Write a program that implements the DES round for both encryptionand decryption in Figure 3-6, page 70, where the input is 7A4FFF3BBCCCEF03, the key Kn is the 32-bit number 4AAAAABB, and the mangler function simply is an xor function of Rn and Kn. What is the output of the encryption part? For the decryption part, use the 64-bit output generated by the encryption part. What is the output of the decryption part?
