More details:

Full triple DES MAC as defined in ISO 9797-1 as MAC Algorithm 1 with

- Padding method 1: add  0 to the end of the data until the padded data is a multiple of 8

- Splitting the data in blocks of 8 bytes

- initial transformation 1

-output transformation 1 , without truncation

Must be used a triple DES, double length for MAC calculation.
