CompTIA Security+: Practical Cryptography

Cryptography is at the heart of many security controls and countermeasures and as such Security+ candidates must have a solid grasp of practical cryptography.

In this course you will discover symmetric and asymmetric cryptography and compare different encryption levels including full disk and partition. Next you will explore hashing salting hash-based message authentication codes (HMACs) and key exchange. Then you will examine digital signatures certificates and public key infrastructure (PKI) focusing on certificate authorities (CAs) certificate signing request (CSR) generation and Online Certificate Status Protocol (OCSP). Finally you will investigate cryptographic tools like Trusted Platform Module (TPM) hardware security module and key management systems and you will dive into blockchain technology.

This course is part of a series that prepares you for the CompTIA Security+ (SY0-701) exam.
