Cryptography in Action: Privacy for a Connected World

As data moves constantly across networks, devices, and platforms, cryptography has become the backbone of digital privacy and trust. Cryptography in Action: Privacy for a Connected World offers a practical and accessible guide to understanding how cryptographic techniques protect information in real-world systems.
This book goes beyond theory to explain how encryption, hashing, digital signatures, and key management are applied in modern applications. It highlights how cryptography safeguards communication, secures data at rest and in transit, and enables privacy in cloud, mobile, and connected environments. Complex concepts are explained clearly, making them approachable without sacrificing depth.
Inside this book, readers will learn:
• How cryptography enables privacy and trust in digital systems
• How encryption protects data across networks and devices
• How cryptographic failures lead to real-world breaches
• How cryptography supports authentication and integrity
• How to apply cryptographic principles responsibly and effectively
Written in a clear, structured, and practical style, this book is ideal for students, developers, security professionals, and technology leaders. Cryptography in Action equips readers with the knowledge to understand, evaluate, and apply cryptography to protect privacy in an increasingly connected world.
