In recent years, the world has witnessed an exponential increase in data. As applications—such as those belonging to financial institutions and governments—become more widespread and the traffic over insecure networks increases, it becomes increasingly important to understand information security principles and techniques. With this goal in mind, “Everyday Cryptography” introduces learners to different aspects of cryptography.

The course begins by explaining the key pillars of information security. It introduces the learner to private and public key encryption principles, together with popular algorithms. It then covers authentication and data integrity techniques, followed by a discussion on key management. The course concludes with a review of real-world cryptography and government policy concerns.

After taking this course, you’ll have a good understanding of information security basics as well as the system’s strengths and shortcomings. You’ll also be able to apply the strategies to different use cases.
