  1. Lake says:

    The correct answer is RSA. The RSA algorithm is an early public-key encryption system that uses large integers as the basis for the process. It’s widely implemented, and it has become a de facto standard. RSA works with both encryption and digital signatures. RSA is used in many environments, including Secure Socket Layer, and it can be used for key exchange.

    Who wrote these? They obviously haven’t used spell check a day in their lives, nor have they opened a text book. So many of these answers are wrong. Are these answers actually wrong on the real CompTIA Security + test? Or only wrong on this site?? I would hate to take the test and fail due to actually choosing the correct answers.
