// Translates encrypted PIN block from and to ISO 9564 formats 0,1,3,4. For more
// information, see Translate PIN data (https://docs.aws.amazon.com/payment-cryptography/latest/userguide/translate-pin-data.html)
// 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 (https://docs.aws.amazon.com/payment-cryptography/latest/userguide/keys-validattributes.html)
// and Key types for specific data operations (https://docs.aws.amazon.com/payment-cryptography/latest/userguide/crypto-ops-validkeys-ops.html)
// 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.
// Cross-account use: This operation can't be used across different Amazon Web
// Services accounts. Related operations:
