Problem
1. Write two computer programs to simulate a Unicode streamcipher that consists of both
encryption and decryption algorithms. The encryption programaccepts inputs from an
existing text file, called â€œletter.txt.â€ The encryption programproduces an output ciphertext
file, called â€œsecretâ€ The decryption program takes â€œsecretâ€ asinput and decrypts it into a
plaintext, called â€œmessage.txt.â€

- The random â€œseedâ€ must be known, but be kept secure, by thepseudorandom number
generators in both encryption and decryption programs.
Note from me: Use Java.
