Assume a company operates an educational/learning website with very low-cost courses. Visitors can purchase courses with a credit card by providing information such as the credit card number, expiration date, and 3-digit CVC code (written on the back of the credit card). After a successful payment, a service called "Secure Transfer" operates in the background and sends all of the visitor's credit card information to another server over a highly secure channel. If the service/server takes too long to acknowledge a visitor's request, it will leave an unfavorable impression. The website is well-known on the internet, with thousands of visitors each day.
Discussion Topic:
Which encryption method, in your opinion, should be utilized in the "Secure Transfer" service?
