Hi everyone! I hope you all had an enjoyable weekend and are making good progress on your work. This week’s discussion focuses on encryption and, specifically, how we can use encryption to ensure confidentiality.
Let’s start with the question: What is encryption, and why do we use it? What are some of the specific tools, utilities, or applications that utilize encryption for ensuring confidentiality (such as SSL, PGP, etc)?
Have a great week and, as always, let me know if you run into any problems or questions.
