Create a program to encrypt and decrypt binary files using S-DES (Simplified DES) in the Cipher Block Chaining mode. The program takes the input of an initial key and an initial vector, reads the plaintext or ciphertext from a file, conducts the encryption or decryption, and writes the resulting ciphertext or plaintext into a second file.

You can use any of your preferred programming languages and operating systems. If the programming language is not C/C++/Java/Python, you will need to demo your code on your own computer.

Your program must following the following input and output formats. Input Format: The program should take a command in the following format. (java) mycipher -m mode -k initial_key -i initial_vector -p plaintext_file -c ciphertext_file mode: can be only encrypt or decrypt initial_key: 10-bit initial key initial_vector: 8-bit initial vector plaintext_file: a binary (not text) file to store the plaintext ciphertext_file: a binary (not text) file to store the ciphertext

Output Format: The program should print output in the following format. k1=subkey 1 k2=subkey 2 plaintext=all bytes of the plaintext separated by blanks, starting from the first byte ciphertext= all bytes of the ciphertext separated by blanks, starting from the first byte Sample Screen Shot:
