Programming project: Simplified DES, part 1
30 points
In either Jave >= 8 or Python >= 3.7 implement one round of encryption of the textbooks simplified DES scheme. Write a program called SDESRound.java or sdesround.py so that it contains:
a method called encryptRound(plaintext, subkey) where the plaintext and the subkey are both integers. As specified in section 7.2 of the text, a plaintext contains 12 bits and, so is in the range 0 to 4095, and the subkey contains 8 bits, and so in the range 0 to 255. This method performs one round of the simplified DES scheme and returns the ciphertext after that round.
a main method that takes a plaintext integer and and a subkey integer as command line parameters, calls the encryption method, and prints the resulting ciphertext. I will run your code as follows:
python sdesround.py 128 250
java SDESRound 128 250

Here is an updated table with sample inputs and the expected output.
