Practicals

* Use your Roll Number for sample execution.

Part 1

1. Update the code of DES (week-9) for DES Decryption algorithm following the given constraints:

• Code must print the output for each of the following steps for both encryption and decryption:
  • Plaintext before and after padding
  • Data before and after every block
  • Data after each Round
  • Set of all (16) generated keys

Part 2

1. WAP to roll a die using basic socket programming in Python. Use the following instruction to solve the problem:

• There should be two python scripts, i.e., server.py and client.py
