// 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 . For
// information about valid keys for this operation, see Understanding key
