How Encryption Works

Encryption is a powerful security tool that can protect confidential data, stop hackers from breaking in, and verify the identity of remote users. But how does this mysterious technology work? We’ll explain the basic concepts of encryption in a way that anyone can understand, and demystify common technologies like web site encryption, hard drive encryption, certificate-based authentication, digital signing, and more. Along the way, we’ll learn about the ways that hackers bypass and break encryption, and the key steps you can take to use it most effectively. As a bonus, we’ll learn about how cryptocurrency works, since it uses the same technology! After watching this talk, you’ll understand how encryption works, why it sometimes doesn’t, and what you can do to protect your organization.
