Assignment: Write a program that calculates the authentication 
cryptograpms for Javacard secure messaging (for GXP211 PK (IS)).
Use any programming language, any crypto library, no user interface
is required (just a source code with constants definition is ok).
See annex D of the GP specifications and the worked example below.


Worked example:

Host challenge: 01 02 03 04 05 06 07 08
Card challenge: A1 A2 A3 A4 A5 A6 A7 A8

Static ENC key: CA CA CA CA CA CA CA CA 2D 2D 2D 2D 2D 2D 2D 2D
Static MAC key: 2D 2D 2D 2D 2D 2D 2D 2D CA CA CA CA CA CA CA CA

Derivation data (combined challenges): 
A5 A6 A7 A8 01 02 03 04 A1 A2 A3 A4 05 06 07 08

Session ENC key (encrypted ECB derivation data with static ENC key):
73 64 4D A1 E5 BC BF 93 FB 79 29 88 CA B3 42 53

Crypled ENC session key (odd bytes replaced with 2D, even with CA):
2D CA 2D 2D 2D CA 2D 2D 2D 2D 2D CA CA 2D CA 2D

Session MAC key (encrypted ECB derivation data with static MAC key):
7B D9 B6 31 1E 31 15 69 2D 94 F3 FB 63 CC 81 D6

Crypled MAC session key:
2D 2D CA 2D CA 2D 2D 2D 2D CA 2D 2D 2D CA 2D CA

Base for calculating cryptograms (concat of challenges and 80 00..):
01 02 03 04 05 06 07 08 A1 A2 A3 A4 A5 A6 A7 A8 80 00 00 00 00 00 00 00

Card cryptogram (CBC encryption of base with session ENC):
E6 27 6A F8 34 A4 5B 26

Base for calculating cryptograms (concat of challenges and 80 00..):
A1 A2 A3 A4 A5 A6 A7 A8 01 02 03 04 05 06 07 08 80 00 00 00 00 00 00 00

Host cryptogram:
