Master Cryptographic Methods in IT Security 🔒

In this unit, you become acquainted with the application of cryptographic algorithms. Hash values are the first type covered, followed by symmetric algorithms. Asymmetric algorithms follow, and then common cryptographic applications are presented. The unit then presents public key infrastructure (PKI), the essential elements to manage public keys. Much of this unit is a repeat from earlier material, but what is important to learn is which cryptographic algorithms are employed under which circumstances
