translatePinData

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.

At this time, Amazon Web Services Payment Cryptography does not support translations to PIN format 4.
