// 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 (https://docs.aws.amazon.com/payment-cryptography/latest/userguide/generate-pin-data.html)
// 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. For information about valid keys
// for this operation, see Understanding key attributes (https://docs.aws.amazon.com/payment-cryptography/latest/userguide/keys-validattributes.html)
