Dive into practical cryptography: symmetric and asymmetric encryption, hashing, salting, key exchange, digital signatures and certificates, PKI, cryptographic tools, and blockchain technology.
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.
This course is 43 mins long.
