Programming: Write a simple encryption program that uses a built-in pseudorandom number generator to generate a key stream. The user provides a key that is used as the generator’s “seed value.” The generator will take the seed value as its initial value and should always generate the same stream of numbers from that specific value. Use the resulting stream as a key stream for a cipher to encrypt the file. Verify that the encryption program can also decrypt the file. WARNING: Do not delude yourself into believing that this provides secure encryption
