Securing Your Digital Life - What is Encryption?

In this video we provide a non-technical introduction to the concept of encryption, explain why it is useful and who uses it, describe two primary types of modern encryption, and discuss what information you should consider encrypting.

This video provides a very high-level overview for viewers who are unfamiliar with the concept of encryption, and thus is appropriate for a general audience. No technical knowledge is required.
