Preface

In today's world, it's important to have confidence while either transmitting or storing data. Cryptography can provide confidentiality, integrity, authentication, and non-repudiation. But just what exactly is involved when we use cryptographic techniques? Modern Cryptography for Cybersecurity Professionals will help you gain a better understanding of the cryptographic protocols and processes that are necessary to secure data.

We'll learn how encryption can protect data, whether in motion or at rest. You'll get a better understanding of symmetric and asymmetric encryption and learn how a hash is used. You'll also see how a public key infrastructure and certificates enable trust between parties, so we can confidently encrypt and exchange data. You'll then see the practical applications of cryptographic techniques, including passwords, email, and securely transmitting data using a Virtual Private Network (VPN).
