Security software program

I need you to develop some software for me. I would like this software to be developed for Windows . 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. 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 cipher *text_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
