java coding

Write two computer programs to simulate an Unicode stream cipher that consists of both encryption and decryption algorithms.

The encryption program accepts inputs from an existing text file, called “letter.txt.” This can have anything in it.

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.”

(Hint: the random “seed” must be known, but be kept secure, by the pseudorandom number generators in both encryption and decryption programs
