': 'string', 'KeyAlgorithm': 'TDES_2KEY'|'TDES_3KEY'|'AES_128'|'AES_192'|'AES_256'|'HMAC_SHA256'|'HMAC_SHA384'|'HMAC_SHA512'|'HMAC_SHA224', 'KeyDerivationFunction': 'NIST_SP800'|'ANSI_X963', 'KeyDerivationHashAlgorithm': 'SHA_256'|'SHA_384'|'SHA_512', 'SharedInformation': 'string' } }, 'KeyCheckValueAlgorithm': 'CMAC'|'ANSI_X9_24'|'HMAC'|'SHA_1' } ) Parameters: * **IncomingKeyIdentifier** (*string*) -- **[REQUIRED]** The "keyARN" of the encryption key of incoming ciphertext data.

For more information, see Generate PIN data in the *Amazon Web Services Payment Cryptography User Guide*. PIN data is never transmitted in clear to or from Amazon Web Services Payment Cryptography. This operation generates PIN, PVV, or PIN Offset and then encrypts it using Pin Encryption Key (PEK) to create an "EncryptedPinBlock" for transmission from Amazon Web Services Payment Cryptography. This operation uses a separate Pin Verification Key (PVK) for VISA PVV generation. Using ECDH key exchange, you can receive cardholder selectable PINs into Amazon Web Services Payment Cryptography. The ECDH derived key protects the incoming PIN block. You can also use it for reveal PIN, wherein the generated PIN block is protected by the ECDH derived key before transmission from Amazon Web Services Payment Cryptography. For more information on establishing ECDH derived keys, see the Generating keys in the *Amazon Web Services Payment Cryptography User Guide*.

For more information, see Encrypt data in the *Amazon Web Services Payment Cryptography User Guide*. You can generate an encryption key within Amazon Web Services Payment Cryptography by calling CreateKey. You can import your own encryption key by calling ImportKey. For this operation, the key must have "KeyModesOfUse" set to "Encrypt". In asymmetric encryption, plaintext is encrypted using public component. You can import the public component of an asymmetric key pair created outside Amazon Web Services Payment Cryptography by calling ImportKey. 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 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. For EMV encryption, Amazon Web Services Payment Cryptography supports "TDES" algorithms.For asymmetric encryption, Amazon Web Services Payment Cryptography supports "RSA". When you use TDES or TDES DUKPT, the plaintext data length must be a multiple of 8 bytes. For AES or AES DUKPT, the plaintext data length must be a multiple of 16 bytes. For RSA, it sould be equal to the key size unless padding is enabled. To encrypt using DUKPT, you must already have a BDK (Base Derivation Key) key in your account with "KeyModesOfUse" set to "DeriveKey", or you can generate a new DUKPT key by calling CreateKey. To encrypt using EMV, you must already have an IMK (Issuer Master Key) key in your account with "KeyModesOfUse" set to "DeriveKey".

This operation generates an authenticated issuer script response by appending the incoming message data (APDU command) with the target encrypted PIN block in ISO2 format. The command structure and method to send the issuer script update to the card is not defined by this operation and is typically determined by the applicable payment card scheme. The primary inputs to this operation include the incoming new encrypted pinblock, PIN encryption key (PEK), issuer master key (IMK), primary account number (PAN), and the payment card derivation method. The operation uses two issuer master keys - secure messaging for confidentiality (IMK-SMC) and secure messaging for integrity (IMK- SMI). The SMC key is used to internally derive a key to secure the pin, while SMI key is used to internally derive a key to authenticate the script reponse as per the EMV 4.4 - Book 2 - Security and Key Management specification. This operation supports Amex, EMV2000, EMVCommon, Mastercard and Visa derivation methods, each requiring specific input parameters. Users must follow the specific derivation method and input parameters defined by the respective payment card scheme. Note: Use GenerateMac operation when sending a script update to an EMV card that does not involve PIN change. When assigning IAM permissions, it is important to understand that EncryptData using EMV keys and GenerateMac perform similar functions to this command. **Cross-account use**: This operation can't be used across different Amazon Web Services accounts. **Related operations:** * EncryptData * GenerateMac See also: AWS API Documentation **Request Syntax** response = client.generate_mac_emv_pin_change( NewPinPekIdentifier='string', NewEncryptedPinBlock='string', PinBlockFormat='ISO_FORMAT_0'|'ISO_FORMAT_1'|'ISO_FORMAT_3', SecureMessagingIntegrityKeyIdentifier='string', SecureMessagingConfidentialityKeyIdentifier='string', MessageData='string', DerivationMethodAttributes={ 'EmvCommon': { 'MajorKeyDerivationMode': 'EMV_OPTION_A'|'EMV_OPTION_B', 'PrimaryAccountNumber': 'string', 'PanSequenceNumber': 'string', 'ApplicationCryptogram': 'string', 'Mode': 'ECB'|'CBC', 'PinBlockPaddingType': 'NO_PADDING'|'ISO_IEC_7816_4', 'PinBlockLengthPosition': 'NONE'|'FRONT_OF_PIN_BLOCK' }, 'Amex': { 'MajorKeyDerivationMode': 'EMV_OPTION_A'|'EMV_OPTION_B', 'PrimaryAccountNumber': 'string', 'PanSequenceNumber': 'string', 'ApplicationTransactionCounter': 'string', 'AuthorizationRequestKeyIdentifier': 'string', 'CurrentPinAttributes': { 'CurrentPinPekIdentifier': 'string', 'CurrentEncryptedPinBlock': 'string' } }, 'Visa': { 'MajorKeyDerivationMode': 'EMV_OPTION_A'|'EMV_OPTION_B', 'PrimaryAccountNumber': 'string', 'PanSequenceNumber': 'string', 'ApplicationTransactionCounter': 'string', 'AuthorizationRequestKeyIdentifier': 'string', 'CurrentPinAttributes': { 'CurrentPinPekIdentifier': 'string', 'CurrentEncryptedPinBlock': 'string' } }, 'Emv2000': { 'MajorKeyDerivationMode': 'EMV_OPTION_A'|'EMV_OPTION_B', 'PrimaryAccountNumber': 'string', 'PanSequenceNumber': 'string', 'ApplicationTransactionCounter': 'string' }, 'Mastercard': { 'MajorKeyDerivationMode': 'EMV_OPTION_A'|'EMV_OPTION_B', 'PrimaryAccountNumber': 'string', 'PanSequenceNumber': 'string', 'ApplicationCryptogram': 'string' } } ) Parameters: * **NewPinPekIdentifier** (*string*) -- **[REQUIRED]** The "keyARN" of the PEK protecting the incoming new encrypted PIN block. * **NewEncryptedPinBlock** (*string*) -- **[REQUIRED]** The incoming new encrypted PIN block data for offline pin change on an EMV card. * **PinBlockFormat** (*string*) -- **[REQUIRED]** The PIN encoding format of the incoming new encrypted PIN block as specified in ISO 9564. * **SecureMessagingIntegrityKeyIdentifier** (*string*) -- **[REQUIRED]** The "keyARN" of the issuer master key (IMK-SMI) used to authenticate the issuer script response. * **SecureMessagingConfidentialityKeyIdentifier** (*string*) -- **[REQUIRED]** The "keyARN" of the issuer master key (IMK-SMC) used to protect the PIN block data in the issuer script response. * **MessageData** (*string*) -- **[REQUIRED]** The message data is the APDU command from the card reader or terminal.

For more information, see Translate PIN data in the *Amazon Web Services Payment Cryptography User Guide*. PIN block translation involves changing a PIN block from one encryption key to another and optionally change its format. PIN block translation occurs entirely within the HSM boundary and PIN data never enters or leaves Amazon Web Services Payment Cryptography in clear text. The encryption key transformation can be from PEK (Pin Encryption Key) to BDK (Base Derivation Key) for DUKPT or from BDK for DUKPT to PEK. Amazon Web Services Payment Cryptography also supports use of dynamic keys and ECDH (Elliptic Curve Diffie-Hellman) based key exchange for this operation. Dynamic keys allow you to pass a PEK as a TR-31 WrappedKeyBlock. They 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 translate PIN block using dynamic keys, the "keyARN" is the Key Encryption Key (KEK) of the TR-31 wrapped PEK. The incoming wrapped key shall have a key purpose of P0 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*. Using ECDH key exchange, you can receive cardholder selectable PINs into Amazon Web Services Payment Cryptography. The ECDH derived key protects the incoming PIN block, which is translated to a PEK encrypted PIN block for use within the service. You can also use ECDH for reveal PIN, wherein the service translates the PIN block from PEK to a ECDH derived encryption key. For more information on establishing ECDH derived keys, see the Generating keys in the *Amazon Web Services Payment Cryptography User Guide*. The allowed combinations of PIN block format translations are guided by PCI. It is important to note that not all encrypted PIN block formats (example, format 1) require PAN (Primary Account Number) as input. And as such, PIN block format that requires PAN (example, formats 0,3,4) cannot be translated to a format (format 1) that does not require a PAN for generation. 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*. Note: Amazon Web Services Payment Cryptography currently supports ISO PIN block 4 translation for PIN block built using legacy PAN length. That is, PAN is the right most 12 digits excluding the check digits. **Cross-account use**: This operation can't be used across different Amazon Web Services accounts. **Related operations:** * GeneratePinData * VerifyPinData See also: AWS API Documentation **Request Syntax** response = client.translate_pin_data( IncomingKeyIdentifier='string', OutgoingKeyIdentifier='string', IncomingTranslationAttributes={ 'IsoFormat0': { 'PrimaryAccountNumber': 'string' }, 'IsoFormat1': {} , 'IsoFormat3': { 'PrimaryAccountNumber': 'string' }, 'IsoFormat4': { 'PrimaryAccountNumber': 'string' } }, OutgoingTranslationAttributes={ 'IsoFormat0': { 'PrimaryAccountNumber': 'string' }, 'IsoFormat1': {} , 'IsoFormat3': { 'PrimaryAccountNumber': 'string' }, 'IsoFormat4': { 'PrimaryAccountNumber': 'string' } }, EncryptedPinBlock='string', IncomingDukptAttributes={ 'KeySerialNumber': 'string', 'DukptKeyDerivationType': 'TDES_2KEY'|'TDES_3KEY'|'AES_128'|'AES_192'|'AES_256', 'DukptKeyVariant': 'BIDIRECTIONAL'|'REQUEST'|'RESPONSE' }, OutgoingDukptAttributes={ 'KeySerialNumber': 'string', 'DukptKeyDerivationType': 'TDES_2KEY'|'TDES_3KEY'|'AES_128'|'AES_192'|'AES_256', 'DukptKeyVariant': 'BIDIRECTIONAL'|'REQUEST'|'RESPONSE' }, IncomingWrappedKey={ 'WrappedKeyMaterial': { 'Tr31KeyBlock': 'string', 'DiffieHellmanSymmetricKey': { 'CertificateAuthorityPublicKeyIdentifier': 'string', 'PublicKeyCertificate': 'string', 'KeyAlgorithm': 'TDES_2KEY'|'TDES_3KEY'|'AES_128'|'AES_192'|'AES_256'|'HMAC_SHA256'|'HMAC_SHA384'|'HMAC_SHA512'|'HMAC_SHA224', 'KeyDerivationFunction': 'NIST_SP800'|'ANSI_X963', 'KeyDerivationHashAlgorithm': 'SHA_256'|'SHA_384'|'SHA_512', 'SharedInformation': 'string' } }, 'KeyCheckValueAlgorithm': 'CMAC'|'ANSI_X9_24'|'HMAC'|'SHA_1' }, OutgoingWrappedKey={ 'WrappedKeyMaterial': { 'Tr31KeyBlock': 'string', 'DiffieHellmanSymmetricKey': { 'CertificateAuthorityPublicKeyIdentifier': 'string', 'PublicKeyCertificate': 'string', 'KeyAlgorithm': 'TDES_2KEY'|'TDES_3KEY'|'AES_128'|'AES_192'|'AES_256'|'HMAC_SHA256'|'HMAC_SHA384'|'HMAC_SHA512'|'HMAC_SHA224', 'KeyDerivationFunction': 'NIST_SP800'|'ANSI_X963', 'KeyDerivationHashAlgorithm': 'SHA_256'|'SHA_384'|'SHA_512', 'SharedInformation': 'string' } }, 'KeyCheckValueAlgorithm': 'CMAC'|'ANSI_X9_24'|'HMAC'|'SHA_1' } ) Parameters: * **IncomingKeyIdentifier** (*string*) -- **[REQUIRED]** The "keyARN" of the encryption key under which incoming PIN block data is encrypted.

Only one of the following top level keys can be set: "Tr31KeyBlock", "DiffieHellmanSymmetricKey". * **Tr31KeyBlock** *(string) --* The TR-31 wrapped key block. * **DiffieHellmanSymmetricKey** *(dict) --* The parameter information for deriving a ECDH shared key. * **CertificateAuthorityPublicKeyIdentifier** *(string) --* **[REQUIRED]** The "keyArn" of the certificate that signed the client's "PublicKeyCertificate". * **PublicKeyCertificate** *(string) --* **[REQUIRED]** The client's public key certificate in PEM format (base64 encoded) to use for ECDH key derivation. * **KeyAlgorithm** *(string) --* **[REQUIRED]** The key algorithm of the derived ECDH key. * **KeyDerivationFunction** *(string) --* **[REQUIRED]** The key derivation function to use for deriving a key using ECDH. * **KeyDerivationHashAlgorithm** *(string) --* **[REQUIRED]** The hash type to use for deriving a key using ECDH. * **SharedInformation** *(string) --* **[REQUIRED]** 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. Return type: dict Returns: **Response Syntax** { 'PinBlock': 'string', 'KeyArn': 'string', 'KeyCheckValue': 'string' } **Response Structure** * *(dict) --* * **PinBlock** *(string) --* The outgoing encrypted PIN block data after translation. * **KeyArn** *(string) --* The "keyARN" of the encryption key that Amazon Web Services Payment Cryptography uses to encrypt outgoing PIN block data after translation. * **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. **Exceptions** * "PaymentCryptographyDataPlane.Client.exceptions.ValidationExcept ion" * "PaymentCryptographyDataPlane.Client.exceptions.AccessDeniedExce ption" * "PaymentCryptographyDataPlane.Client.exceptions.ResourceNotFound Exception" * "PaymentCryptographyDataPlane.Client.exceptions.ThrottlingExcept ion" * "PaymentCryptographyDataPlane.Client.exceptions.InternalServerEx ception"
