Do you believe that all data should be encrypted? Many computing professionals think this is a good idea. But a small number of computing experts feel that no data should be encrypted that all data and software should be openly available to anyone who wants it. Explain your answer (whether you believe all data should or should not be encrypted).
In this module, you learned that random numbers (or, at least, pseudorandom numbers) are essential in cryptography, but it is extremely difficult even for powerful hardware and software to generate them. Go online and conduct research on random number generators. What are the different uses of these tools besides cryptography? How do they work? Explain your answer using your own words in 2-3 paragraphs.
