Javvad’s explanations are wonderful. He takes some of the more difficult concepts of the CISSP and places them in a context that is humorous and fun, yet accurate.
For example, his explanation of asymmetric cryptography is worth the price of the book.
Have you ever tried to explain asymmetric encryption to someone who has never heard of it?
It is a maddening process that usually adds confusion rather than clarification.
You can talk all about substitution and transposition of characters. You can scream about how to secretly exchange keys. You can do all this while your blood pressure rises and the person to whom you are explaining it just becomes more mystified at your gibberish rant.
However, if you read Javvad’s description of asymmetric cryptography, you will be able to explain it to anyone and watch their eyes light up as they start to understand the beauty of it.
Equally, if you are studying for the CISSP exam and that cryptography chapter is making you reconsider your career in InfoSec, read Javvad’s explanation and your eyes will light up, because you too will now understand.
