Write two computer programs to simulate a Unicode stream cipher that consists of both encryption and decryption algorithms. The encryption program accepts inputs from an existing text file, called "letter.txt." The encryption program produces an output ciphertext file, called "secret." The decryption program takes "secret" as input and decrypts it into a plaintext, called "message.txt." The random "seed" must be known but kept secure by the pseudorandom number generators in both the encryption and decryption programs.
