2023/06/08 - Payment Cryptography Data Plane - 11 new api methods
Changes Initial release of AWS Payment Cryptography DataPlane Plane service for performing cryptographic operations typically used during card payment processing.
Translates encrypted PIN block from and to ISO 9564 formats 0,1,3,4. For more information, see Translate PIN data in the Amazon Web Services Payment Cryptography User Guide .
PIN block translation involves changing the encrytion of PIN block from one encryption key to another encryption key and changing PIN block format from one to another without PIN block data leaving Amazon Web Services Payment Cryptography. 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 supports TDES and AES key derivation type for DUKPT tranlations. You can use this operation for P2PE (Point to Point Encryption) use cases where the encryption keys should change but the processing system either does not need to, or is not permitted to, decrypt the data.
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
At this time, Amazon Web Services Payment Cryptography does not support translations to PIN format 4.
Cross-account use : This operation can't be used across different Amazon Web Services accounts.

Generates pin-related data such as PIN, PIN Verification Value (PVV), PIN Block, and PIN Offset during new card issuance or reissuance. 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.

This operation validates the CVV or CSC codes that is printed on a payment credit or debit card during card payment transaction. The input values are typically provided as part of an inbound transaction to an issuer or supporting platform partner. Amazon Web Services Payment Cryptography uses CVV or CSC, PAN (Primary Account Number) and expiration date of the card to check its validity during transaction processing. In this operation, the CVK (Card Verification Key) encryption key for use with card data verification is same as the one in used for GenerateCardValidationData.

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.

Verifies Authorization Request Cryptogram (ARQC) for a EMV chip payment card authorization. For more information, see Verify auth request cryptogram in the Amazon Web Services Payment Cryptography User Guide .
ARQC generation is done outside of Amazon Web Services Payment Cryptography and is typically generated on a point of sale terminal for an EMV chip card to obtain payment authorization during transaction time. For ARQC verification, you must first import the ARQC generated outside of Amazon Web Services Payment Cryptography by calling ImportKey. This operation uses the imported ARQC and an major encryption key (DUKPT) created by calling CreateKey to either provide a boolean ARQC verification result or provide an APRC (Authorization Response Cryptogram) response using Method 1 or Method 2. The ARPC_METHOD_1 uses AuthResponseCode to generate ARPC and ARPC_METHOD_2 uses CardStatusUpdate to generate ARPC.

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 calculates the KCV by using standard algorithms, typically by encrypting 8 or 16 bytes or "00" or "01" and then truncating the result to the first 3 bytes, or 6 hex digits, of the resulting cryptogram.
Encrypts plaintext data to ciphertext using symmetric, asymmetric, or DUKPT data encryption key. 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 ).
for symmetric and DUKPT encryption, Amazon Web Services Payment Cryptography supports TDES and AES algorithms. For asymmetric encryption, Amazon Web Services Payment Cryptography supports RSA . To encrypt using DUKPT, you must already have a DUKPT key in your account with KeyModesOfUse set to DeriveKey , or you can generate a new DUKPT key by calling CreateKey.

Re-encrypt ciphertext using DUKPT, Symmetric and Asymmetric 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 .

Verifies a Message Authentication Code (MAC).
You can use this operation when keys won't be shared but mutual data is present on both ends for validation. In this case, known data values are used to generate a MAC on both ends for verification without sending or receiving data in ciphertext or plaintext. You can use this operation to verify a DUPKT, HMAC or EMV MAC by setting generation attributes and algorithm to the associated values. Use the same encryption key for MAC verification as you use for GenerateMac.

KeyArn (string) --
The keyARN of the encryption key that Amazon Web Services Payment Cryptography uses for MAC verification.
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 calculates the KCV by using standard algorithms, typically by encrypting 8 or 16 bytes or "00" or "01" and then truncating the result to the first 3 bytes, or 6 hex digits, of the resulting cryptogram.
Decrypts ciphertext data to plaintext using symmetric, asymmetric, or DUKPT data encryption key. For more information, see Decrypt data in the Amazon Web Services Payment Cryptography User Guide .
You can use an encryption key generated within Amazon Web Services Payment Cryptography, or you can import your own encryption key by calling ImportKey. For this operation, the key must have KeyModesOfUse set to Decrypt . In asymmetric decryption, Amazon Web Services Payment Cryptography decrypts the ciphertext using the private component of the asymmetric encryption key pair. For data encryption outside of Amazon Web Services Payment Cryptography, you can export the public component of the asymmetric key pair by calling GetPublicCertificate.
For symmetric and DUKPT decryption, Amazon Web Services Payment Cryptography supports TDES and AES algorithms. For asymmetric decryption, Amazon Web Services Payment Cryptography supports RSA . When you use DUKPT, for TDES algorithm, the ciphertext data length must be a multiple of 16 bytes. For AES algorithm, the ciphertext data length must be a multiple of 32 bytes.

The default is CBC.

Generates a Message Authentication Code (MAC) cryptogram within Amazon Web Services Payment Cryptography.
You can use this operation when keys won't be shared but mutual data is present on both ends for validation. In this case, known data values are used to generate a MAC on both ends for comparision without sending or receiving data in ciphertext or plaintext. You can use this operation to generate a DUPKT, HMAC or EMV MAC by setting generation attributes and algorithm to the associated values. The MAC generation encryption key must have valid values for KeyUsage such as TR31_M7_HMAC_KEY for HMAC generation, and they key must have KeyModesOfUse set to Generate and Verify .
