// expiration date of the card are required to check its validity during
// transaction processing. To begin this operation, a CVK (Card Verification Key)

// or ImportKey (https://docs.aws.amazon.com/payment-cryptography/latest/APIReference/API_ImportKey.html)
// to establish a CVK within Amazon Web Services Payment Cryptography. The
// KeyModesOfUse should be set to Generate and Verify for a CVK encryption key.
