Hands-On Cryptography with Python

Detailed Summary of the Book

In "Hands-On Cryptography with Python," you'll journey through the fascinating world of cryptography, starting with the basics and advancing to complex protocols and algorithms. The book combines accessible explanations of cryptographic concepts with Python-based hands-on projects that solidify your understanding by applying what you learn.

The book begins with an introduction to the fundamental principles of cryptography, explaining what it is, why it matters, and how it has shaped the digital age. As you progress, you'll explore classical ciphers and learn why these early encryption techniques were both revolutionary and flawed. In later chapters, the book delves into modern cryptographic algorithms, such as AES (Advanced Encryption Standard) and RSA, as well as hashing techniques like SHA (Secure Hash Algorithm).

Beyond the basics, "Hands-On Cryptography with Python" introduces you to advanced topics, including digital signatures, public-key infrastructure (PKI), blockchain-based systems, and secure communication protocols. For every concept introduced, there are practical examples and Python scripts to demonstrate real-world implementation. By the final sections, you'll even gain insights into vulnerability analysis, cryptanalysis, and building secure applications.

Whether you're securing personal projects, protecting sensitive enterprise data, or simply curious about how cryptography works in our digital world, this book offers the perfect blend of knowledge and practice.
