Security Essentials Day 4

Hello, welcome to Introduction to Encryption I. This is one of the most important classes we have the privilege to teach as part of the SANS’ Security Essentials course. Encryption is real, it is crucial, it is a foundation of so much that happens. I guess you know that one of the SANS mottos is, “Never teach anything in a class the student can’t use at work the next day.” One of our goals in this course is to help you be aware of how cryptography is used in our world.
