Basic Cryptographic Terminologies
The Security+ exam is full of cryptographic terminologies, and in this section, we are going to start with obfuscation, which makes the code obscure. Try asking your family and friends to say the word obfuscation and watch them struggle. It is aptly named as the word itself is very obscure! You must know the terminology thoroughly.
Obfuscation
Obfuscation is the process where you take source code and make it look obscure, so that if it is stolen, it would not be understood. It is used to mask data. XOR, ROT13, and steganography could all be used for obfuscation in the Security+ exam.
Pseudo-Random Number Generator
Pseudo-Random Number Generator (PRNG) refers to an algorithm that uses mathematical formulas to produce sequences of random numbers. Random numbers can be used when generating data encryption keys.
Nonce
A nonce is an arbitrary number that can be used just once; it is often a random number.
