CompTIA® Security+™ Rapid Review (Exam SY0-301)

Chapter 6. Cryptography

Roughly 13 percent of the SY0-301 exam focuses on the topic of cryptography. You need to have a good grasp of the general concepts of cryptography, how to apply cryptographic concepts, and you must be able to explain the core concepts of public key infrastructure. Some readers worry that this domain will require them to learn the inner workings of algorithms, but that is not the case. This domain looks at how cryptographic solutions are used all around us in the workplace, at home, and in many business solutions such as Secure Sockets Layer (SSL) and IP Security (IPsec).

This chapter covers the following objectives:

• Objective 6.1: Summarize general cryptography concepts

• Objective 6.2: Use and apply appropriate cryptographic ...
