// Generates a Message Authentication Code (MAC) cryptogram within Amazon Web
// Services Payment Cryptography.
//
// You can use this operation to authenticate card-related data by using known
// data values to generate MAC for data validation between the sending and
// receiving parties. This operation uses message data, a secret encryption key and
// MAC algorithm to generate a unique MAC value for transmission. The receiving
// party of the MAC must use the same message data, secret encryption key and MAC
// algorithm to reproduce another MAC value for comparision.
//
// You can use this operation to generate a DUPKT, CMAC, 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 .

// Web Services Payment Cryptography User Guide.
